Assessing brain morphological correlates of premenstrual symptoms in young healthy females by Sara B. Marjanovic, Madelene Christin Holm Bukhari, Rikka Kjelkenes, Irene Voldsbekk, Claudia Barth, Lars T. Westlye

“…Premenstrual symptoms have been partly attributed to the brain's sensitivity to menstrual cycle-related hormonal fluctuations, which may be modulated by individual differences in the structural characteristics of the brain. In a population-based sample of 292 non-pregnant females aged 23–43 years, we tested for associations between self-reported premenstrual symptom load and T1-weighted MRI based brain measures of cortical thickness, volume, and surface area as well as subcortical volumes, not controlling for menstrual cycle phase. …”
