Severe PMS May Last Longer Than Thought


(HealthDay News) — For years, women with the severe form of premenstrual syndrome known as premenstrual dysphoric disorder (PMDD) were told that their symptoms should subside the day menstruation begins.

Now, new research suggests that these symptoms, which can include serious mood swings, start about four days before menstruation and can linger through the first three days of menses — as many women with the disorder can attest.

This expanded PMDD definition will help researchers update the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), due out in May 2013. The DSM classifies mental disorders by precise definitions and diagnostic criteria, and it influences treatment decisions and insurance reimbursement.
