Prevalence of bipolar II disorder in outpatient depression: a 203-case study in private practice.

Of 203 consecutive major depressed outpatients in a private setting, 45% had bipolar II disorder, 51% had unipolar depression, and 4% had bipolar I disorder. The observed prevalence of bipolar II disorder was higher then previously reported in clinical samples (10-40%). Bipolar II disorder had age at baseline and onset lower than unipolar depression, and more atypical features. Other variables (baseline depression severity, number of depressive episodes, psychosis, chronicity, comorbidity) were similar, suggesting that the depressive phase of bipolar II disorder differs only in one, but important, dimension (atypical features) from unipolar depression in a private setting.

Antidepressant-associated hypomania in outpatient depression: a 203-case study in private practice.

The incidence of hypomania/mania was studied in 203 consecutive mood disorder outpatients, presenting for treatment of depression in private practice, during a follow-up of 3 to 6 months. Of these 50.7% were unipolar, 45.3% were bipolar II, and 3.9% were bipolar I patients. Compared to unipolar patients, bipolar II patients had a threefold greater risk of switching (17.3% vs. 5.8%, a significant difference), but a lower rate than expected from previous work. In a previous analysis of the whole sample, bipolar II patients had a lower age at onset and more frequent atypical features than unipolar patients. Both unipolar and bipolar switchers had instead early age at onset and frequent atypical features, suggesting that these factors might increase the risk of switching in unipolar depression.
