Survey study 397 Randomised trial 126 Cohort study 66 Study 45 Non-randomised trial 38 Case-control study 32 Cohort study, 2026 What genetic factors are linked to premenstrual symptoms? One genetic location on chromosome 12 was clearly associated with PMS. The genetic factors linked to PMS are also linked to depression. Systematic review, 2026 Are hormone levels different in women with PMS? Women with PMS have higher estrogen levels during the luteal phase (p=0.014), but progesterone levels are not consistently different. Studies used different methods and small samples. Randomised trial, 2026 Does taking alpha-lactalbumin supplement for three months help with period-related symptoms? No significant overall difference compared to placebo. Some exploratory analyses found minor improvements in weight gain and lowered motor coordination, and possibly in quality of life. These exploratory findings need confirmation. Randomised trial, 2026 Does calcium and vitamin D supplementation reduce PMS symptoms? Yes. Women taking 1,000 mg calcium daily plus 50,000 IU vitamin D every two weeks for 12 weeks showed significantly greater improvements in anger, anxiety, food cravings, physical symptoms, and work efficiency compared to placebo. Systematic review, 2026 Can digital tools help diagnose PMDD? Digital tools show promise for diagnosing PMDD by helping you track symptoms, but most need more testing and better integration with healthcare systems before they're widely used. Systematic review, 2025 Does zinc supplementation help with PMS symptoms? Yes. Zinc supplements significantly reduced physical symptoms, anger, anxiety, tearfulness, difficulty concentrating, insomnia, and overeating compared to placebo. Randomised trial, 2025 Does mood, well-being, and sexual function change across the menstrual cycle? No, there were no meaningful changes in sexual function, mood, or well-being across menstrual cycle phases in healthy young women. Being in a stable relationship predicted better sexual function overall, but cycle phase did not. Randomised trial, 2025 How effective are non-hormonal treatments for severe PMS? All three tested treatments significantly reduced PMS symptoms more than placebo. Calcium-vitamin D was most effective, followed by cognitive behavioral therapy and lifestyle changes. Randomised trial, 2025 Does the PMSoff supplement help PMS and PMDD symptoms? Yes, based on this trial. The 218 women taking PMSoff had significantly better symptom relief after one month compared to placebo, and even greater relief after two months. Systematic review, 2025 Which patient-reported tools accurately measure PMS and PMDD in Japanese? Some tools like the New Short-Form Premenstrual Symptoms Questionnaire and Japanese Daily Record of Severity of Problems showed good structural validity and internal consistency. However, most tools need further validation research. Randomised trial, 2025 Does exercise reduce menstrual symptoms and sleep problems? Yes. Women who exercised for 12 weeks had significantly fewer menstrual symptoms and better sleep than those who did not exercise. Randomised trial, 2024 Is Jiawei Xiaoyao pill effective and safe for treating premenstrual syndrome? Yes, women who took Jiawei Xiaoyao pill experienced significantly greater reduction in PMS symptoms than those taking placebo (p=0.002 and p=0.001), with no serious side effects reported. Randomised trial, 2024 Does estetrol/drospirenone birth control improve PMS symptoms? Yes. Women who started this birth control experienced significant improvements in pain, bloating, and negative mood symptoms. Women already on other birth control saw minimal improvements. Randomised trial, 2024 Is Ganyushu Granule effective and safe for premenstrual syndrome? Yes, both high-dose and low-dose Ganyushu Granule reduced PMS symptoms better than placebo starting from the second cycle, with high-dose showing the fastest improvement and no serious side effects. Randomised trial, 2024 Does Echium amoenum and Foeniculum vulgare combination reduce PMS symptoms? Yes. The herbal combination taken in the second half of the menstrual cycle significantly improved PMS symptoms and quality of life over two months. Review, 2024 What are the most effective treatments for PMDD? According to this literature review, SSRIs (antidepressants) and cognitive-behavioral therapy are the most commonly recommended first-line treatments. Birth control pills with drospirenone are also effective. Systematic review, 2024 Does yoga help reduce PMS symptoms? Yes, yoga appears to help reduce emotional, behavioral, and physical PMS symptoms and improve quality of life. The evidence comes from a systematic review of 14 randomized controlled trials. Cohort study, 2023 Is PMDD a valid medical diagnosis? Yes. PMDD is recognized by the World Health Organization and American Psychiatric Association as a distinct medical diagnosis. Evidence suggests it has real neurobiological basis, though more biological research is still needed to fully understand it. Systematic review, 2023 Is PMDD linked to depression? PMDD and depression are strongly linked. Nearly all studies found that people with PMDD were more likely to have depression, and people with depression were more likely to have PMDD. Randomised trial, 2023 Does zinc supplementation reduce PMS symptoms in women? Yes. Daily zinc supplementation for 24 weeks significantly reduced multiple PMS symptoms including anger, anxiety, depressed mood, and physical symptoms like breast tenderness and bloating compared to placebo. Guideline, 2023 How are GnRH agonists used to treat PMDD that doesn't respond to standard medications? GnRH agonists combined with hormone replacement are effective for severe PMDD that doesn't respond to first-line treatments, but many doctors don't know how to use this option. Systematic review, 2022 Do herbal medicines and nutritional supplements help premenstrual syndrome symptoms? Yes, herbal medicines and nutritional supplements appear effective in reducing PMS symptoms, especially physical symptoms. Adverse events were mild or absent in most trials. Cohort study, 2022 Does body size during childhood affect the risk of premenstrual disorders later? Yes. Girls with higher BMI in childhood and adolescence had higher risk of developing premenstrual disorders by young adulthood. This association remained even after accounting for depression, anxiety, and other mental health conditions. Cohort study, 2022 Can women accurately tell if they have period-related migraines, or do they need to track them? No. Women couldn't accurately tell if they had period migraines. Most needed to keep a daily headache diary for several cycles for accurate diagnosis. Cohort study, 2021 Does when you start puberty affect your risk of premenstrual disorders as an adult? Women who started menstruating later had lower risk of premenstrual disorders in adulthood. Women who had early pubic hair growth had higher risk of premenstrual disorders. Randomised trial, 2021 Does ulipristal acetate (a progesterone blocker) treat PMDD? Yes. Women taking 5 mg daily improved by 41% versus 22% on placebo. Half achieved remission with the medication compared to 21.1% on placebo. Randomised trial, 2020 Does adding fluoxetine to birth control pills help with severe PMS? Yes. Adding fluoxetine to birth control pills helped more women with severe PMS than pills alone. In the final month, 65% of women taking both improved, versus 50% on pills alone. Survey study, 2020 What symptoms best predict whether PMDD will seriously affect daily life? Four premenstrual symptoms is the optimal number for predicting clinically significant impairment. Psychological symptoms like difficulty concentrating were the strongest predictors, more so than core mood symptoms. Randomised trial, 2017 Does the combined oral contraceptive pill affect mood? Yes, but effects vary by cycle phase. The pill causes small increases in anxiety and irritability between periods but improves depression in the days before menstruation. Systematic review, 2017 Is Vitex agnus castus safe and effective for treating PMS and PMDD? All 8 included trials showed Vitex agnus castus was better than comparison treatments and was well tolerated, but the studies used different definitions of PMS, different outcome measures, and different Vitex preparations, making confident conclusions difficult. Randomised trial, 2015 Which birth control pill better reduces PMS and menstrual symptoms: nomegestrol acetate or drospirenone? Nomegestrol acetate reduced more PMS and menstrual symptoms than drospirenone pills in this large study of 3522 women, though drospirenone was better for emotional arousal. Randomised trial, 2015 Does taking sertraline only when PMDD symptoms start, instead of every day, help? Yes, taking sertraline just during the symptomatic days of the cycle improved mood and irritability more than placebo, though the main symptom scale did not quite reach statistical significance. Randomised trial, 2012 Does continuous birth control help women with PMDD? Continuous birth control pills reduced PMDD symptoms more than placebo. About 52% of women on the pill improved by at least half, compared to 40% on placebo. Randomised trial, 2011 Does a 24/4 birth control pill help women with PMDD improve work, relationship, and social functioning? Yes. The pill significantly improved problems at work, in relationships, and in social activities compared to placebo, with the greatest improvements appearing in the first cycle. Randomised trial, 2011 Does a birth control pill reduce negative emotions, food cravings, and water retention in women with PMDD? Yes, the pill significantly reduced all three symptom clusters compared to placebo in all three treatment cycles. The greatest improvements happened in the first cycle. Randomised trial, 2009 Does Yasmin birth control reduce PMS symptoms better than another pill? Yes. Yasmin reduced water retention, improved breast tenderness, and improved skin problems more than desogestrel pill. Both prevented pregnancy well. Randomised trial, 2009 Does Vitex agnus castus reduce PMS symptoms in Chinese women? Yes, Vitex agnus castus significantly reduced PMS symptoms better than placebo. Symptoms improved in both groups, but the herbal medicine group improved more, though the large placebo improvement (50%) means some benefit may not be from the herb itself. Systematic review, 2008 Do SSRIs (a type of antidepressant) help PMS and PMDD symptoms? Yes. SSRIs reduce symptoms of PMS and PMDD, and continuous daily dosing works better than taking the medication only during certain cycle phases. Randomised trial, 2007 Can a short questionnaire on the first day of menstruation screen for PMS? Yes, the DRSP questionnaire given on the first day of menses can screen for PMS. It is better at ruling out PMS (correctly identifying 83-84% of women who don't have it) than at finding it (identifying 53-55% of women who do have it). Randomised trial, 2005 Are visual analog scales valid for measuring PMDD symptoms? Yes. The revised visual analog scale reliably measures PMDD symptoms with consistent results whether women assess symptoms as they happen or from memory. Review, 2004 How should doctors diagnose and treat PMS and PMDD? Doctors can now diagnose these conditions using specific prospective symptom tracking and have several evidence-based treatments. Antidepressants that increase serotonin, especially when taken only during the luteal phase, work best for severe symptoms. Randomised trial, 2002 Does taking sertraline only during the luteal phase help premenstrual dysphoric disorder? Yes. Women taking sertraline during the second half of their cycle showed significant improvement compared to placebo, with few side effects. Randomised trial, 2002 Does daily fluoxetine help PMDD? Yes. Fluoxetine 20 mg improved mood and physical symptoms compared to placebo. The 10 mg dose showed some benefits but was not as strong. Both were well tolerated. Randomised trial, 2002 Does taking fluoxetine only before your period help PMDD? Yes, at a dose of 20 mg per day. This dose reduced mood symptoms and physical symptoms like breast tenderness and bloating, starting 14 days before the period through the first day of bleeding. Randomised trial, 2002 Does taking fluoxetine only during the luteal phase help PMDD? Taking fluoxetine 90 mg twice during the luteal phase significantly improved PMDD symptoms, mood, social functioning, and quality of life compared to placebo or taking it once. This was a randomized double-blind placebo-controlled trial with 257 women. Randomised trial, 2000 How effective are antidepressants for treating PMDD? Serotonin reuptake inhibitors (a type of antidepressant) are very effective for PMDD, with excellent results and minimal side effects. Treating only during the premenstrual phase works nearly as well as daily treatment. Randomised trial, 2000 Does sertraline improve how women with PMDD feel and function? Yes. Sertraline was clearly better than placebo at improving how women with PMDD functioned and their quality of life, and improvements appeared by the second month of treatment. Randomised trial, 1999 Is sertraline taken only during the luteal phase effective for PMDD? Yes, sertraline taken during the luteal phase significantly reduced PMDD symptoms including mood and physical symptoms, and was well tolerated with insomnia as the main side effect in 14% of women. Randomised trial, 1997 Does Vitex agnus castus work better than vitamin B6 for premenstrual tension syndrome? Both reduced symptoms by similar amounts (47-48%), but more women on Vitex reported excellent results and had no remaining complaints, suggesting Vitex may work better for PMTS. Randomised trial, 1986 Does suppressing ovulation with estradiol implants and progestin help severe premenstrual syndrome? Yes, estradiol implants combined with cyclical progestin significantly relieved symptoms. The effect lasted throughout treatment, even though a very high proportion of placebo-treated women also improved. Survey study, 2026 Does childhood trauma cause worse PMS, and can social support help? In a study of 629 women in Iran, childhood trauma was associated with more severe PMS, while strong perceived social support was associated with less severe PMS. Social support appeared to reduce the negative effect of trauma on PMS. Survey study, 2026 Is PMS worse in medical students with higher stress? Yes. Medical students with high stress are much more likely to have moderate to severe PMS. About 26.5% of students had moderate to severe PMS overall. Cohort study, 2026 Does having worse premenstrual symptoms mean you are more likely to get pregnant? Women with more severe premenstrual symptoms were more likely to get pregnant during infertility treatment, with pregnancy rates rising from 12.7% to 35.0% across severity groups. However, the reason is unclear because hormone levels were not measured. Survey study, 2026 How does PMS affect test anxiety in nursing students? PMS was linked to higher test anxiety both directly and indirectly through delaying sleep and reduced ability to pay attention. The indirect pathway through sleep delays and attention difficulties accounted for 50% of the link between PMS and test anxiety. Survey study, 2026 Are PMDD and ADHD linked in women with bipolar disorder? In women with bipolar disorder, 44.2% have PMDD, and those with PMDD also have higher ADHD symptom scores. Genetic risk for ADHD was linked to both PMDD severity and ADHD symptoms. Survey study, 2026 Does the French version of the Menstrual Distress Questionnaire work reliably? Yes. The French version is reliable and valid for measuring menstrual distress in French-speaking women, though French women reported higher symptom scores than English and Italian versions, particularly about period bleeding. Non-randomised trial, 2026 Do dietary changes or sun exposure reduce PMS symptoms in adolescent girls? Yes. Both dietary intervention and sun exposure significantly reduced PMS symptoms compared to health education alone. Sun exposure was slightly more effective, with 52.3% of girls showing clinical improvement compared to 46.5% in the diet group. Survey study, 2026 Does diet affect PMS severity? Yes. Women eating a Western-style diet were 2.35 times more likely to have severe PMS than those with a healthy diet. Women eating very little food had up to 3 times higher odds of moderate or severe PMS. However, this does not prove diet causes PMS. Lab study, 2026 Do core stability exercises help women with PMDD? Yes. After 8 weeks of core stability exercises, women with PMDD had reduced pain and improved ability to do daily activities. Non-randomised trial, 2026 Does yoga reduce PMS symptoms and improve physical fitness in women? In this study of 34 women, 8 weeks of yoga significantly reduced PMS symptoms and improved body composition and hip mobility. The study had a control group, which is stronger than uncontrolled studies, but was not randomized. Survey study, 2026 Do nursing students with PMS experience excessive daytime sleepiness? Yes, most experienced mild sleepiness (55.1%) and sleepiness increased with PMS severity. However, only 2 students had severe PMS, so we cannot be confident about that group.

