BRIDGE Study Warrants Critique

Arch Gen Psychiatry. 2012;69(6):643-645. doi:10.1001/archgenpsychiatry.2012.118

The Bipolar Disorders: Improving Diagnosis, Guidance and Education (BRIDGE) study1 by Angst et al has received coverage in psychiatric online media.2-4 The message is that almost half the patients with a major depressive episode have undiagnosed bipolar disorder and are “not receiving necessary mood stabilizer treatment.”2 Such views are controversial and far from the mainstream as reflected in International Statistical Classification of Diseases, 10th Revision and DSM-IV. Yet the BRIDGE study findings were published without accompanying commentary or critique.
