Review, 2026

How well do SSRIs treat PMS?

SSRIs like sertraline and fluoxetine are first-line treatments for severe PMS. They work at low doses, are safe with few side effects, and reduce symptoms by affecting serotonin and brain chemistry related to mood.

Cohort study, 2026

Does having PMS before pregnancy increase the risk of postpartum depression?

Yes. Women with a PMS history were 45 percent more likely to develop postpartum depression within one year after birth, with 5.4 percent of women with PMS developing it compared to 3.8 percent without PMS.

Systematic review, 2026

Why do some women experience mood changes linked to their menstrual cycle?

Evidence shows these women have normal hormone levels but heightened sensitivity in their brains and cells to hormone changes. This explains PMDD and some postpartum and perimenopausal mood problems, and has led to new treatments.

Cohort study, 2026

Do premenstrual disorder and postpartum depression share the same genetic causes?

Yes. The conditions share significant genetic overlap with genetic correlation of 0.47 to 0.66. Two genetic locations were identified that affect both disorders, both involving brain response to hormones.

Randomised trial, 2026

Does mindfulness training reduce PMS symptoms and fear about childbirth?

Yes. Women who completed mindfulness training had significantly fewer PMS symptoms, less fear about childbirth, and better psychological wellbeing than the control group.

Cohort study, 2025

Is there a link between premenstrual disorders and autoimmune disease?

Yes. Women with autoimmune disease have 12% higher risk of premenstrual disorders, and women with premenstrual disorders have 23% higher risk of autoimmune disease.

Cohort study, 2025

Do women with a history of PMS or PMDD have more depression during pregnancy and after birth?

Women with PMS or PMDD history had higher depression scores throughout pregnancy and postpartum, with PMDD carrying higher risk than PMS.

Case-control study, 2024

Do steroid hormone levels change differently across the menstrual cycle in women with PMDD?

Yes. Progesterone rises earlier in the cycle in women with PMDD, leading to higher levels around ovulation and a sharper drop in the late luteal phase. This different pattern may trigger symptoms.

Case-control study, 2024

Are premenstrual disorders and postpartum depression connected?

Yes, they are connected both ways. Women with premenstrual disorders are 4.76 times more likely to develop postpartum depression. Women with postpartum depression are 1.81 times more likely to develop premenstrual disorders later.

Systematic review, 2023

What hormonal treatments have been tested for PMDD, menstrual migraine, and catamenial epilepsy?

Hormonal treatments have been tested 56 times for premenstrual mood disorder, 21 times for menstrual migraine, and 8 times for catamenial epilepsy. Combined oral contraceptives were a frequent focus.

Review, 2023

What treatments help mental and physical health problems linked to the menstrual cycle?

Multiple treatment approaches work including medicines, psychotherapy, and hormonal therapy. An interdisciplinary team approach combining different specialties works best.

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

Does saffron help with PMS, labor pain, and menopause symptoms?

Yes, saffron improves mood and reduces psychological symptoms of PMS and menopause, and helps reduce labor pain and recovery time, though limited studies exist.

Survey study, 2022

What causes PMS and PMDD and what new treatments are being studied?

PMS and PMDD involve changes in hormone sensitivity, serotonin levels, genetic factors, and inflammation. New treatments under research target progesterone receptors and inflammatory pathways.

Systematic review, 2022

What increases the risk of depression after childbirth?

Premenstrual syndrome is the strongest known risk factor for postpartum depression, nearly doubling the risk. Violent experiences and unintended pregnancy are also strong risk factors.

Cohort study, 2021

Does having PMS before pregnancy increase the risk of postpartum depression?

Yes. Women with frequent PMS before pregnancy had higher risk of postpartum depression after birth, with the risk rising as PMS became more frequent.

Guideline, 2021

How should migraine be managed in women, particularly menstrual migraine?

This guideline covers migraine treatment approaches, noting that menstrual migraine, pregnancy, contraception, and hormone therapy are specific considerations. The abstract does not provide specific treatment details for menstrual migraine.

Systematic review, 2021

Are there hormone changes that could explain PMDD or depression in women?

Yes, women with PMDD have lower estrogen levels during the luteal phase of their cycle, and women with depression have lower testosterone levels. These hormonal differences may contribute to their symptoms.

Systematic review, 2019

Is there a link between premenstrual syndrome and depression after childbirth?

Most studies found a link between PMS and postpartum depression, though some found this link disappeared when other factors like personality were considered. The connection appears real but may depend on circumstances.

Review, 2015

Do hormonal contraceptives have benefits beyond preventing pregnancy?

Yes. Combined oral contraceptives can reduce heavy periods, anemia, and PMDD symptoms. Several other contraceptive methods also offer additional health benefits.

Randomised trial, 2011

Does phone support reduce stress during IVF waiting?