Cohort study, 2026 Does cannabis use vary across the menstrual cycle in people with premenstrual disorders? Yes, the amount of cannabis used peaks before menstruation and around ovulation in people with premenstrual disorders. The pattern is stronger when emotional symptoms worsen. Randomised trial, 2026 Do specially optimized meals based on dietary guidelines help premenstrual disorder symptoms? Yes. Women eating these optimized meals had lower symptom scores both before and during menstruation compared to those eating their usual diet, and lower overall symptom scores. Survey study, 2026 What is the true rate of PMDD, and does it worsen mental health conditions? The true rate of PMDD when properly diagnosed is 3.2%. Depression, bipolar disorder, and schizophrenia can all worsen during certain times of the menstrual cycle, and SSRIs and hormonal therapies are proven treatments. Survey study, 2026 How common is PMDD among college women and what increases the risk? About 17.4% of college women screened positive for probable PMDD. Living with a boyfriend, having severe period pain, and having longer menstrual cycles were associated with higher odds. Survey study, 2026 How common is PMDD among female medical students and what triggers it? 11% screened positive for PMDD and 42.5% had moderate-to-severe PMS. Main triggers were stress, poor health, poor nutrition, and exams, though most managed symptoms without seeing a doctor. Survey study, 2026 Do how you think about your period and how you manage emotions affect PMS and PMDD? Yes. How you view your period and whether you reframe difficult thoughts (cognitive reappraisal) matter. Women who reframe thoughts had less distress, while those who suppress feelings and deny menstrual impact had more. Cohort study, 2026 What life and psychological factors are linked to PMS and PMDD? Both are linked to smoking, childhood trauma, poor mental health, and poor work-life balance. PMDD is also linked to being married with children. PMS is linked to alcohol use. Survey study, 2026 Does the Chinese version of the PMS screening questionnaire work well? Yes. The Chinese version is reliable and valid for identifying PMS and PMDD in Chinese college students.

This is a well-designed study. Review, 2026 How does the menstrual cycle affect concentration and work productivity? Reaction time slows and attention problems occur most during the luteal and premenstrual phases, particularly in people with PMS or PMDD. Overall evidence is mixed because studies use different methods. Case-control study, 2025 Are there differences in brain structure and inflammation in women with PMS? Yes, women with PMS show changes in brain structure and higher inflammation markers. These brain changes and inflammation are linked to symptom severity. Case-control study, 2025 Are there brain differences in women with PMS? Yes.

Women with PMDD had stronger cravings for highly sweet foods before their period, while healthy women did not show this pattern. The difference was clear. Survey study, 2018 Do exercise, nutrition, or stress affect how severe PMS symptoms are? Stress matters. Women with higher perceived stress had more severe PMS symptoms. Exercise intensity and nutrition did not significantly predict PMS severity. Randomised trial, 2018 Does adding homeopathy to regular treatment help PMS or PMDD? Yes, the homeopathy plus usual care group improved significantly more than usual care alone (p=0.03). However, the researchers said a larger international trial would not be practical because recruitment was extremely difficult.

Cohort study, 2010 How common is PMDD in women with bipolar disorder? About 27% of women with bipolar disorder have a lifetime history of PMDD. When PMDD occurs with bipolar disorder, it is linked to more severe bipolar subtypes and other mental health conditions like postpartum depression and obsessive-compulsive disorder. Survey study, 2010 How much does PMS affect the daily lives of Korean women? PMS is extremely common in Korean women, with 32% meeting clinical criteria for PMS, and it significantly disrupts daily activities. However, almost none of the women knew what PMS or PMDD was or sought medical help for it. Survey study, 2009 What premenstrual and menstrual symptoms do Chinese women experience? About 18.6% to 34.2% of Chinese women reported 10 or more menstrual symptoms, showing that PMS is common in Chinese women at similar rates to Western populations. Survey study, 2009 How common is PMS in young Iranian women? PMS is very common: almost all young women have at least one PMS symptom, and 16% have clinically significant PMS. Younger women aged 18-20 have more severe symptoms than slightly older women. Survey study, 2009 How common is PMDD among American women? Only 1.3% of women met full PMDD criteria using strict diagnostic rules. This is much lower than previous research suggested. Survey study, 2008 Can we measure how much premenstrual symptoms affect a woman's quality of life? Yes. Researchers developed a brief 6-item survey that accurately identifies women with significant PMS or PMDD and measures its impact on daily life. Survey study, 2008 Can a simple checklist help identify menstrual migraine? Yes. A 3-question tool works well at identifying menstrual migraine in women at gynecology clinics. Cohort study, 2008 How common is PMS in medical students and how much does it affect their quality of life? 51% of medical students had PMS, with 5.8% having severe PMDD. PMS significantly impaired their mental and physical quality of life and academic performance. Survey study, 2008 What factors are linked to PMS in Thai nurses? Coffee consumption and having a negative attitude toward menstruation are the strongest factors linked to PMS in this group. 25.1% of Thai nurses have PMS. Cohort study, 2008 Do women with autism have PMS more often than women without autism? Yes, women with autism had much higher rates of PMS compared to women without autism. In the autism group, 92% showed PMS symptoms, while only 11% of the control group did. Non-randomised trial, 2007 Does a birth control pill with drospirenone reduce water retention symptoms? Yes. Women taking this pill had significant reduction in water retention symptoms during the premenstrual and menstrual phases, with no weight gain. Case-control study, 2007 Are there genes that increase the risk of PMDD? Genetic variations in the ESR1 gene (which codes for estrogen receptor alpha) appear linked to PMDD mood symptoms, suggesting genetic factors contribute to who develops the condition. This was found in a study of women with PMDD and unaffected controls. Randomised trial, 2007 Do extended-cycle birth control pills reduce PMS symptoms compared to regular pills? Yes. Switching from regular birth control pills (21 days on, 7 days off) to extended-cycle pills (minimal pill-free time) significantly reduced PMS symptoms, especially in women with more symptoms to start with. Survey study, 2007 How common is severe PMS and what are the most common symptoms? Severe PMS affects about 6.1% of women. The most frequent symptoms are irritability and anxiety, and most women with severe PMS have significant life disruption. Randomised trial, 2007 Do extended-cycle birth control pills reduce PMS symptoms compared to regular pills? Yes. Switching from regular birth control pills (21 days on, 7 days off) to extended-cycle pills (minimal pill-free time) significantly reduced PMS symptoms, especially in women with more symptoms to start with. Survey study, 2006 Is the DRSP questionnaire reliable for diagnosing PMDD? Yes. The DRSP reliably measures PMDD symptoms and detects changes from treatment, with high test-retest reliability and internal consistency. Non-randomised trial, 2006 Do extended-cycle birth control pills reduce premenstrual symptoms compared to regular pills? Yes. Women taking extended-cycle pills (periods only 4 times a year) had significantly fewer premenstrual-type symptoms, with the greatest improvement in women who had the most severe cyclic mood changes on regular pills. Randomised trial, 2005 Which birth control pill reduces PMS symptoms better: drospirenone or levonorgestrel? Drospirenone-containing pills reduced PMS symptoms more effectively than levonorgestrel pills after six cycles, especially mood symptoms and water retention. Randomised trial, 2005 How do PMDD symptoms start, end, and vary from cycle to cycle? Very variably. Symptoms peak 2 days before the period on average, but timing and duration differ by 4 or more days between cycles in nearly half of women studied. Study, 2005 When do menstrual symptoms peak in women without PMS or PMDD? All tracked symptoms peaked on the first day of menstruation, reaching much higher severity than each woman's typical average. Randomised trial, 2005 Can a birth control pill with drospirenone help PMDD symptoms? Yes. In this study, the drospirenone pill worked better than a placebo (dummy pill) at reducing PMDD symptoms. Study, 2004 Do these rating scales work for diagnosing premenstrual disorders? Yes. Two symptom rating scales translated into German reliably measure premenstrual symptoms and can help diagnose premenstrual disorders. Cohort study, 2004 Do women with bipolar disorder on mood-stabilizing medication experience premenstrual symptom worsening? No, women with bipolar disorder on mood-stabilizing treatment (lithium or valproate) experienced significantly less premenstrual symptom worsening than healthy women, suggesting the medication may protect against it. Cohort study, 2003 Does Yasmin birth control reduce premenstrual symptoms? Yes. Women taking Yasmin showed significant improvements in premenstrual symptoms and quality of life. Cohort study, 2003 Does the Moos Menstrual Distress Questionnaire accurately measure different types of menstrual cycle symptoms? Yes, when women filled out the questionnaire daily for 70 days, symptoms grouped into six main types, similar to the original questionnaire structure. This suggests the tool is useful, though some symptoms fit into multiple categories. Randomised trial, 2002 Does therapy work as well as an antidepressant for PMDD, and does combining them work better? Both therapy and antidepressant work well for PMDD with no difference in results after 6 months. Therapy maintains its effects better after treatment ends. Combining them does not help more than either one alone. Cohort study, 2002 What are the best ways to measure menstrual cycle symptoms? Researchers and clinicians can use either questionnaires asking about past symptoms or daily diaries. Many modern tools build on two foundational questionnaires: the Menstrual Distress Questionnaire and Premenstrual Assessment Form, each with different strengths and weaknesses. Randomised trial, 2002 Does the birth control pill Yasmin help women with PMDD? Yes, women taking Yasmin had greater reduction in premenstrual symptoms compared to placebo, with statistically significant improvements in appetite, acne, and food craving. Review, 2002 Does the new oral contraceptive Yasmin improve premenstrual symptoms and well-being? Yes. Women with premenstrual symptoms who took Yasmin showed improved well-being scores and fewer physical symptoms compared to before starting the medication. Lab study, 2002 Is the COPE daily diary a reliable way to track PMS symptoms? Yes. The COPE diary is reliable for tracking PMS symptoms. Symptoms increase consistently during the luteal phase and group into four recognizable patterns. Survey study, 2002 Can a computer program track period symptoms as accurately as traditional methods? Yes. A computer-based tracking system measured period blood loss, period pain, and PMS symptoms as accurately as traditional paper methods. Most women preferred the computer tool. Cohort study, 2002 How common is PMDD in midlife women, and what raises the risk? In this large community study, about 6.4% of women who tracked symptoms daily actually met the criteria for PMDD. Lower education, a past history of major depression, and current smoking were linked to higher odds of PMDD, while not working outside the home was linked to lower odds. Cohort study, 2002 How common is PMDD and does it stick around? PMDD affects 5.8% of young women and tends to persist. Most women with PMDD also have anxiety or other mental health conditions, use healthcare more, and have higher suicide rates. Non-randomised trial, 2001 Does a new birth control pill reduce PMS symptoms? Yes. In 322 women, after 6 cycles of this pill, negative mood and water retention during the premenstrual phase dropped significantly. However, this study had no control group, so we cannot be certain the pill itself caused the improvement rather than a placebo effect. Randomised trial, 2001 Does homeopathy help premenstrual syndrome symptoms? Yes, according to this small pilot study, homeopathy helped more women than placebo, though both groups improved and the difference was modest. Randomised trial, 2001 Does an oral contraceptive with drospirenone and ethinyl estradiol treat PMDD? The birth control pill showed signs of helping, especially with appetite, acne, and food cravings. However, most improvements were not statistically significant, and the study had limitations. Randomised trial, 2000 Is drospirenone-based birth control as effective as desogestrel-based, and which is better tolerated? Both prevent pregnancy equally well. The drospirenone-based pill caused less weight gain and reduced PMS symptoms more during treatment. Case-control study, 2000 Do eating habits change differently before the period in obese versus non-obese women? Yes. Both groups show increases in binge-eating symptoms before their period, but the cause differs: in non-obese women, eating changes correlate with mood symptoms, while in obese women they correlate with physical symptoms. Case-control study, 1999 What are the main symptom patterns in PMDD? PMDD has five distinct symptom groups: anger and irritability, depressed mood, anxiety and tension, decreased energy with physical symptoms, and eating problems. These patterns were identified through analysis of 99 women's symptoms. Survey study, 1998 Do women who had premenstrual problems earlier have more mental health issues during menopause? Yes. Women who reported premenstrual dysphoria were much more