Premenstrual dysphoric disorder (PMDD) is a condition in which a woman has severe depression symptoms, irritability, and tension before menstruation. The symptoms of PMDD are more severe than those seen with premenstrual syndrome (PMS).
PMS refers to a wide range of physical or emotional symptoms that typically occur about 5 to 11 days before a woman starts her monthly menstrual cycle. The symptoms usually stop when, or shortly after, her period begins.
