What is Premenstrual Dysphoric Disorder (PMDD)?

Between 3-8% of menstruating women experience some form of premenstrual dysphoric disorder.  Beyond premenstrual syndrome, PMDD can cause far more extreme emotional symptoms that may interfere with day-to-day life.  These may include feelings of depression, mood lability, irritability, fatigue, difficulty focusing, and anxiety.

The symptoms of PMDD are cyclic and associated with the patient's menstrual cycle.  They are normally present shortly after ovulation and end following menstruation and last for about one week.

However, the most extreme cases can last for up to two weeks.
