Sixty-one winter depressive patients were evaluated for evidence of bipolar illness. Using the Schedule for Affective Disorders and Schizophrenia-Lifetime Version and the General Behavior Inventory, only nine (15%) could be considered bipolar. On prospective evaluation of patients during the summer following winter depression, few showed signs of manic or hypomanic symptoms. Also, few patients had a family history of bipolar illness. When patients were asked to evaluate symptoms of winter depression, lack of energy was found to be the most prominent feature of the syndrome.