likely to have psychiatric symptoms at menopause. However, this is cross-sectional so we don't know if one caused the other. Randomised trial, 1997 Does a yeast-based dietary supplement reduce PMS symptoms? Yes. By 6 months, the yeast-based supplement (Sillix Donna) reduced symptom scores to 18% of baseline levels, much more than placebo which reduced them to 73%. Study, 1997 Does the time of the menstrual cycle affect how women answer questions about mood? No. Women's answers about mood symptoms are just as reliable and consistent regardless of where they are in their menstrual cycle. All women scored higher than men overall, but cycle phase didn't change this. Randomised trial, 1996 What is premenstrual dysphoric disorder (PMDD) and what treatments work for it? PMDD is a severe form of premenstrual mood disturbance, separate from milder PMS, and this review reports that SSRIs and treatments that stop ovulation (hormonal or surgical) have been shown effective in placebo-controlled trials. Survey study, 1996 Is the Daily Symptom Report a reliable way to diagnose PMS? Yes, the Daily Symptom Report is a reliable way to diagnose PMS, with very high internal consistency of 0.92. It measures mood, behavior, pain, and physical symptoms separately. Survey study, 1996 What symptoms do women experience before their period, and do they stay the same over time? Women experience five main types of symptoms in the week before their period: mood symptoms, hot flashes, body aches, muscle and nerve symptoms, and sleep problems. Mood symptoms are most consistent over time. Randomised trial, 1995 Does danazol help severe PMS? Yes, danazol significantly reduced severe PMS symptoms compared to placebo, with 43.8 percent of women becoming symptom-free versus 8.3 percent on placebo. Survey study, 1993 Is the PMS questionnaire reliable and what are the main symptom patterns? Yes, the questionnaire is very reliable (0.94 internal consistency). It shows that PMS symptoms fall into two main patterns: dysphoria (mood problems) and dysfunction (difficulty functioning in daily life). Cohort study, 1993 What does the pattern of premenstrual syndrome symptoms look like across the menstrual cycle? Symptoms clearly increase starting about 7 days before menstruation and peak on the second day of the next period. However, when researchers checked the same women again over 2 years, fewer of them still met the criteria for PMS. Study, 1993 What kinds of changes do women experience before their period? Most women experience a mix of both positive and negative feelings before their period, not just negative symptoms. Only nine women out of 112 had severe changes, and none had PMDD. Cohort study, 1991 Does having a mother with PMS affect a daughter's symptoms? Adolescents and adults experience similar severity of premenstrual symptoms, but when mothers have PMS, both mothers and daughters tend to experience significantly more premenstrual symptoms than families without PMS. This suggests PMS may run in families. Study, 1991 Does exposure to DES before birth affect period symptoms in adult women? Mostly no. Women exposed to DES in the womb reported similar period symptoms to unexposed women. The only possible difference was slightly more water retention symptoms in the exposed group. Randomised trial, 1991 Does magnesium supplementation help premenstrual mood changes? Yes, magnesium significantly improved mood-related PMS symptoms and overall PMS scores in women taking it during the premenstrual phase. Survey study, 1991 Does the drug clobazam help with period-related mood and concentration problems? This very small study (11 women) found a general tendency for clobazam to reduce some symptoms in the first half of the cycle, but symptoms seemed to worsen in the second half. Study, 1991 What does the Premenstrual Assessment Form tell us about PMS symptoms? The form helped separate women with PMS from those without, but there was considerable overlap in scores between groups. Fewer than 7% of women with PMS had scores clearly different from the typical range. Randomised trial, 1991 Do antidepressants help premenstrual symptoms in women with depression? Yes. After 12 weeks, at least two-thirds of women taking imipramine or phenelzine had essentially no premenstrual problems, compared to half of those taking placebo. Survey study, 1990 What are the main types of premenstrual symptoms women experience? A study of 702 Dutch women identified four main symptom types: negative mood, concentration problems, pain, and water retention. This shows that psychological symptoms are as important as physical ones in premenstrual syndrome. Cohort study, 1990 What PMS symptoms do women experience even when not seeking treatment? Most women have some premenstrual symptoms. The most common are depressive symptoms (65%), physical discomfort (61.7%), and fluid retention (53.4%). Only 20.3% had no negative symptoms. Survey study, 1989 Is depression that occurs premenstrually different from clinical depression? Yes. Women with PMS experience depressive mood changes premenstrually, but their depression scores are about a third lower than women with clinical depression, and their hormone patterns are also different, showing these are distinct conditions. Randomised trial, 1989 Do oestradiol patches help severe premenstrual symptoms? Yes, oestradiol patches worked better than placebo when women switched from placebo to active treatment. Both groups improved initially, but women who switched from active to placebo got worse, while those who switched from placebo to active maintained or improved their gains. Study, 1988 Are there different types of premenstrual symptoms? Yes. Research found three main patterns of premenstrual changes: hostile-depressive, atypical depressive, and anxious, as well as two less common patterns. Randomised trial, 1986 Does dydrogesterone work better than placebo for premenstrual symptoms? Women in the study improved on most measures, but dydrogesterone did not work better than placebo. Interview study, 1986 In women who report PMS, which symptoms actually follow a monthly pattern? Most women with a history of PMS show typical symptom patterns when tracked daily. Water retention, mood changes, and pain are the most severe symptoms. Survey study, 1985 Are women with PMS mood changes more likely to have depression? Yes, strongly. Women with a depression history are much more likely to have severe PMS mood symptoms, and most women with severe PMS mood symptoms have also had depression at some point. Randomised trial, 1983 Does bromocriptine help severe premenstrual tension? No, bromocriptine did not work better than placebo. Most women improved on both (80% on placebo, 50-88% on bromocriptine), suggesting the improvement may not be from the medication itself. Survey study, 1982 How common are premenstrual symptoms in American women, and what factors affect them? Premenstrual symptoms are very common in American women, with over 30% experiencing weight gain, headache, mood changes, and other symptoms, though only 2% to 8% found them severe. Survey study, 1980 Do thinking and mood symptoms change across the menstrual cycle? Yes. Women report worse concentration, mood, pain, and water retention before and during their period. Patterns vary between individuals. Randomised trial, 1979 Does progesterone help premenstrual syndrome? No. Progesterone at either dose was not significantly better than placebo at reducing symptoms, and placebo was often more effective. Case report, 2026 Can anxiety and PMDD trigger binge drinking, and can medication help? This single case shows that a woman whose binge drinking episodes were triggered by anxiety and linked to her PMDD improved with medication: her anxiety and drinking urges decreased, and she had no new drinking episodes at 12 weeks. Randomised trial, 2026 Is Pilates exercise more effective than stretching for reducing PMS symptoms? Yes. In this small randomized trial of 20 college students with PMS, Pilates was significantly better than stretching exercises at reducing symptoms. Survey study, 2026 Can blood tests help identify which women have moderate-to-severe PMS? Yes. Four blood markers related to inflammation were higher in women with moderate-to-severe PMS compared to mild PMS, and a combined score from these markers predicted moderate-to-severe PMS. Survey study, 2026 Can a yoga program designed for different cycle phases reduce PMS symptoms? Yes. In an 8-week study, 15 women with PMS who did cycle-specific yoga five times per week showed significant decreases in PMS symptoms and improved quality of life, with no adverse effects. Survey study, 2026 Do women with ADHD have worse menstrual, pregnancy, and menopause symptoms? Yes, in this large survey women with ADHD reported significantly more menstrual irregularity, worse premenstrual symptoms, higher postpartum depression, and more severe menopausal symptoms than women without ADHD. Survey study, 2026 Does the menstrual cycle affect how well female athletes perform? Yes. Athletic performance is best after menstruation and after ovulation, with sprint times improving by 7.5% and jump height improving by 5.1% in these phases. Performance drops during the premenstrual phase, with acceleration slowing by 2.3%. Survey study, 2026 Is PMDD linked to sleep problems, diet, and academic stress in female medical students? This study found a clear association between PMDD and poor sleep, and between PMDD and academic burnout in female medical students. However, there was no clear relationship between PMDD and diet. Survey study, 2026 Can homoeopathic medicine treat premenstrual syndrome? In this uncontrolled study, 90% of 30 women showed improvement after individualized homoeopathic treatment over 18 months. Without a comparison group, it is unclear whether improvement was due to the medicine or placebo effect. Non-randomised trial, 2026 Does homeopathic medicine help premenstrual syndrome? In this study of 40 women, homeopathic treatment significantly reduced symptom severity. Because there was no control group, we cannot be sure the improvement came from the medicine rather than from attention, time, or expectation. Survey study, 2026 Are PMDD, anxiety, and internet use linked to cognitive problems in women? In this study of women aged 19-45 with anxiety, those who also had PMDD, severe anxiety lasting 5 or more years, or problematic internet use showed associations with cognitive problems including memory and concentration difficulties. Survey study, 2026 How do PMS, sleep, activity, and weight affect how women feel about their bodies? Women with worse PMS, poorer sleep, higher weight, and more sitting time felt worse about their bodies. These factors worked together, with PMS having an independent effect beyond just weight. Case report, 2026 Does surgery cure PMDD that doesn't respond to medication? In this one woman with severe treatment-resistant PMDD, removal of the uterus and ovaries led to long-term remission of symptoms, though she had severe depression immediately after surgery. We cannot say whether this would work for other women with PMDD. Survey study, 2026 What substances do people use to manage premenstrual symptoms? People most commonly use cannabis, alcohol, and psychedelics to manage premenstrual mood symptoms. People with PMDD use cannabis much more often than others, but we don't yet know how well these substances actually work. Survey study, 2026 Do girls who experienced childhood abuse or neglect have higher PMDD symptoms? Yes. Girls who experienced childhood abuse or neglect reported higher PMDD symptoms compared to girls with limited abuse or neglect. This is a cross-sectional study, so we cannot know if maltreatment causes PMDD. Survey study, 2026 Does controlling personality traits help emotional regulation in women with PMS? The study found that controlling neuroticism (a tendency toward negative emotions) was linked to emotional regulation differently in mild versus moderate PMS. The relationship was complex and depended on PMS severity. Cohort study, 2026 Can one questionnaire help doctors tell the difference between PMS, PMDD, and other mood disorders? Researchers created a new questionnaire called COMPASS designed to help doctors distinguish PMS, PMDD, and perimenopause from conditions like depression, personality disorders, and trauma disorders that cause similar symptoms. Survey study, 2026 Does COVID-19 vaccination cause menstrual cycle changes? Yes, COVID-19 vaccination is associated with changes in PMS symptoms and cycle duration, especially Moderna affecting pain severity. However, this is based on a survey with no control group, so we cannot be certain vaccination directly caused the changes. Review, 2026 Is premenstrual dysphoric disorder now recognized in the international diagnosis system? Yes. ICD-11 now officially recognizes premenstrual dysphoric disorder as a depressive disorder, with seven new specifiers to describe depressive disorders. Specific guidance for children and adolescents still needs more research. Survey study, 2026 Is there a good way to measure menstrual symptoms in teenage girls? Yes. Researchers developed a 12-item scale to measure menstrual symptoms in teenage girls. When different people used it to rate responses, they showed very strong agreement. Systematic review, 2026 How are doctors and researchers diagnosing PMDD differently, and what factors are they using? PMDD is diagnosed inconsistently across research and clinical settings, with some methods relying on patient memory and others on daily tracking. This variation contributes to underdiagnosis and makes research findings harder to compare. Survey study, 2026 Does PMS affect how college students live their daily lives? Yes. About 81% of students had severe PMS, and those with PMS had significantly lower lifestyle quality scores than those without (124 vs 131, p=0.002). Non-randomised trial, 2026 Does high-intensity interval training help women with PMDD? In this study of 35 women with PMDD, 4 weeks of high-intensity interval training significantly reduced symptom severity, pain, and inflammation markers. There was no control group, so we cannot be certain the improvement came from exercise alone. Non-randomised trial, 2026 Does yoga help reduce PMS symptoms? Yes. Yoga