This protocol is designed to accompany Clinical Protocol # 81-M-0126, The Phenomenology and Biophysiology of Menstrually-Related Mood and Behavioral Disorders. Its original purposes were as follows: 1) to evaluate the efficacy of the gonadotropin releasing hormone (GnRH) agonist depot leuprolide acetate (Lupron) in the treatment of menstrually-related mood disorders (MRMD) by determining whether mood and behavioral symptoms are eliminated when the cyclic secretion of both gonadotropic hormones and gonadal steroids is suppressed, and 2) to determine the possible relevance of gonadal steroids to affective state by sequentially replacing estradiol and progesterone during continued GnRH suppression in those patients whose premenstrual symptoms remit following administration of the GnRH agonist. We observed that GnRH agonist induced ovarian suppression was an effective treatment compared to placebo in women with MRMD. Additionally, women with MRMD but not asymptomatic controls (participating in companion protocol 92-M-0174) experienced a recurrence of mood and behavioral symptoms when either estradiol or progesterone (but not placebo) was added back. These data suggest that women with MRMD have a differential sensitivity to the mood destabilizing effects of gonadal steroids.
