title: Premenstrual syndrome.
abstract: Premenstrual syndrome is a chronic cyclic disorder with a broad range of morbidity. The syndrome encompasses emotional, behavioral and physical symptoms, usually beginning in the week before menses and ending at the onset of menses or shortly thereafter. To date, the etiology and the most effective treatment are unknown; however, vitamin B6, progesterone and bromocriptine therapies have been advocated.
