Clinical characteristics of mania, mixed mania, and bipolar depression with psychotic features

This study investigated a series of clinical characteristics, including the level of insight into illness and axis I comorbidity, in 125 patients with bipolar disorder with psychotic features categorized in three groups: 62 patients with mania, 28 patients with mixed mania, and 35 patients with depression. All patients were hospitalized and were assessed in the week preceding discharge. The three groups did not differ in the severity of psychopathology as assessed by the Brief Psychiatric Rating Scale (BPRS). The mania group had a lower level of insight into the social consequences of illness than the other two groups, and compared with the group with depression, they had a lower level of insight of poor attention and of poor social judgment. As to axis I comorbidity, obsessive-compulsive disorder was found to be significantly more frequent in depression than in mania. Patients with depression more frequently reported a history of suicidality than those with mania, whereas they did not significantly differ from patients with mixed mania. Our results suggest that mixed mania as assessed at the time of the patient's discharge differs from mania and from depression with respect to a limited number of features among those examined. However, the overall level of insight into illness significantly discriminated mixed mania from mania, but not from depression.
