A. Bipolar II Disorder. Patients with bipolar type II disorder exhibit hypomania and episodes of major depression.

B. Depressive episodes must be treated cautiously because of the risk of precipitating manic symptoms with antidepressants (occurs in 50% of patients). Antidepressants can also increase the rate of cycling. Patients are often treated concurrently with anti-manics and antidepressants.
C. Patients often require supportive therapy to improve awareness of their illness and to deal with the functional consequences of their behavior.
