Bipolar Disorder and PMS
Premenstrual worsening of mood is common among women with depression, but little is known about how often women with bipolar disorder experience worsening of their mood premenstrually. In a study by Payne et al. (2007), premenstrual symptoms were reported by twice as many women diagnosed with mood disorders (mixture of Bipolar Disorder and Major Depressive Disorder) than by women who did not have a psychiatric diagnosis (67.7% vs. 33.7%). These results suggest that PMS symptoms are particularly common in women with bipolar disorder and major depressive disorder. However, this study involved women reporting prior experiences with PMS, which is not always as accurate as studies that involve prospective monitoring to obtain real-time reporting of PMS symptoms. Such prospective studies of PMS in women with bipolar disorder are sparse and have inconsistent conclusions.
