Study, 2014 # What does brain activity show us about PMDD? Women with PMDD show more activity in brain areas that control emotions. This might help explain mood symptoms, but scientists are still working out what this activity means. Moderate study design Women with premenstrual dysphoria (from multiple brain imaging studies) ## What they did This is a review of brain imaging studies. Researchers compared brain activity patterns in women with and without premenstrual mood symptoms. ## What they found Women with premenstrual dysphoria had greater activity in the prefrontal cortex and cerebellum compared to other women. These brain areas handle emotional processing and mood control, suggesting they work together differently in women with PMDD. ## What it means for you Different brain activity might partly explain mood changes in PMDD, but we do not know if this activity causes the symptoms or is just part of having the condition. The findings are from multiple studies, so more research could help clarify the connection. ## About the study Original title The Cerebellum and Premenstrual Dysphoric Disorder Authors Rapkin AJ, Berman SM, London ED Journal AIMS neuroscience Year 2014 Study design Study What was tested Brain imaging studies Open access Yes Read the paper [doi.org/10.3934/neuroscience.2014.2.120](https://doi.org/10.3934/neuroscience.2014.2.120) Original abstract The cerebellum constitutes ten percent of brain volume and contains the majority of brain neurons. Although it was historically viewed primarily as processing motoric computations, current evidence supports a more comprehensive role, where cerebro-cerebellar feedback loops also modulate various forms of cognitive and affective processing. Here we present evidence for a role of the cerebellum in premenstrual dysphoric disorder (PMDD), which is characterized by severe negative mood symptoms during the luteal phase of the menstrual cycle. Although a link between menstruation and cyclical dysphoria has long been recognized, neuroscientific investigations of this common disorder have only recently been explored. This article reviews functional and structural brain imaging studies of PMDD and the similar but less well defined condition of premenstrual syndrome (PMS). The most consistent findings are that women with premenstrual dysphoria exhibit greater relative activity than other women in the dorsolateral prefrontal cortex and posterior lobules VI and VII of the neocerebellum. Since both brain areas have been implicated in emotional processing and mood disorders, working memory and executive functions, this greater activity probably represents coactivation within a cerebro-cerebellar feedback loop regulating emotional and cognitive processing. Some of the evidence suggests that increased activity within this circuit may preserve cerebellar structure during aging, and possible mechanisms and implications of this finding are discussed.