No, the stress scale showed no difference, but women perceived the support as helpful and wanted more.

Randomised trial, 2006

Do herbal remedies help with PMS, pregnancy nausea, or hot flushes?

Preliminary evidence suggests chaste tree helps PMS, ginger helps pregnancy nausea, and black cohosh helps hot flushes, but the evidence is not strong enough to be certain.

Randomised trial, 2003

What complementary and alternative medicines help with women's reproductive health issues?

Acupressure helps with pregnancy nausea and calcium helps with PMS. Vitamin B6, ginger, magnesium, chaste-tree berry, low-fat diet, exercise, and fish oil show promise but need more research.

Review, 2003

How do menstrual cycle hormones affect the brain and cause mood disorders like PMDD?

A hormone called allopregnanolone acts on brain receptors. Changes in this hormone during the cycle may cause mood and behavioral symptoms in up to 20% of people through three mechanisms: direct effects, building tolerance, and withdrawal effects.

Review, 1992

Is PMS really caused by hormones?

The evidence that PMS is caused by hormones is unclear. Psychological and individualized treatments may work better than hormone treatments for PMS.

Review, 1989

Are mental health conditions linked to the reproductive cycle?

Psychiatric disorders like PMS and postpartum depression are linked to the menstrual cycle and pregnancy. But research on PMS is still early and many questions remain.

Cohort study, 2026

Is wanting to get pregnant linked to worse PMDD symptoms?

No. Among full-time working women, wanting to get pregnant was not linked to having PMDD, though it was weakly linked to slightly higher symptom scores.

Case-control study, 2026

Does PMS increase the risk of depression after childbirth in women with a history of depression?

Yes. Women with PMS had a 45.5% rate of postpartum depression compared to 22.5% without PMS, making it 2.87 times more likely.

Survey study, 2026

Do people with ADHD traits have higher rates of PMDD than others?

Yes, people with ADHD traits had significantly higher risk of PMDD. People with autism traits did not show a higher risk of PMDD.

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.

Cohort study, 2026

How do premenstrual symptoms change after pregnancy, and what predicts worse symptoms?

Premenstrual symptoms increase modestly after childbirth. Postpartum depression and severe period pain are linked to higher symptom scores.

Randomised trial, 2026

Does vitamin D help with PMS symptoms?

This review found that low vitamin D is linked to more severe PMS symptoms, and supplementation significantly reduces PMS scores, especially for mood-related symptoms. However, the studies used different doses and measuring methods, so more rigorous research with standardized dosing is needed.

Survey study, 2026

Does fear of childbirth explain why women with PMS are more likely to develop postpartum depression?

Yes, partially. Fear of childbirth accounts for 31.03% of the effect of PMS on postpartum depression in first-time mothers, and 43.62% in experienced mothers. This suggests PMS creates ongoing emotional vulnerability through pregnancy and after birth.

Cohort study, 2026

How do menstrual cycle hormones affect suicide risk in women?

A review suggests hormone changes during the menstrual cycle, especially in the luteal phase, may affect brain chemistry and increase suicide risk in vulnerable women. The exact mechanisms are not fully understood.

Survey study, 2026

Does a history of mood problems with your period predict depression during menopause?

Yes, women with a history of mood changes before their period or depression after childbirth were more likely to have depression symptoms during menopause.

Review, 2026

Do PMDD, postpartum depression and perimenopausal depression have the same genetic causes?

It's unclear. Researchers have looked at several of the same genes in all three conditions but found inconsistent results. Most genetic research has focused on postpartum depression, not PMDD.

Survey study, 2025

Do women with bipolar disorder who had PMS or postpartum depression have worse mood problems during menopause?

Yes. Women with bipolar disorder who had premenstrual symptoms are 6.189 times more likely to have mood episodes during menopause, and those with postpartum depression are 2.635 times more likely to have depression during menopause.

Review, 2025

Does creatine supplementation help women's health?

Creatine supplementation may improve muscle strength, exercise performance, mood, and cognitive function in women. However, most research so far is small and more studies are needed, especially in women approaching menopause.

Study, 2025

Can blood markers that predict depression after childbirth also predict PMDD?

A blood marker linked to depression after childbirth also showed promise in identifying women with PMDD, particularly during the luteal phase of the menstrual cycle.

Cohort study, 2025

Do women with epilepsy show different brain patterns during different phases of their menstrual cycle?

Yes. Women with epilepsy showed abnormal changes in brain activity during the perimenstrual phase compared to women without epilepsy, suggesting increased brain excitation during this time.

Review, 2025

What do menstrually-related mood disorders and postpartum depression have in common?

They share similar symptoms like anxiety, irritability, and depressed mood. They may be caused by similar hormone changes and stress effects on the brain, but more research is needed to understand all the factors involved.

Review, 2025

How does progesterone affect mood and brain function?