significantly reduced PMS symptoms, with 55 to 79% improvement in different symptoms. However, there was no control group for comparison. Non-randomised trial, 2026 Does light resistance training reduce PMS symptoms? Yes. Eight weeks of minimal-dose resistance training reduced both physical and psychological PMS symptoms and functional problems. However, it did not change coping strategies. Randomised trial, 2026 Does Emotion Efficacy Therapy help women with PMDD? Yes. The therapy significantly improved emotional balance, reduced negative automatic thoughts, and reduced impulsive behaviors. The benefits lasted through the two-month follow-up. Study, 2026 Do menstrual tracking apps measure all the symptoms that matter? No. Menstrual tracking apps only captured about half of the common symptoms doctors and researchers know matter, and much less of the mood symptoms that affect women. Survey study, 2026 Does a traditional Chinese herb help PMS? In rats with PMS-like symptoms, Honghua Xiaoyao tablets improved mood-related behaviors and normalized stress hormones. But this is rat research, not human studies, so it cannot tell us if the herb helps real women with PMS. Survey study, 2026 Are there differences in brain activity and connectivity in women with PMDD? Yes, women with PMDD show increased activity in the brain's waste-clearing system (glymphatic system) and increased connections between the hypothalamus and multiple emotion-processing brain regions compared to women without PMDD. Survey study, 2026 How aware are female students of PMDD and how does it affect their schoolwork? Most female students have low awareness of PMDD and rarely discuss it with teachers. PMDD symptoms make it hard to concentrate in class. This was only a survey in Nigeria, so results may not apply elsewhere. Systematic review, 2026 What do we know about PMDD in autistic people and those with ADHD? Very little research exists on PMDD specifically in autistic people and those with ADHD. Early evidence suggests they may experience more severe symptoms and face barriers to diagnosis, but we cannot yet say for certain. Case report, 2026 Can hormonal therapy treat psychotic symptoms tied to the menstrual cycle? This case describes a 26-year-old woman whose psychotic symptoms appeared with her menstrual cycle. Antipsychotic medication initially helped, but low-dose hormonal birth control led to lasting improvement. Non-randomised trial, 2026 Does group counseling reduce PMS symptoms in school students? Yes. Group counseling significantly reduced PMS symptoms across all types (emotional, behavioral, thinking-related, physical) and functional problems. Quality of life improved substantially, and severe school interference dropped from 15.9% to 2.3%. Non-randomised trial, 2026 Are the most bothersome premenstrual symptoms physical or emotional? Emotional symptoms like stress, anxiety, and depression are reported at much higher levels than physical symptoms. Married women experience significantly more emotional distress than unmarried women. Survey study, 2026 What do female students believe causes PMS and what does it affect? Female students strongly believe that hormonal changes and genetic factors cause PMS, and that emotional distress is an effect. However, this measures what students think, not scientific proof. Survey study, 2026 Are PMS and depression connected in nursing students? 38.9% had moderate-to-severe PMS and 12.2% had PMDD. Depression was slightly more common in women with PMS (54.3% vs 47.3%), but this difference was not statistically significant. Survey study, 2026 What are the most common PMS symptoms Egyptian women experience? Physical symptoms like muscle weakness and fast heartbeat are most common, followed by mood changes and depression. Women's age, education, and marital status affect which symptoms they experience. Survey study, 2026 What demographic factors are linked to PMS in middle-aged women? The abstract does not provide specific numerical findings or results. It describes study methods but does not show what demographic factors were actually associated with PMS. Survey study, 2026 Do women with menstrual migraine have worse PMS and PMDD, and does coping strategy affect headache burden? Yes. Women with menstrual migraine had significantly higher PMS severity and PMDD rates than women without menstrual migraine. Using awareness and acceptance coping strategies reduced headache impact on quality of life. Survey study, 2026 How common is PMS in Yemen and what lifestyle factors affect it? About 41.1% had moderate-to-severe PMS. Being overweight, eating fast food, chewing qat, and living in a rural area were linked to worse symptoms. Survey study, 2026 How common is PMS and PMDD in Pakistan and how do they relate to mental health? PMS was found in 36.2% and PMDD in 8.5%. Both were linked to higher stress and depression, and worse quality of life. Survey study, 2026 How common is PMS in female university students in Lebanon and what factors increase the risk? Nearly half (46.8%) had moderate-to-severe PMS and 16.5% had PMDD. Smoking, heavy periods, skipping meals, fast food, social media, and high stress were significantly associated with increased risk. Most women used NSAIDs, but less than half found them very effective. Survey study, 2026 Among women with bipolar I disorder, who is more likely to also have PMDD? About one-third (36.5%) of women with bipolar I disorder have PMDD. Those at higher risk have seasonal mood patterns, a history of suicide attempts, and a family history of mental illness. Survey study, 2026 Do childhood adversity and psychological factors predict how severe PMS is? Yes. Childhood adversity, difficulty expressing emotions, and psychological distress all significantly predict worse PMS. Survey study, 2026 Is PMS or PMDD linked to eating disorders? Yes. Women with PMDD had higher scores for eating disorders, emotional eating, and uncontrolled eating than women without PMS. The link between PMDD and emotional eating was strongest in overweight women. Survey study, 2026 Are poor sleep and high stress linked to worse PMS symptoms in students? Yes, students with poorer sleep and higher stress tended to report more severe PMS symptoms, but this survey cannot prove that stress or poor sleep actually cause PMS. Non-randomised trial, 2026 Does an Ayurvedic treatment called Brahmi Shirodhara reduce PMS mood swings? The treatment showed a 25.3% improvement in overall PMS symptoms. However, this was a very small pilot study with no control group, so we cannot be confident this will work for everyone. Survey study, 2026 How common are PMS and PMDD in young university students? In this group, 7% had PMDD, 46% had mild or no PMS, and 47% had moderate to severe PMS. Students with PMDD had the most severe symptoms and more disruption to daily life. Survey study, 2026 Does childhood trauma cause worse PMS, and does dwelling on negative thoughts explain why? Yes. Childhood trauma directly increases PMS severity, and rumination (dwelling on problems) partially explains this relationship. Survey study, 2026 What factors influence PMS severity in adolescent girls? Mental health is the strongest factor. Girls with higher mental health problems, lower positive beliefs about PMS and fewer enabling resources have more severe PMS. Survey study, 2026 Do trauma and stress worsen PMS symptoms, and does how you think about events matter? Yes. Trauma and stress are strongly linked to worse PMS. The connection may work partly through how women interpret events and how much anger they feel. Survey study, 2026 Does the DSM-5 premenstrual symptom screening tool work for Turkish women? Yes, the tool showed strong performance and accurately separated women by PMS severity. It may be useful for screening PMS according to current diagnostic standards. Survey study, 2026 How common is PMDD in Russian medical students, and what are its symptoms? About 14.3% of medical students had PMDD, or 25.4% including mild forms. Most common symptoms were depression (87.9%), anxiety (48.3%), and sleep problems (31.0%). Survey study, 2026 How do pre-menstrual symptoms affect the work and social life of young women? Pre-menstrual symptoms affect 51.3% of women aged 15-35 with mild-to-moderate PMS and 7.5% with PMDD, significantly disrupting work and social activities. The severity of symptoms directly predicts how much they interfere with daily life. Survey study, 2025 How common are PMS and PMDD among female university students? About 10.37% had PMS and 19.26% had PMDD. Technical course students had higher rates than medical course students. Survey study, 2025 What diet and lifestyle habits increase PMS risk in college students? Eating cake, pastries, and pizza frequently, using contraceptive pills, and sleeping only 5-6 hours on weekdays were all linked to higher PMS risk. About half of the students had PMS. Survey study, 2025 Does PMS affect thinking ability, sleep quality, and attention in teenage girls? Yes. Teenage girls with PMS had lower scores on thinking tests, worse sleep quality, and a shorter Stroop effect duration than girls without PMS. Cohort study, 2025 Does worse PMS pain and concentration problems affect a woman's balance during her cycle? Yes. Women with more pain and concentration problems during menstruation had poorer balance. Women with worse overall symptoms before their period also had poorer balance, though the study was very small with no comparison group. Interview study, 2025 Does sleep quality affect how severe PMS symptoms are? Yes. Poor sleep was linked to more severe PMS symptoms, including anger, anxiety, mood changes, and fatigue. Survey study, 2025 Are PMDD symptoms linked to depression and anxiety? Yes. Women with higher PMDD-type symptom scores were much more likely to have depression and anxiety, and most women with PMDD had severe depression and moderate-to-high anxiety. Survey study, 2025 How many university students have PMDD and do they know about it? About 4 in 10 university students in Riyadh met PMDD criteria. Most (58.5%) had heard of PMDD before.

In this pilot study, fenugreek reduced PMS symptom scores by an average of 32% and was well tolerated. However, there was no control group, so the improvement could be due to placebo effect. Non-randomised trial, 2025 Does acupressure help relieve PMS symptoms? Acupressure reduced PMS symptom severity and improved ability to function in nursing students. The study did not have a control group and reported results qualitatively, so we cannot be very confident about how much improvement occurred. Non-randomised trial, 2025 Does aerobic exercise reduce anxiety and depression in students with PMS? Yes, female students who did aerobic exercise showed large reductions in both anxiety and depression. However, there was no control group that did not exercise, so we cannot be certain the exercise caused the improvement rather than placebo or natural variation.

As PMS increased, physical activity decreased, appetite increased, and women preferred emotionally comforting foods and evening hours. Case-control study, 2025 Do certain hormone-related brain chemicals predict how bad premenstrual depression and anxiety will be? In this small study, women with a PMDD-like condition had higher levels of a calming hormone (allopregnanolone) early in the cycle, and higher levels of it predicted worse later depression and anxiety. The sample is small, so this is an early finding, not a proven cause. Cohort study, 2025 Do women with PMS have more nightmares before their period, and does nightmare therapy help? In this very small study, women with PMS showed more frequent nightmares in the premenstrual phase. Nightmare therapy improved overall severity, but the benefit in PMS women specifically was unclear.

Processed food consumption was not significantly associated with PMS. This was an observational study so we cannot prove stress causes worse PMS. Non-randomised trial, 2024 Does PMS education and medical help reduce symptoms and improve work performance? Medical help reduced one type of symptom (intermenstrual symptoms) in women with moderate-to-severe PMS, but did not clearly improve other symptoms or work productivity. Very few women sought help despite education. Survey study, 2024 Does diet or exercise affect PMS symptoms? In this study of women in India, there was no link between PMS and junk food, physical activity, sugar, salt, or citrus fruits. This is one small study in one city, so it may not apply to all women. Survey study, 2024 Do teenage girls in cities have more PMS than girls in the countryside? Yes, PMS was more common and more severe in teenage girls in urban areas compared to rural areas in India. This is one regional study though, so it may not apply everywhere. Lab study, 2024 Does the yoga pose Baddha Konasana help PMDD? No clear difference. Although symptoms decreased somewhat from the first to the second menstrual cycle, the improvement was not large enough to confirm that the yoga pose helps. Non-randomised trial, 2024 Do Pilates exercises and WhatsApp support reduce PMS and improve daily activities and academic performance? Yes, significantly. Students showed decreased PMS, improved daily activities, and better academic performance with highly statistically significant improvements at 4 and 8 weeks.

The study was very small and needs larger follow-up studies. Survey study, 2024 Does childhood abuse increase premenstrual syndrome through suicidal thoughts? Yes. Women who experienced childhood abuse were more likely to have PMS, partly through increased suicidal thoughts. Different types of abuse had slightly different patterns. Survey study, 2024 What symptoms and life factors are most closely linked to PMS in young women? Anxiety showed up as the symptom most tightly connected to everything else in PMS, closely tied to low mood, and PMS was also linked to a history of painful periods and a neurotic personality type. This comes from one pattern-mapping study, not a trial, so it cannot prove what causes what. Survey study, 2024 Does asthma get worse around your period in teenagers? Yes, 75.5% of teenage girls with asthma reported their symptoms worsened around their period. This was a small study with no comparison group, so we cannot be completely certain.

