Bipolar Disorder is Common in Depressed Primary Care Patients

Abstract

The high prevalence of patients meeting full criteria for BD and the low rate of identification of BD in primary care patients are consistent with estimates using self-administered questionnaires, but the interview revealed a substantial additional population that could be considered to have subsyndromal BD. Because subsyndromal forms of BD are associated with significant impairment and comorbidity as well as progression to frank BD, recognition of both full and subthreshold BD in primary care practice should be improved.