Progesterone influences how your brain processes emotions and manages stress. In women with PMDD, targeting progesterone receptors can improve mood symptoms before your period.

Survey study, 2024

How much do Indonesian 9th graders know about PMS and what are their attitudes?

Most girls (56.25%) had a positive attitude toward PMS, but only 15.6% showed good knowledge about managing it.

Survey study, 2024

Does having PMS or PMDD before pregnancy increase the risk of depression during and after pregnancy?

Yes. Women with PMS or PMDD before pregnancy had a higher risk of depression during pregnancy and in the first month after birth.

Survey study, 2024

Does having PMS or PMDD before pregnancy increase the risk of depression during and after pregnancy?

Yes. Women with PMS or PMDD before pregnancy had a higher risk of depression during pregnancy and in the first month after birth.

Randomised trial, 2024

Does sertraline change brain chemicals in people with PMDD, and does this relate to symptom improvement?

Sertraline changed specific brain chemical levels (pregnanolone) in people with PMDD compared to baseline. However, whether these chemical changes directly caused symptom improvement was not tested.

Cohort study, 2024

Is PMS before pregnancy linked to postpartum depression?

Yes. Women with PMS symptoms before pregnancy were more likely to develop postpartum depression at day 7 to 10 after birth, 6 weeks postpartum, and 6 months postpartum. This association was especially strong in women who had been pregnant multiple times.

Survey study, 2023

Is a history of PMS linked to postpartum depression?

Yes. Women with more severe PMS were more likely to experience baby blues (low mood after birth) and postpartum depression. The correlation between baby blues and PMS was 0.397.

Cohort study, 2023

Does COVID-19 vaccination change the menstrual cycle?

About 25% of vaccinated people reported temporary menstrual changes, most after the second dose. The vaccines are safe and effective, but the study could not determine whether changes were caused by the vaccine or are normal cycle variation.

Randomised trial, 2023

Does estrogen and progesterone around the period help with suicidal thoughts?

In 26 women with suicidal thoughts, giving estrogen and progesterone before the period changed some brain chemicals that may relate to suicide risk. This is very early research with a small sample, so we cannot be sure yet.

Randomised trial, 2023

Do very low doses of fluoxetine help emotional PMS symptoms?

Yes. Low doses of fluoxetine (5 to 10 mg daily) reduced emotional PMS symptoms when taken only before menstruation, with 10 mg being more effective.

Survey study, 2022

What are the biggest research gaps in women's health, especially for menstrual conditions?

Research is lacking in many important areas, especially communication between women and doctors about health, and support for menstrual conditions like PMDD and heavy periods. There is more research on menopause but not on how to help women manage other conditions.

Systematic review, 2022

Does having PMDD increase the risk of depression during pregnancy or after birth?

Yes. Women with PMDD have higher risk of depression after giving birth. Evidence for depression during pregnancy is less clear from current studies.

Cohort study, 2022

Does depression after pregnancy affect when periods return and how severe menstrual symptoms are?

Women with higher depression scores at 6 months postpartum were more likely to have their periods return within 6 months. Women whose menstrual symptoms worsened had higher depression scores, but this wasn't confirmed when adjusted for other factors.

Survey study, 2022

Does emotional processing change through the cycle if someone had postpartum depression?

Yes. Women with a history of postpartum depression showed depression-like thinking patterns during the late luteal phase, like dwelling on negative self-views and remembering sad information better. Healthy women did not show this pattern.

Case-control study, 2022

Are differences in emotional brain activity in women with PMDD related to progesterone-derived neurosteroids?

Women with PMDD show greater emotional brain activity during the late luteal phase, and this activity is related to a different balance of two neurosteroids (ALLO and ISO) compared to women without PMDD.

Randomised trial, 2022

Does having an irregular menstrual cycle before pregnancy increase depression during pregnancy?

Yes, women with irregular cycles before pregnancy were more likely to have depression during pregnancy. Cycle length itself did not predict depression, only how consistent the cycles were.

Study, 2022

Are premenstrual symptoms related to postpartum depression in women after birth?

Two specific premenstrual symptoms - headache and feeling overwhelmed - were more strongly linked to postpartum depression than PMDD overall. History of depression, being in a relationship, history of miscarriage, and age were also related to postpartum depression.

Randomised trial, 2021

Does sepranolone reduce PMDD symptoms?

Sepranolone showed benefit for PMDD distress compared to placebo, but the main overall symptom score was not significantly different from placebo in the primary analysis. A follow-up analysis using a longer symptom window showed sepranolone 10 mg was significantly better.

Randomised trial, 2021

Does blocking progesterone receptors help women with PMDD control anger and aggression?

Yes, according to this study. Women taking the medication had a 93% response rate compared with 53.3% on placebo, and their brains showed stronger activity in emotion control regions.