Survey study, 2021 How common are PMS and PMDD in young Turkish women? PMS affects 26.1% to 61.1% and PMDD affects 10.0% to 20.4% depending on diagnostic criteria used. Anger and irritability are the most common PMDD symptoms at 97.4%. Survey study, 2021 What is the prevalence of PMDD and how does it affect quality of life in female students? About 4.43% of female students had PMDD. Those with PMDD had significantly lower quality of life, especially in social relationships and at work. The evidence is clear for this group, but the study only included students in India. Survey study, 2021 Does PMS affect sexual function during the menstrual cycle? No, PMS does not affect sexual function. Sexual function was worse during the luteal phase regardless of whether women had PMS. Survey study, 2021 Does premenstrual tension syndrome affect how well a woman's family functions? Yes, in this study premenstrual tension syndrome was very common among female university students, and the more severe it was, the more likely their family was to be dysfunctional. Survey study, 2021 How common are premenstrual symptoms in female medical students, and how severe are they? About 30% have premenstrual symptoms, mostly mild. Psychological symptoms like irritability are more common than physical ones. Survey study, 2021 Do women with PMS have real trouble with focus and memory, or just feel like they do? Women with PMS report problems with focus, memory, and organization, and these self-reported problems are strongly linked to PMS symptoms. However, when tested on actual focus and memory tasks, they do not perform noticeably worse. Survey study, 2021 Do PMS and PMDD affect attention and short-term memory in teenage girls? Yes, somewhat. Teenage girls with PMS/PMDD did worse on a test of attention and interference control than girls without it, and their performance dropped further in the luteal (premenstrual) phase. Survey study, 2020 How common is premenstrual syndrome in young females? The study does not report the exact prevalence percentage. It confirms that PMS symptoms are common in young women and often limit their daily activities. Survey study, 2020 How do diet and lifestyle factors relate to PMS and PMDD in medical students? Alcohol and tobacco use were linked to PMDD. Diet type was not linked to PMS or PMDD. Anger and irritability were the most common symptoms. Survey study, 2020 Does a history of childhood trauma make premenstrual symptoms worse? Yes, women who reported more childhood trauma also reported more severe premenstrual symptoms, and this link seemed to be fully explained by difficulties managing emotions. Survey study, 2020 Can the PSST reliably diagnose PMDD? Yes. PSST scores of 1.5 to 3 reliably identify women with PMDD, helping doctors recognize who needs immediate treatment instead of waiting. Survey study, 2020 Is the Japanese version of the DRSP a reliable tool for tracking PMS? Yes. The Japanese DRSP is reliable and valid for tracking symptoms and diagnosing PMS in Japanese women, with very strong internal consistency. Randomised trial, 2020 Does walking reduce stress and symptoms in PMS? Walking plus breathing exercises reduced breathing rate and abdominal pain compared to breathing exercises alone, but overall PMS symptom improvement was similar between groups. Survey study, 2020 Do past trauma and emotions predict PMS severity? Yes. How women cope emotionally, particularly catastrophizing (assuming the worst), predicted about one-third of PMS severity. Past trauma involving life threat also predicted about one-third of PMS severity. Survey study, 2020 Does diet affect PMS symptoms in teenage girls? Girls who ate more carbohydrates had fewer PMS symptoms. Body fat percentage was not linked to PMS symptoms. The study was observational, so higher carbohydrate intake may not directly cause fewer PMS symptoms. Survey study, 2020 How common is PMDD among female health science students in Ethiopia, and what is linked to it? About 1 in 3 students in this study had PMDD. It was more common among those with severe period pain, with high stress, and those who felt their period pain hurt their studies. Survey study, 2020 How common is premenstrual syndrome in Korean young adult women? Between 22 and 42 percent of Korean nursing students had PMS, depending on whether they reported from memory or tracked symptoms in real-time. Survey study, 2020 Do women with IBS and period problems have worse psychological symptoms? Yes. Women with IBS alongside period pain and PMS show more depression, sleep problems, and worse quality of life than those without IBS. Survey study, 2020 How common are PMS and PMDD in women with mood and anxiety disorders? PMS affected 47.5% and PMDD affected 13.0% of women with mood or anxiety disorders. Both were significantly linked to diet, menstrual patterns, and medication use. Survey study, 2020 How common is PMS in elite female athletes, and do training or lifestyle factors cause it? 14.55% of elite female athletes have moderate to severe PMS. No specific modifiable risk factors were found. 76.6% of athletes felt their symptoms interfered with performance, but only 5 out of 18 athletes with PMS saw a doctor. Case report, 2020 How do psychotic symptoms connected to the menstrual cycle look in different parts of the world? In a study of 4 women in Oman with menstrual psychosis, all had psychotic and mood symptoms timed to their menstrual cycle. All had normal intelligence but had problems with thinking speed, memory, and planning skills. Cohort study, 2020 Are immune and oxidative stress markers linked to menstrual cycle symptoms? Certain markers related to antioxidant defenses and immune function may play a role in menstrual cycle symptoms, though this isn't due to general inflammation. However, this is a small study with no control group, so the findings need confirmation. Survey study, 2020 Is there a biological cause for menstrual cycle symptoms? Yes. Women with menstrual cycle symptoms had higher levels of certain immune proteins called chemokines. One protein called CCL2 explained a significant portion of the symptom severity. Survey study, 2020 Can teaching about PMS management improve girls' knowledge? Yes. Before teaching, all girls had below-average knowledge about managing PMS. After the teaching program, most girls had average or good knowledge. Survey study, 2020 How is premenstrual dysphoric disorder different from premenstrual syndrome, and what treatment helps? PMDD is more severe than PMS and causes real disability in daily life, affecting fewer women. SSRIs are described as working well, sometimes with progestogens added. This is based on one patient case and a review of past research, not a trial, so certainty is low. Survey study, 2019 Are PMS symptoms linked to how women feel about their health and stress? Yes. Women who reported feeling unhealthy or stressed had much more severe PMS symptoms. How a woman perceives her own health was the strongest factor linked to PMS symptom severity. Survey study, 2019 Are teen girls with depression or PMS/PMDD more likely to act aggressively? Yes. Girls with a depressive mood or a PMS/PMDD diagnosis showed more aggression than other girls, but this snapshot-style study cannot prove that depression or PMS/PMDD causes the aggression. Survey study, 2019 What is the best way to diagnose PMS using blood tests and symptom patterns? A new diagnostic method called MCAS combines daily symptom tracking with blood tests for hormones and immune markers. This method was validated by multiple blood biomarkers and performed better than standard diagnostic criteria. Survey study, 2019 Are suicide attempts more common during certain phases of the menstrual cycle? Yes, 59% of suicide attempts occurred during the last 4 days of the luteal phase and during the 4 days of menses. However, the study could not explain why, since no depression, aggression, or other psychiatric features measured were related to this timing. Study, 2019 Does 8 weeks of aerobic exercise reduce PMS symptoms? Yes, aerobic exercise for 8 weeks reduced both psychological and physical PMS symptoms with a clear difference between before and after. Survey study, 2019 Do low progesterone levels cause PMS symptoms? Yes. Women with lower progesterone levels overall, and those whose progesterone dropped more during the two weeks after ovulation, had worse PMS symptoms. Estradiol was also linked to PMS but this effect was largely explained by progesterone levels. Survey study, 2019 Does the Arabic version of the Premenstrual Screening Tool accurately diagnose PMDD? The Arabic screening tool correctly identified women without PMDD but missed many who had it. It had high specificity (95.6%) but low sensitivity (26.7%), so it can still be useful in primary care settings but needs improvement. Cohort study, 2019 Is there a link between menstrual symptoms and anxiety, depression, and stress in teenage girls? Yes. There was a strong correlation between menstrual distress and depression, anxiety, and stress, with distress significantly higher before, during, and after menstruation (p=0.000). Case-control study, 2019 Do brain regions connect differently in women with PMS? Yes. Women with PMS show different patterns of brain connectivity between the thalamus and the prefrontal cortex compared to women without PMS. Survey study, 2019 Does the menstrual cycle affect gut bacteria and immune response related to PMS? Yes. Antibody levels to gut bacteria change throughout the cycle, peaking at day 28, and these changes are linked to physical symptoms like bloating, anxiety, and breast swelling but not depression. Progesterone appears to drive these changes. Survey study, 2019 How common is PMS in female operating room technologists? The study aimed to find how common PMS is in female operating room technologists and what factors influence it, but the results are not provided in this abstract. Case-control study, 2019 Do women with sickle cell disease have more severe PMS symptoms than other women? Women with sickle cell disease had similar rates and severity of PMS as healthy women (68% versus 78%). However, they showed lower depression scores related to PMS, possibly because they are accustomed to more severe chronic pain. Survey study, 2018 How common are PMS and PMDD among medical students in South India? Of 635 medical students surveyed, 177 had PMS and 88 had PMDD. The most common symptoms were anger or irritability, feeling tearful or overly sensitive, and fatigue or lack of energy. Systematic review, 2018 Does acupuncture or acupressure help PMS symptoms? Acupuncture may reduce mood-related PMS symptoms more than sham acupuncture, but the evidence is very weak due to small studies with design problems. We cannot be confident it works. Case-control study, 2018 Do women with PMS have different brain structures than healthy women? Yes. Women with PMS had larger brain volumes in two areas and smaller volume in one area compared to healthy controls. However, this is based on a very small study with only 20 women per group. Case-control study, 2018 Are there differences in brain thickness and volume in women with PMS? Yes. Women with PMS had thinner cortex in three brain areas and larger volumes in three deeper brain structures. These relate to emotion and sensation, but this small study needs replication. Survey study, 2018 What is PMDD and how common is it? PMDD is a serious form of premenstrual distress affecting 1.8 to 5.8 percent of women who menstruate. It is officially recognized as a psychiatric condition, though the exact cause is still being researched. Randomised trial, 2018 Does an oral contraceptive with drospirenone reduce premenstrual worsening of Meniere's disease? Yes. The oral contraceptive combined with rehabilitation significantly improved dizziness and balance over 6 months, with the contraceptive group showing much better symptom improvement than rehabilitation alone. Survey study, 2018 Can a questionnaire predict which homeopathic medicine helps PMS? Yes, a questionnaire with a computer algorithm reliably ranked 11 homeopathic medicines for PMS based on a woman's specific symptoms, though this does not prove the medicines actually work. Cohort study, 2018 Is brain activity different in women with PMS, particularly in the hippocampus? Women with PMS show increased left hippocampus activity and stronger connections between this region and emotion-processing areas. The connection strength correlates with symptom severity, suggesting abnormal brain activity may play a role in PMS. Survey study, 2018 Do women who attempt suicide experience more menstruation-related problems? More than half of women who attempted suicide reported premenstrual distress symptoms for two menstrual cycles. The study cannot prove menstrual problems caused suicide attempts, but suggests a possible connection. Survey study, 2018 How does PMS affect self-esteem in girls? Girls with PMS showed lower self-esteem compared to expected levels. The link may be because PMS mood changes lead girls to feel worse about themselves. Survey study, 2018 Do women with PMS really experience mood and behavior changes linked to their menstrual cycle? No. This small study found no evidence of mood or behavior changes linked to the menstrual cycle, suggesting retrospective questionnaires may overestimate PMS. Cohort study, 2018 Do emotional and behavioral symptoms of borderline personality disorder get worse before menstruation? Most emotional symptoms appeared to get worse in the middle-to-late luteal phase and around menstruation, then improved in the follicular phase. However, the study was very small and included only unmedicated women without painful periods. Survey study, 2018 Do the PSST and DRSP questionnaires give the same PMS diagnosis? No, the two questionnaires gave very different results with poor agreement. The PSST is best used as a screening tool to identify possible cases that then need confirmation with the more thorough DRSP. Survey study, 2018 Does using a smartphone app help PMS symptoms as much as visiting a doctor in person? Using a smartphone app worked about as well as visiting a doctor for PMS, and women using the app were more satisfied with their care. Survey study, 2018 Does premenstrual syndrome increase stress in nursing students? Yes. Women nursing students with PMS had significantly higher stress levels than those without PMS. Survey study, 2018 Does cognitive behavioral therapy with calcium and vitamin D help PMS symptoms? Yes, women who received cognitive behavioral therapy with calcium and vitamin D showed significant improvements in PMS symptoms compared to those who did not receive treatment. Survey study, 2017 Can a symptom diary distinguish between PMS and PMDD? Yes, researchers developed scoring systems for symptom diaries that reliably distinguished between PMS and PMDD and correlated well with other assessments. Survey study, 2017 Do women with PMS have different brain activity than other women? Yes, women with PMS show different brain activity than other women. The study is small (only 20 women with PMS), so larger studies are needed to confirm these findings. Cohort study, 2017 Are there differences in spontaneous brain activity between women with PMS and healthy women? Women with PMS show abnormal patterns of brain activity during the luteal phase, with overactivity in some regions and underactivity in others. These differences correlate with symptom severity, suggesting altered brain function is involved in PMS. Survey study, 2017 How common are PMS symptoms in university students and do they disrupt daily life? PMS is very common, with more than three-quarters of students experiencing some symptoms, and many had symptoms severe enough to interrupt their daily activities. Case report, 2017 Does Ayurvedic medicine help PMS? Yes. One 18-year-old woman's mood swings, irritability, and concentration problems were completely relieved after one month of Ayurvedic herbs and weekly therapy sessions. Randomised trial, 2017 Do kinesio taping and hot packs reduce premenstrual syndrome symptoms? Yes, kinesio taping alone and combined with hot packs both reduced PMS symptoms in women in their 20s. Survey study, 2017 What factors make PMS symptoms worse in college-aged women? Older age, low family income, being unmarried, and family history of PMS or painful periods are all linked to more severe PMS. Survey study, 2017 Does malaria infection worsen PMS symptoms? This was the first study to examine whether malaria parasites affect PMS. It found that students with PMS and malaria parasites had lower red blood cell levels, but it cannot prove parasites cause worse PMS. Survey study, 2017 Are PMS symptoms linked to mood disorders and personality? This study found significant relationships between PMS symptoms and lifelong mania or hypomania symptoms, and between PMS and personality traits. Because it was cross-sectional, we cannot know if hormonal changes in PMS cause mood and personality changes. Survey study, 2017 How common is migraine in women with PMS? About 1 in 7 medical students with PMS also had migraines. Most migraines occurred without visual symptoms and happened about 4 times per month. Results may not apply to all women since this studied only medical students. Survey study, 2017 Can we detect differences in how women's brains work during different parts of the menstrual cycle? Yes. Brain activity patterns are different during menstruation, the follicular phase, and the luteal phase, with 72-93% accuracy in detecting these differences depending on which phases are compared. Survey study, 2017 Is fibromyalgia more common in women with PMS, and does it affect quality of life? Yes. Fibromyalgia was present in 20% of women with PMS versus 0% of healthy controls, and the combination seriously reduces both mental and physical quality of life. Study, 2017 Does what women eat affect how severe their premenstrual symptoms are? Yes. Women with severe premenstrual tension symptoms ate different amounts of certain nutrients compared to women with mild symptoms. Women with severe symptoms ate significantly more fat and vitamin C. Randomised trial, 2017 Does adding birth control to antidepressants help depression that worsens before your period? Adding drospirenone/ethinyl estradiol to antidepressants did not significantly improve premenstrual depression better than placebo in this small study. Both groups improved similarly. Survey study, 2016 How common are PMS and PMDD among women in Myanmar? 