Awareness of illness and subjective experience of cognitive complaints in patients with bipolar I and bipolar II disorder.

Abstract

The authors' goal was to investigate the awareness of illness and subjective cognitive complaints of patients with either bipolar I disorder or bipolar II disorder during a phase of clinical stabilization. They used a structured clinical interview, the Frankfurt Complaints Questionnaire, to determine subjective cognitive complaints, and the Scale of Unawareness of Mental Disorder to assess 57 consecutively enrolled patients with bipolar I or bipolar II disorder. Patients with bipolar II disorder had significantly less insight and a higher level of subjective complaints of stimulus overload than patients with bipolar I disorder. These results suggest that a severe deficit in self-awareness may constitute a distinguishing psychopathological characteristic of patients with bipolar II disorder. Further studies are required to determine if there are associated neuropsychological dysfunctions.
