Cyclothymic mood swings in the course of affective disorders and schizophrenia

Abstract

The authors assessed cyclothymic mood swings and psychosocial adjustment in 38 unipolar depressed, 27 bipolar, 35 schizophrenic, and 27 other psychiatric patients 4 years after hospital discharge and in 153 normal control subjects. The patients were significantly more cyclothymic at follow-up than the control subjects, but there were no differences in cyclothymia between the diagnostic groups. Cyclothymic patients showed significantly poorer posthospital functioning than noncyclothymic patients. These findings raise questions concerning the scope of the hypothesized cyclothymic-bipolar spectrum. Minor mood swings in a variety of patients with poor posthospital adjustment may reflect persistent vulnerability to psychopathology.