37.3% of the women met criteria for PMS, and 54.4% of those had PMDD. The study included only women in medicine, so these numbers may not represent all women. Case-control study, 2016 Do women with major depression or bipolar disorder experience more premenstrual symptoms than healthy women? Women with major depression in remission had more PMS than healthy women, with higher scores for depressive mood, anger, and other symptoms. Women with bipolar disorder in remission had similar PMS rates to healthy women. Randomised trial, 2016 Does Gung massage reduce PMS symptoms better than other treatments? Gung massage reduced more PMS symptoms than heat or regular massage. All treatments reduced pain, but Gung massage had the largest improvements in pain, emotions, water retention, and body temperature after 8 weeks. Non-randomised trial, 2016 Does a low-dose birth control pill help with menstrual pain in women with endometriosis? Yes. A birth control pill containing drospirenone and ethinylestradiol significantly reduced menstrual pain, pelvic pain, pain with sex, and premenstrual bloating and mood symptoms. The study had no control group, so we cannot be completely certain the improvement was from the pill. Cohort study, 2016 Do women with PMDD have more difficulty controlling their emotions? Yes. Women with PMDD reported significantly more trouble controlling emotions and more impulsive behavior than healthy women. Cognitive and behavioral strategies might help, but this finding is based on a small study. Survey study, 2016 Do women with PMDD have more difficulty regulating their emotions? Yes. Women with PMDD and PMS had significantly more difficulty with emotional regulation compared to controls, especially those with psychological symptoms. Survey study, 2016 Can we reliably measure how much PMS interferes with a woman's daily life? Yes. Researchers created an 18-item questionnaire that reliably measures both emotional and daily life effects of PMS, with good reliability (Cronbach's alpha 0.90 for both subscales) confirmed in 101 women. Interview study, 2016 How common are PMS and PMDD among college students in India? PMS was found in 18.4% of college students and PMDD in 3.7%. A simple screening questionnaire was 90.9% effective at identifying women with PMS. Non-randomised trial, 2016 Does a birth control pill improve quality of life in women with moderate to severe PMS? Yes, this pill significantly improved quality of life in multiple areas after 3 months, with 88.4% of women reporting satisfaction with treatment. However, this was a small study with no comparison to other treatments. Survey study, 2016 Does PMDD cause sleep problems? Yes. Women with PMDD have significantly worse sleep quality than those without, with 80.5% reporting poor sleep compared to 56.4% without PMDD. Survey study, 2016 Can a computer program help diagnose PMDD reliably? Researchers developed C-PASS, a computer system to help diagnose PMDD from daily symptom tracking. The abstract was incomplete and did not include results of how well it works. Case-control study, 2016 Is low vitamin D related to PMS? No. Although vitamin D deficiency was common in both groups of young Iranian women, there was no difference in vitamin D levels between those with PMS and those without. Non-randomised trial, 2015 Does this birth control pill help premenstrual symptoms in Japanese women? Yes, in this study of 48 Japanese women, most premenstrual symptoms improved significantly after 3 and 6 cycles of treatment. The study had no comparison group, so we cannot be fully certain of the effect. Survey study, 2015 Does isoflavone supplement help with premenstrual syndrome and period pain? Isoflavone supplement at 500 mg per day improved several PMS symptoms including mood, concentration, pain, and water retention after 8 weeks, compared to no improvement in women who didn't take it. However, the study was very small with only 10 women in each group. Interview study, 2015 What are the symptoms of PMDD and how many women have it? PMDD is a severe form of premenstrual syndrome. About 90% of women experience premenstrual symptoms, but only 4.6% to 6.4% meet criteria for PMDD, and about 5% experience severe symptoms. Study, 2015 Should premenstrual dysphoric disorder be classified as a mental illness? A bioethicist argues PMDD should not be classified as a psychiatric disorder because doing so pathologizes normal anger and distress. This is a philosophical perspective, not based on a research study. Survey study, 2015 How common is PMDD in Indian medical students and what lifestyle factors affect it? PMDD was found in 37% of medical students and was linked to poor sleep, low physical activity, and high caffeine intake. Study, 2015 How should PMDD be treated? Women with PMDD should receive medication treatment if correctly diagnosed. Accurate diagnosis using standard criteria is essential, and treatment should be given by experienced psychiatrists to distinguish PMDD from regular PMS. Survey study, 2015 How common is PMS in medical students and does it affect quality of life? About 39.4% of female medical students had PMS. Women with PMS reported significantly lower quality of life scores in mental health and environmental health compared to those without PMS. Survey study, 2015 Which screening tool is best for diagnosing PMDD and menstrual-related psychiatric conditions? There is no agreed-upon best tool. Different studies use different definitions and methods, making it hard to compare research and provide consistent care. Non-randomised trial, 2015 Does daily meditation with classical music reduce PMS symptoms? Yes, practicing 15-minute meditation with music every day significantly reduced PMS symptoms across all measured areas over one menstrual cycle. However, the study was small and had no control group. Study, 2014 How did PMDD become an official diagnosis? PMDD was officially added to the DSM-5 with little controversy, unlike earlier proposals. Interviews revealed that changes in scientific evidence and professional attitudes led to acceptance. Survey study, 2014 Should PMDD be included as an official diagnosis in psychiatric manuals? The authors argue yes, because evidence confirms PMDD exists, affects a minority of women, and exists worldwide. Making it official allows affected women to receive proper recognition and treatment. Survey study, 2014 Is PMS linked to difficulty identifying and describing emotions? Women with PMS scored higher on measures of alexithymia, which means difficulty recognizing and expressing emotions. The study could not determine whether this causes PMS or results from it. Survey study, 2014 Does Baduanjin, a traditional Chinese exercise, reduce PMS symptoms? Yes, women who practiced Baduanjin for three menstrual cycles showed significant reductions in both physical and emotional PMS symptoms. Survey study, 2014 Does how much girls exercise affect their PMS symptoms? Yes, there was a clear difference in PMS symptoms between girls with different activity levels. Girls with health-enhancing physical activity had higher symptom scores than the overall average. Survey study, 2014 Do brain wave patterns change at different times of the menstrual cycle? Yes, brain wave patterns changed significantly across the menstrual cycle. The luteal phase (second half) showed the strongest overall brain wave activity, while the follicular phase (first half) showed a different type of brain activation. Survey study, 2014 Do brain wave patterns change at different times of the menstrual cycle? Yes, brain wave patterns changed significantly across the menstrual cycle. The luteal phase (second half) showed the strongest overall brain wave activity, while the follicular phase (first half) showed a different type of brain activation. Study, 2014 Does the oral contraceptive Marvelon help with PMS symptoms? Yes. When women took Marvelon (a combination birth control pill) for 6 months, their PMS symptoms got noticeably better. Other measures of health including blood cholesterol also improved. Case-control study, 2014 Are appetite-regulating hormones ghrelin and leptin different in women with PMS? Leptin levels were higher in women with PMS before their period, but ghrelin showed no difference. The meaning is unclear because these hormones normally work together to control hunger. Study, 2014 What symptoms do women experience before and during their period, and what makes them worse? Tension and breast tenderness are common before the period, while cramps and back pain are common during it. Working, smoking, heavy tea or coffee drinking, and relationship stress are linked with worse symptoms. Survey study, 2014 What does Asian research show about premenstrual dysphoric disorder? Most research from Asia on PMDD has been prevalence studies documenting how common it is. Asian research on the genetic and biological basis of PMDD remains very limited. Survey study, 2014 How common is PMS among university women and how does it affect their schooling? 37 percent of female students met diagnostic criteria for PMS. About 28 percent missed classes because of PMS, and most did not seek medical treatment. Survey study, 2013 Does smoking behavior change across the menstrual cycle and is it linked to mood and period symptoms? Yes. Young women smokers smoked more cigarettes and had stronger cravings during the luteal phase (second half of the cycle). Smoking was linked to higher depression and menstrual symptoms, but the study cannot prove smoking causes these or vice versa. Survey study, 2013 Is a daily symptom tracker reliable for measuring PMS in Chinese women? Yes. The Daily Record of Severity of Problems showed good reliability and validity for tracking PMS symptoms in Chinese women, with stable measurements across two cycles. Survey study, 2013 What are the clinical subtypes of premenstrual disorders? Experts classify PMS into three types: predominantly physical, predominantly psychological, and mixed. Some women with the psychological or mixed types also meet criteria for PMDD. Survey study, 2013 Do women with PMDD have different brain activity related to depression during their menstrual cycle? Yes, women with PMDD show different brain activity related to depression during the luteal phase compared to women without PMDD. The study is small and needs confirmation in larger groups. Survey study, 2013 Are premenstrual symptoms linked to how women experience their body? Yes. Women with premenstrual symptoms tend to focus more on physical sensations in their body, and this may contribute to how severe their symptoms become. Survey study, 2013 How many college students have premenstrual symptoms? Most do. 90 percent of college students report at least one premenstrual symptom, but only a few with severe symptoms seek help. Study, 2013 Do women with PMS experience more mental health symptoms? Yes, the study found that women with PMS had connections to various mental health symptoms including depression, anxiety, anger, and others. Survey study, 2013 Is PMS linked to perfectionism and anxiety in college students? Yes, but the link differs by student type. In nursing students, PMS is linked to both perfectionism and anxiety. In general students, it is only linked to anxiety. Survey study, 2012 Can a saliva test show menstrual stress? Possibly. The study found that levels of progesterone and amylase in saliva showed a relationship with menstrual distress and premenstrual symptoms, suggesting saliva tests might be useful for tracking menstrual stress. Survey study, 2012 Do premenstrual disorders lower teenage girls' quality of life? Yes. In this Iranian study, teenage girls who met the criteria for PMDD had worse quality of life than those who did not, across almost every area measured. Interview study, 2012 Should PMDD be recognized as a real mental health diagnosis? Yes, research has grown enough to support PMDD as a full diagnostic category in the DSM-5, which should increase treatment options and research. Survey study, 2012 Is there a link between attitudes toward menstruation and PMS symptoms? Women with PMS symptoms were more likely to see menstruation as debilitating. This shows correlation but does not prove that attitudes cause worse symptoms. Case-control study, 2012 Is the German screening test for premenstrual symptoms reliable and valid? Yes. The SIPS screening test is reliable and valid and appears to help identify women who need treatment for premenstrual symptoms. Non-randomised trial, 2011 Can a procedure for heavy periods also improve PMS symptoms? In this small study, women who had an endometrial ablation (NovaSure) for heavy periods saw their PMS symptoms improve a lot too, but there was no comparison group so we cannot be fully sure the procedure itself caused it. Survey study, 2011 Do women with severe PMS have more personality disorders? Yes. 27% of women with severe PMS had a personality disorder compared to 0% of women without PMS. The most common was obsessive-compulsive personality disorder. Survey study, 2011 How common is severe PMS or PMDD in teenage girls, and what does it look like? Almost 3 in 10 girls screened positive for severe PMS or PMDD, with irritability being the most common symptom, and the pattern looked similar to what is seen in adult women. Survey study, 2011 Can premenstrual symptom rating scales be simplified and made easier to use? Yes. Researchers updated the rating scales and created a new visual scale that women found easier to use, especially those with severe PMS or PMDD. Survey study, 2011 Does work stress and night shifts increase risk of PMS and PMDD? Yes, women working night shifts had higher rates of PMS (56% vs 32%) and PMDD (22% vs 13%) compared to women without shift work, but we cannot prove the shifts caused these conditions. Survey study, 2010 How should doctors diagnose PMS and PMDD? Doctors should use symptom diaries and other proven diagnostic tools to distinguish PMS and PMDD from other conditions, though many overlapping symptoms make diagnosis challenging. Cohort study, 2010 How do anxiety disorders differ across different life stages? The provided summary focuses on anxiety in children and risk factors. The section about women and hormones is cut off in the provided text, so no conclusion about menstrual-related anxiety can be drawn. Study, 2010 Which PMDD medication is most cost-effective? This analysis suggests the birth control pill DRSP/EE may be the most cost-effective option for PMDD treatment, though fluoxetine could be cost-effective depending on how much someone is willing to spend. Survey study, 2010 Do women with PMS or PMDD miss more work? Yes. Women with moderate-to-severe PMS or PMDD reported more days with reduced work productivity (5.6 days per cycle vs 1.1) and higher rates of missing work (14.2% vs 6.0%). Review, 2010 Does the EE/DRSP birth control pill with shorter placebo days reduce PMS symptoms? The EE/DRSP pill with 24 days of hormones and 4 days of placebo appears to reduce PMS and withdrawal symptoms including mood changes, breast tenderness, headache and pelvic pain. The evidence comes from clinical trials but specific numbers of improvement are not given. Survey study, 2010 How many Greek nursing students have PMS or PMDD? Among 101 Greek nursing students who completed the study, 25.7% had PMS and 8.9% had PMDD. Survey study, 2010 How common is PMDD among medical students in Nigeria? 36.1% of medical students had PMDD. Menstrual pain was significantly linked to PMDD. Survey study, 2010 How common are premenstrual symptoms in women around age 40? About 38% of women around age 40 had three or more premenstrual symptoms, and about 4.7% reported them as severe. Non-randomised trial, 2010 Does a birth control pill with drospirenone improve severe PMS or PMDD? Yes. Symptom scores dropped dramatically from an average of 24.6 to 7.2 after 3 to 4 months of treatment, with significant improvement in women whether or not they had used contraception before. Randomised trial, 2009 Does duloxetine help treat premenstrual dysphoric disorder? Yes. 65% of the 20 women improved by at least 50%, with statistically significant overall symptom reduction. However, this was a small uncontrolled pilot study, so larger research is needed to confirm results. Study, 2009 Can the standard mental health diagnostic interview assess PMS and PMDD adequately? No. The standard interview does not assess PMS, PMDD, or other women-specific mental health conditions. New diagnostic modules were developed to address this gap. Cohort study, 2008 How can menstrual-related irritability be measured reliably? Researchers developed two rating scales for measuring menstrual-related irritability. Both the 14-item self-report and 5-item observer scales showed strong reliability and consistency. Survey study, 2008 Do the diagnostic criteria for PMDD correctly identify who has the condition? 