Systematic review, 2026 # Are there differences in brain activity in women with PMDD? Yes, women with PMDD show differences in brain activity compared to women without PMDD, particularly in areas involved in emotion regulation and stress processing. Strong study design 294 women with PMDD and 304 healthy control women ## What they did They reviewed fMRI brain imaging studies comparing brain activity in 294 women with PMDD to 304 healthy control women. ## What they found Women with PMDD showed decreased activity in brain regions involved in emotion regulation (anterior cingulate cortex, dorsolateral prefrontal cortex, medial orbitofrontal cortex, postcentral gyrus) and increased activity in emotion-processing regions (amygdala, insula). They also had weaker connections between regulatory and emotional brain regions. ## What it means for you PMDD involves widespread differences in how the brain regulates emotions and processes stress, not just one area. These differences might explain why about 40 percent of women with PMDD do not respond to standard medication. Limitation: brain imaging results vary between studies. 598 total participants 294 women with PMDD 40% don't respond to SSRIs ## About the study Original title Functional MRI evidence of brain alterations in premenstrual dysphoric disorder: a systematic review Authors Bartoszewicz K, Szurowska E Journal Frontiers in psychiatry Year 2026 Study design Systematic review What was tested None - observational brain imaging study Open access Yes Read the paper [doi.org/10.3389/fpsyt.2026.1795420](https://doi.org/10.3389/fpsyt.2026.1795420) Original abstract Introduction: Premenstrual Dysphoric Disorder (PMDD) affects approximately 1.6% of women of reproductive age and significantly impacts quality of life. Despite its prevalence, the underlying pathophysiology remains incompletely understood. First-line treatment typically involves selective serotonin reuptake inhibitors (SSRIs); however, approximately 40 percent of women with PMDD do not respond to these medications. This systematic review synthesizes current evidence on functional brain alterations in women with PMDD, as assessed using functional magnetic resonance imaging (fMRI), with the goal of identifying potential novel therapeutic strategies. Methods: Data from 598 participants, including 294 PMDD patients and 304 healthy controls, were analyzed. Results: The findings suggest alterations in both topdown regulatory mechanisms and large-scale brain networks, including the salience network, default mode network, and executive control network. These alterations are characterized by decreased activation in the anterior cingulate cortex, dorsolateral prefrontal cortex, medial orbitofrontal cortex, and postcentral gyrus, alongside increased activation in the amygdala and insula, as well as impairments in corticolimbic connectivity. Discussion: These results highlight the complexity of PMDD, implicating widespread neural circuits rather than a single localized dysfunction. Targeting these mechanisms may inform the development of novel interventions for symptom relief. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/, identifier CRD420251174749.
