Premenstrual Exacerbations of Mood Disorders

Premenstrual exacerbation of mood disorders has received little attention, despite the recent interest in premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS). Differentiating between PMDD/PMS and other disorders, which worsen premenstrually, is a poorly understood diagnostic challenge. Controversy also focuses on a possible coexistence of PMDD and other mood disorders. This review discusses the differences between mood-disorder exacerbations and premenstrual disorders, evidence for premenstrual magnification of mood disorders, and possible mechanisms for these variations as well as clinical implications.