20% of women met the diagnostic criteria for PMDD in this study, but 4% of men also met criteria when given the same forms, and people with psychological distress did not necessarily meet the criteria, suggesting the criteria may not be valid. Survey study, 2008 Does eating lower glycemic index carbohydrates help reduce PMS symptoms? Yes. Lower glycemic index diet was associated with fewer overall PMS symptoms and specifically with fewer concentration problems, autonomic reactions, and water retention. Randomised trial, 2008 Does levetiracetam help treat PMDD? In a small pilot study, 6 out of 7 women with PMDD had their symptoms improve considerably with levetiracetam over 4 months. Because there was no control group, we cannot be sure the improvement was due to the drug rather than other factors. Survey study, 2008 Do severe physical symptoms during the menstrual cycle mean a woman will also have worse mood problems? No. Women with severe physical symptoms in the late menstrual cycle phase did not have worse overall psychological symptoms than those without physical symptoms. Only one psychological measure (interpersonal sensitivity) differed. Survey study, 2008 Do healthy women without PMDD have mood changes during their menstrual cycle? Yes, but the changes are small. Healthy women without PMDD showed small increases in anxiety, depression, and other negative mood symptoms from late follicular to late luteal phase. Survey study, 2008 Has the definition of PMS changed over time in different countries? Yes, significantly. The understanding of PMS has changed from hormonal theories to psychiatric ones, and doctors in different countries have used different diagnostic approaches. There is still disagreement about whether PMDD (severe PMS) belongs in psychiatric manuals. Study, 2008 Does YAZ birth control help PMDD symptoms? FDA has approved YAZ for treating PMDD, and two studies showed it helps mood, physical, and behavior symptoms plus symptoms related to food cravings, water retention, and relationship difficulties. Guideline, 2007 What are the diagnostic criteria for PMS and PMDD? An international group of experts developed updated diagnostic criteria and guidelines for PMS and PMDD to help doctors and researchers diagnose these conditions consistently. Non-randomised trial, 2007 Does a 50% drop in PMS symptom scores matter in real life, like fewer doctor visits or costs? Yes. Women with much higher premenstrual symptom scores had notably more doctor visits and medical costs, which supports using a 50% symptom reduction as a meaningful marker of improvement in PMS or PMDD treatment studies. Non-randomised trial, 2007 Can a birth control pill with ethinylestradiol and drospirenone reduce water retention in PMS? The pill significantly reduced total body water and extracellular water after 6 months. This was a small study without a placebo control, so we cannot be certain the improvement was due to the pill. Survey study, 2007 How common and how recognised is PMDD among young women? In this small study of Croatian students, 15 out of 87 women had PMDD, suggesting it may be more common than usually recognised, but this is from one small sample so it cannot tell us the true rate everywhere. Survey study, 2007 Is pain sensitivity different in people with severe PMS? People with high PMS had significantly lower pain sensitivity at one specific acupuncture point (SP6) but not at other points tested. This suggests a connection between PMS and pain sensitivity. Randomised trial, 2007 Do birth control pills help depression that worsens before the period in women on antidepressants? Both women who got additional hormone in the second phase and those who got placebo improved significantly, so we cannot say whether the additional hormone made a difference. Review, 2006 How do doctors tell PMS and PMDD apart from other conditions? This review explains that diagnosing PMS and PMDD requires at least 2 months of tracking symptoms day by day, plus a full medical check to rule out other causes. There is no single quick test for either condition. Survey study, 2006 Does eating soy help with PMS symptoms? Higher dietary intake of soy isoflavones correlated with fewer menstrual symptoms. The link suggests soy might help, but this study cannot prove soy causes the benefit. Randomised trial, 2005 Does intermittent luteal phase medication help PMDD symptoms during the first days of menstruation? Yes. Symptom improvement from luteal phase-only medication continued into the first 2-3 days of menstruation with similar benefit to continuous treatment, and abruptly stopping the medication did not cause withdrawal symptoms. Interview study, 2005 Can doctors correctly diagnose PMDD and depression in gynecology clinics? Gynecologists diagnosed PMDD correctly 80% of the time but depression only 48% of the time. Ironically, they were more confident about their depression diagnoses despite being less accurate. Survey study, 2005 What are the main symptom types of PMDD? The study found that mood symptoms are most important in PMDD, but physical symptoms and feeling overwhelmed are also significant. Since this was a survey of college students in Brazil, the findings may not apply to all women. Cohort study, 2005 How common is PMS and how severe is it in young college women? More than half of college women (53%) met PMS diagnostic criteria, with 31.7% having severe symptoms. About 18% met criteria for PMDD, the most severe form. This is a high prevalence, though the study used convenience sampling in one country. Survey study, 2004 What is PMDD? PMDD is a severe form of PMS with at least 5 of 11 symptoms, including mood changes or irritability, that happen before your period and go away when you bleed. Symptoms must last at least a year and be bad enough to disrupt daily life. Survey study, 2004 How common is PMS in teenage girls, and can diet help it? 61.4% of girls had PMS, mostly mild or moderate. The most common symptoms were stress and nervousness (87.6%). Girls who drank more milk reported less bloating and cramps. Survey study, 2004 Does what you eat affect premenstrual symptoms? Eating more fat was linked with worse premenstrual symptoms, while eating more carbohydrate-rich foods was linked with fewer symptoms. Soy products had no clear link to symptoms. Study, 2004 Which adolescents have the most serious premenstrual symptoms? The study found two different patterns of symptoms. Adolescents with anxiety and anger had more severe symptoms and more school absences, while those with fatigue had less impact on their lives. Cohort study, 2003 How should doctors determine which cycles count as PMDD? Different diagnostic methods give very different results. Using a 30% threshold for symptom presence and 50% for recovery after the period correctly identified 92% of PMDD cycles in women with PMS. Non-randomised trial, 2003 How many women with PMS want to participate in research studies? Very few. Only 10% of women with current PMS symptoms agreed to participate, and only 22% of those who started confirmed their diagnosis by keeping daily symptom charts. Survey study, 2003 Is how much control women feel over their life linked to premenstrual symptoms? Yes. Women who felt they had less control over their circumstances were more likely to have premenstrual symptoms, anxiety, and depression. Women felt especially out of control during the premenstrual phase compared to other times in their cycle. Survey study, 2003 How common is PMS and does it affect academic performance in university students in Ethiopia? 27% of students met diagnostic criteria for PMS or PMDD. About 14% frequently missed classes and 15% missed exams or got lower grades due to PMS symptoms. These academic impacts were significantly associated with symptom severity. Survey study, 2003 What is the difference between PMS and PMDD, and how are they diagnosed? PMS and PMDD are distinguished by how many symptoms are required. PMDD needs at least five symptoms, while PMS needs just one distressing symptom, and diagnosis requires daily diaries since no blood test exists. Survey study, 2003 How common is PMDD in women in Bosnia and Herzegovina and what are the most common symptoms? 52% of women in Bosnia and Herzegovina met diagnostic criteria for PMDD. The most common symptoms were depressed mood (68%) and breast swelling or weight gain (81.8%). Survey study, 2003 Is there a quick questionnaire to screen for severe PMS and PMDD? The PSST is a brief questionnaire that can identify women with severe PMS or PMDD in a clinic visit. It is faster and more practical than keeping a daily symptom diary for two cycles. Lab study, 2002 Does the official list of PMDD symptoms match what women seeking treatment actually experience? The official list of PMDD symptoms matched 19 of 22 most frequently reported symptoms. When other mental health conditions were ruled out, irritability and anger were more common than depressed mood. Survey study, 2001 How does a woman's attitude toward menstruation relate to her premenstrual symptoms? A clear connection was found between how women view menstruation and their premenstrual symptoms. Women who saw menstruation as weakening them physically and emotionally experienced more premenstrual symptoms. Survey study, 2001 Does oral contraceptive use affect daily mood? Yes. Birth control pills can change how mood varies from day to day. The effect depends on what type of pill a woman takes and whether she or her family has a history of psychiatric problems. Case report, 2001 Does taking nefazodone just during the luteal phase help PMDD? Yes. All three women who took nefazodone reported marked improvement in symptoms. All three had complete relief of emotional symptoms, and two also had complete relief of body symptoms. This is a very small study. Survey study, 2001 Do women with PMDD have other mental health conditions or personality traits? Most women with PMDD (77%) had experienced other mood or anxiety disorders in their past, compared with only 17% of women without PMDD. Two-thirds of women with PMDD who had children experienced postpartum depression. Survey study, 2001 Does how much you tend to worry affect your mood before your period? Yes. Women who scored higher on a personality test for worry and upset feelings reported more negative mood before their period, even accounting for baseline mood. Women taking birth control pills had higher worry scores. Survey study, 2000 Can the Premenstrual Assessment Form questionnaire diagnose PMDD? The questionnaire correctly identified most women with PMDD symptoms compared to healthy women, but it cannot confirm a definite PMDD diagnosis alone. Daily symptom tracking is needed. Non-randomised trial, 2000 Does Vitex agnus castus (chasteberry) extract reduce PMS symptoms? Vitex extract reduced PMS symptoms by 42.5% during treatment, with 47% of women experiencing at least 50% improvement. Without a control group, we cannot be certain improvement was from the herb versus placebo or natural improvement. Survey study, 2000 Is there a link between premenstrual syndrome and postnatal depression? This exploratory study found an association between PMS and later postnatal depression, suggesting women with PMS might be at higher risk. However, this is very early research and we cannot be confident the results apply widely. Survey study, 2000 Does the birth control pill with drospirenone improve mood and skin during the cycle? Yes. Women who took drospirenone-containing pills reported feeling worse, having worse skin and hair, and weighing more after they stopped and switched to standard pills. Survey study, 1999 How do menstrual and premenstrual symptoms affect female military cadets? Almost all cadets' menstrual cycles changed during their first year. Many reported symptoms interfered with physical activities. Many also struggled to access, change, and dispose of menstrual products. Survey study, 1999 What are the main symptom clusters in PMS and how do they vary during the menstrual cycle? Four main clusters were identified: turmoil, fluid retention, somatic symptoms, and arousal symptoms. Some clusters remain consistent across the cycle, while others change more. Non-randomised trial, 1999 Does taking sertraline only in the second half of the cycle help PMDD? In this very small study, half of the women who completed treatment (3 out of 6) showed significant improvement in PMDD symptoms with luteal-phase sertraline dosing. Randomised trial, 1999 Which symptom rating scales best measure PMDD? Three simple rating scales reliably measure PMDD symptoms and track treatment effects. They work well together, with strong agreement between them (correlations 0.70 to 0.82). Survey study, 1999 Does the Chinese version of the Menstrual Distress Questionnaire work as well as English? Yes, mostly. Most items translated equivalently between English and Chinese, though some items could be improved further. Survey study, 1998 What is the best way to measure breast pain that comes and goes with your period? A daily visual pain scale works much better than asking women to remember their pain later. Women with cyclical breast pain reported much higher pain levels during menstruation (5.3 out of 10) compared to women without cyclical pain (3.5). Case report, 1998 Does how women manage anger affect how bad their PMS gets? No, not significantly. Women who coped with anger differently had similar PMS severity. But stress from work and family life was linked to worse PMS. Survey study, 1998 Does aggression change during different phases of the menstrual cycle? No. Aggression rates did not change across different phases of the menstrual cycle, though women who reported more PMS symptoms showed higher aggression throughout their cycle compared to women with fewer symptoms. Survey study, 1998 How common and severe are premenstrual symptoms in teenage girls? Premenstrual symptoms are nearly universal. 88% reported moderate or worse symptoms and 56% reported extreme severity. Older teenage girls had significantly more intense symptoms than younger ones. Survey study, 1997 Does how women rate their own premenstrual symptoms match a standard questionnaire? Women's self-rating of symptoms roughly matches a standard questionnaire, but about one-third of women don't recognize they have symptoms even though a formal questionnaire would identify them as having them. Survey study, 1997 Do menstrual cycle moods and symptoms affect school grades? Yes, but only slightly. Menstrual cycle symptoms predicted grades in 14% of cases premenstrually, 7% during menstruation, and 13% between periods, mostly negatively, though with some positive effects in certain subjects. Case-control study, 1997 Do current PMDD diagnostic criteria measure what they are supposed to measure? The study suggests the criteria may be incomplete. It recommends that anger and irritability, depressed mood, and problems with relationships be expanded with more items on symptom checklists. Survey study, 1997 Does learning about PMDD as a diagnosis change how women think about their symptoms? Learning that PMDD is a diagnosis didn't change women's own symptom reports, but it did make them more likely to see premenstrual problems as a psychiatric issue for women in general. Interview study, 1997 What diagnostic system should doctors use for menstrually related disorders? The paper proposes new diagnostic criteria based on when symptoms occur rather than their type, to help doctors from different specialties communicate better about menstrual cycle related problems. Interview study, 1997 Is PMDD different from PMS, and what causes it? PMDD is a more specific diagnosis than PMS. It involves low serotonin and melatonin in the brain, and antidepressant SSRIs reduce symptoms according to rigorous studies. Interview study, 1997 Is PMDD related to other mood disorders like depression? PMDD shares many symptoms with depression and other mood disorders and is classified with them in diagnostic manuals. However, important differences suggest PMDD is distinct, though its exact relationship remains unclear. Case-control study, 1996 Are women with PMS more angry or do they have different feelings of control than women without PMS? No clear difference in anger or feelings of control was found between women with and without PMS. However, 89% of women thought they had PMS when only 22% actually met the official diagnosis criteria. Survey study, 1996 Do women with alcohol dependence drink more during the premenstrual phase? Yes, about one-third of women with alcohol dependence drank more premenstrually than at other times of the month. This finding is based on a small study, so we cannot be very certain about it. Cohort study, 1996 Can hormones trigger PMS symptoms in women without ovaries or a uterus? Not clearly. Some individual women showed links between progesterone and symptoms, but results overall were not statistically significant. Women don't respond uniformly to hormones. Case report, 1996 Do hormone changes around menstruation cause seizures in women with epilepsy? Yes. In 5 women with epilepsy, seizures happened around their period due to hormone