Rockefeller University -- Scientists have identified a gene they say is a strong candidate for involvement in premenstrual dysphoric disorder (PMDD) and other maladies associated with the natural flux in hormones during the menstrual cycle. In a paper to be published today in the Proceedings of the National Academy of Sciences, Rockefeller University researchers detail experiments in mice showing that a common human variant of the gene increases anxiety, dampens curiosity and tweaks the effects of estrogen on the brain, impairing memory. If applied in the clinic, the work could help diagnose and treat cognitive and mood disorders related to the menstrual cycle and inform treatments during menopause, such as hormone replacement therapy, researchers say.
