define premenstrual dysphoric
Answers from Jacqueline M. Thielen, M.D. Premenstrual dysphoric disorder (PMDD) is a severe, sometimes disabling extension of premenstrual syndrome (PMS). Although regular PMS and PMDD both have physical and emotional symptoms, PMDD causes extreme mood shifts that can disrupt your work and damage your relationships. In both PMDD and PMS, symptoms usually begin seven to 10 days before your period starts and continue for the first few days that you have your period.
Up to 80% women report having some symptoms prior to menstruation. These symptoms qualify as PMS in 20 to 30% of pre-menopausal women. Premenstrual dysphoric disorder (PMDD) is a more severe form of PMS that has greater psychological symptoms. PMDD affects three to eight percent of pre-menopausal women. Antidepressant medication of the selective serotonin reuptake inhibitors class may be used in addition to usual measures for in PMDD.