changes. Low progesterone and high estrogen triggered seizures in 4 women. In 1 woman, lack of ovulation was the cause. Cohort study, 1996 Do PMS mood swings really rise before a period, or is that just how we remember it? In this small study, physical symptoms like fatigue, pain and breast tenderness were confirmed to rise around the period, but mood swings and irritability were not confirmed when tracked day by day, even though women recalled them as worse premenstrually when asked after the fact. Study, 1996 Is PMDD officially recognized as a mood disorder? Yes. PMDD is classified as a mood disorder in the medical system used for diagnosis. More evidence is supporting this classification. Cohort study, 1995 How well do three different PMS measurement tools agree with each other? All three tools (PMSD, MDQ, and DRF) measure PMS symptoms reliably and their results correlate strongly, with correlations ranging from 0.67 to 0.81. This means the shorter PMSD tool works as well as longer questionnaires. Survey study, 1995 What's different about women who seek treatment for premenstrual mood changes? Women seeking treatment reported significantly more depression, anxiety, and unwanted negative thoughts than those not seeking treatment. Both groups had similar physical symptoms. The commonly used 30% improvement rule did not distinguish the two groups well. Case-control study, 1995 Do women with PMS drink differently during their menstrual cycle? Women with PMS drank significantly less fluid than women without PMS at all cycle phases, though neither group changed their drinking across cycle phases. The reduced intake appeared to be subconscious. Survey study, 1995 Do premenstrual symptoms differ between rural and urban Mexican women? Physical symptoms were similar. Urban women reported more severe psychological and behavioral symptoms than rural women. Survey study, 1994 Does regular exercise reduce negative mood and pain during the menstrual cycle? Yes. Regular exercisers reported significantly lower scores on negative mood, poor concentration, behavior change, and pain compared to non-exercisers, but similar positive mood levels. Case-control study, 1994 Do women with PMS have different mineral levels in their blood? Yes. Women with PMS had significantly lower magnesium levels (0.70 versus 0.87 mmol/l) and a lower zinc-to-copper ratio (1.40 versus 1.51) than women without PMS. Survey study, 1994 How do women describe their own premenstrual changes? Women describe changes in a structured way covering whether changes happen, when they occur, what type they are, and what effects they have. This structure differs slightly from how standard questionnaires ask about PMS. Survey study, 1993 Does guided imagery reduce PMS symptoms and lengthen periods? Guided imagery significantly reduced PMS distress and increased menstrual cycle length in women who completed the full program. However, this is preliminary evidence from a small group, and larger studies with control groups are needed. Survey study, 1993 Does menstrual cycle phase affect how often women get infection symptoms? Women reported more infection symptoms during menstruation and the week before, compared to the middle of their cycle. However, this appears linked more to stress and menstrual distress than to the cycle phase itself. Survey study, 1993 Do women with menstrual migraine also have premenstrual syndrome? Many do. Fourteen of 22 women with menstrual migraine met diagnostic criteria for PMS, and their symptom patterns followed the same menstrual rhythm as women with PMS alone. Survey study, 1992 Do women with digestive problems experience worse stomach symptoms during their period? Yes. Women with functional bowel distress reported significantly worse stomach pain, nausea, and diarrhea during menstruation compared to women without bowel problems. They also had more stomach pain on other days of the cycle. Randomised trial, 1992 Does fluoxetine (Prozac) help severe PMS? Yes. Fluoxetine significantly improved behavioral symptoms by 75%, physical symptoms by 40%, and total symptoms by 62% compared to placebo, with no significant side effects. Study, 1991 Is the Premenstrual Assessment Form a useful tool for measuring premenstrual symptoms? The tool gives consistent results in different cities, but it may diagnose too many people with premenstrual symptoms, suggesting stricter criteria are needed. Cohort study, 1991 Do women who think they have PMS often have other psychiatric conditions too? In this very small study, most women who came in complaining of PMS had a lifetime history of some psychiatric illness, and only a minority actually met strict criteria for PMS. This suggests careful psychiatric evaluation is needed, but the study is far too small to generalize. Survey study, 1991 Is premenstrual depression a sign of psychiatric illness? No. Premenstrual depression marks more severe PMS and is linked to anxiety symptoms, but PMS itself is not evidence of a psychiatric disorder. Survey study, 1991 Is a 10-item symptom checklist as good as a 95-item one for measuring PMS? Yes, a 10-item checklist had high internal consistency and reliability. It measures three main symptom areas: mood, water retention, and pain. Survey study, 1990 Does alcohol use change during the premenstrual phase, and how does it relate to PMS symptoms? 8 of 14 women drank differently during the premenstrual phase. Women who drank more premenstrually had worse symptoms, especially anger and social problems, while those who drank less reported more physical pain. Survey study, 1990 Are brain chemical levels different in women with PMS compared to women without PMS? Yes. Women with PMS had higher blood levels of tryptophan and epinephrine, and different patterns of how brain chemicals changed across the menstrual cycle compared to control women, though these chemical changes didn't always match the actual presence of symptoms. Survey study, 1990 Can psychological tests help identify who has premenstrual complaints? Yes. The study found clear and substantial differences in test scores between women with and without premenstrual complaints. Cohort study, 1990 Is there a reliable way to track and diagnose PMS using a daily symptom diary? Yes. A simple daily symptom calendar was very accurate at telling women with PMS apart from women without it, when used for two cycles in a row. Study, 1990 Do men notice premenstrual changes in women? Yes. 99 college men said they believe women experience premenstrual changes including mood swings, hostility, low self-esteem, physical discomfort, and behavioral changes. Cohort study, 1990 Can premenstrual depression predict whether a woman will develop major depression later? Yes, women whose premenstrual depression scores are higher have a greater risk of developing major depression in the future, and this predictive value holds even after accounting for family history and past depression. Guideline, 1990 Can we reliably diagnose a menstrual cycle-related psychiatric disorder? The paper does not answer this. It identifies major problems with the proposed diagnosis, including risks of overdiagnosis, underdiagnosis, and unclear measurement methods. Survey study, 1990 Do women with PMS have low magnesium levels? Yes. Women with PMS have significantly lower magnesium in certain white blood cells compared to women without PMS (p<0.025). Survey study, 1990 Is anxiety related to premenstrual syndrome? Yes. Women with higher levels of anxiety trait are significantly more likely to have premenstrual syndrome, especially psychological symptoms like mood changes. Survey study, 1989 Do women with different types of PMS differ in age, education, or marital status? No significant differences were found in age, education, marital status, or employment between women in three PMS groups. The only difference was that women with pure PMS had lower neuroticism scores and less psychiatric history. Survey study, 1989 How does sample selection affect reported prevalence of premenstrual disorder? Different subtypes of premenstrual disorder exist, but how common each type is depends heavily on whether women were seeking help for premenstrual problems or recruited from the general population. Survey study, 1989 Are women with premenstrual symptoms more likely to have mental health problems? Yes, clearly. About 85% of women experienced moderate to severe symptoms before their period, and women with these symptoms scored significantly higher on mental health screening than those without. Survey study, 1989 What premenstrual symptoms do adolescent girls experience? Almost all adolescent girls report premenstrual symptoms. Most commonly they experience physical discomfort, water retention, and fatigue, along with mood changes like depression and impulsive behavior. Survey study, 1989 What nutrients help with anxiety and mood changes before your period? Yes, certain nutrients are linked to relief from premenstrual anxiety and mood changes. However, the review doesn't identify which specific nutrients are most beneficial. Survey study, 1989 Do women's memories of premenstrual depression match their daily mood ratings? Only about half of women who reported major premenstrual depression on a questionnaire showed matching depression in daily tracking. Women with confirmed depression had worse energy and physical pain too. Survey study, 1988 How do women with PMS differ from those without PMS on mental health? Women with PMS had higher depression and stress than community women without it. Some women without a PMS diagnosis showed cyclical symptom patterns, suggesting they may develop PMS later. Survey study, 1988 When do different PMS symptoms happen during the menstrual cycle? Physical symptoms peaked every 28 days in most women. About half showed this pattern for depression, behaviour, tension and concentration symptoms. Physical and tension symptoms tended to come 1-2 days before depression peaked. Survey study, 1987 Does alcohol use change across the menstrual cycle? Among 30 women who use marijuana, alcohol drinking frequency did not change with the menstrual cycle phase. Women who reported more premenstrual symptoms tended to drink slightly more, but the timing of the cycle did not predict drinking. Study, 1987 Do women smoke more when they drink alcohol, and does the time of their menstrual cycle affect this? Yes, a study of 24 women found that smoking increased when alcohol was available, especially in heavy smokers. Most women also smoked more just before their period. Survey study, 1987 Do women with PMS have lower levels of a pain-relieving chemical in their blood? Yes. Women with PMS had lower plasma beta-endorphin (a natural pain-reliever) in the week before their period and during menstrual flow. However, this very small study of only 11 women needs confirmation in larger research. Review, 1987 Does a dietary program with supplements help premenstrual tension symptoms? Yes, according to both open trials and double-blind studies. A daily supplement of six tablets significantly reduced symptoms compared to placebo over three to six months. Survey study, 1987 Do oral contraceptive pills reduce premenstrual symptoms? Pills reduce some specific symptoms like anxiety, mood changes, and water retention. However, women on pills reported similar total numbers of symptoms as those not on pills. Case report, 1986 How should doctors identify premenstrual tension syndrome? Doctors should look for the timing pattern: symptoms that appear before the period and disappear when it starts. PMS can exist alone or alongside other mental health conditions. Survey study, 1986 Does marijuana use change across the menstrual cycle? No. In women without severe PMS, marijuana use did not vary across the menstrual cycle, even though physical symptoms like pain and water retention worsened before and during menstruation. Survey study, 1986 How common are hostile feelings and social problems before periods? These symptoms vary greatly by group studied: from 15% to 83% for hostile feelings, and from 14% to 92% for social functioning problems. Survey study, 1985 Does stress affect premenstrual symptoms? Yes. Daily stressors had a stronger effect on premenstrual symptoms than major life events. A generally stressful life context was more influential than stress occurring during a specific cycle phase. Non-randomised trial, 1984 Does elevated prolactin cause premenstrual tension? No. Prolactin levels were normal in women with severe PMS. When a drug that lowers prolactin was given, hormone levels changed but symptoms did not improve. Survey study, 1982 Do women without mental health problems experience mood and anxiety changes during their cycle? Women without current or past mental health issues experienced only minor cycle-related mood changes. Water retention was the only symptom that reached statistical significance. Survey study, 1982 Do women remember their PMS symptoms accurately when asked to recall them? No. Women overestimated symptoms when recalling them weeks later compared to what they had recorded daily. Only menstrual cramps and backache showed agreement between methods. Survey study, 1982 Do stressful life events affect PMS and menstrual symptoms? The study found stressful life events were linked to worse premenstrual mood and menstrual symptoms, but the connection weakened significantly when only physical health stress was considered. The cross-sectional design means we cannot prove stress causes these symptoms. Study, 1982 Can we measure all the different types of premenstrual changes women experience? Yes. A new measurement tool called the Premenstrual Assessment Form can measure the wide variety of mood, behavior, and physical changes women experience before their period and recognizes that PMS is not one single syndrome. Survey study, 1982 Are premenstrual and menstrual symptoms separate problems or part of one larger problem? They appear to be part of one larger problem. Although some symptoms are worse before your period and others during it, the symptoms largely overlap. Survey study, 1981 Are premenstrual changes linked to specific types of mental disorders? Yes. Specific types of premenstrual changes were linked to specific types of mental disorders. Premenstrual changes with depression may represent a mild form of mood disorder. Study, 1980 What kinds of changes do women experience before their period? Women reported a variety of physical, behavioral, and mood changes during the premenstrual period, with responses ranging from no change to extreme change. Survey study, 1980 What are the best tools to measure premenstrual tension syndrome? Researchers developed two new diagnostic rating scales that could help standardize how doctors and researchers diagnose and measure PMS severity. Interview study, 1980 What are the main symptoms of severe premenstrual tension and how do they differ from depression or anxiety? In 42 women with severe PMS, the main symptoms were irritability, mood swings, tension, and restlessness that appear and disappear with the cycle. These don't match patterns of depression or anxiety alone. Interview study, 1980 What causes premenstrual tension syndrome? The authors propose that high prolactin levels, possibly combined with low estrogen or progesterone, may cause premenstrual symptoms. This is a theory, not a tested finding. Study, 1980 Does lithium carbonate help women with severe premenstrual tension? Lithium did not reduce physical symptoms and did not work for most women's behavioral symptoms. Measurement tools showed improvement, but this benefit had no real practical value, and side effects were common. Survey study, 1979 Do moods and enjoyment of activities change during the menstrual cycle? When healthy women kept daily records, there were no clear changes in mood or enjoyment of activities during different cycle phases. But when they looked back on a monthly questionnaire about menstrual distress, they reported the typical cycle-related differences. Survey study, 1979 When during the menstrual cycle do menstrual symptoms peak? Symptoms peak in the days immediately before and after menstruation starts, not declining sharply once bleeding begins. Ratings were highest around menstruation onset. Survey study, 1977 Can daily symptom tracking help measure menstrual symptoms? Yes, daily symptom tracking can identify menstrual symptom patterns. The method worked as well as other ways of measuring menstrual distress. Survey study, 1976 Is the Moos Menstrual Distress Questionnaire a reliable tool for measuring menstrual symptoms? Yes, the questionnaire is reliable and consistent over time. However, it cannot tell the difference between women at different stages of the menstrual cycle, which limits its usefulness. Survey study, 1976 Does premenstrual anxiety and depression affect how well women think? Women reported more anxiety and depression before their period, but this mood change did not affect how well they performed on thinking tests. Survey study, 1975 Are psychological factors linked to menstrual symptoms? Psychological factors were linked to some menstrual symptoms like pain and mood changes, but not to others like water retention. The sample was small and the study is from 1975. Study, 1964 How can we measure premenstrual tension syndrome more accurately? Researchers developed two rating tools based on 42 women with severe premenstrual tension syndrome: a 36-item questionnaire women fill out and a 10-item scale for doctors and researchers to use.
