Obsessive compulsive symptoms in bipolar disorder patients: a comorbid disorder or a subtype of bipolar disorder?

Abstract

SummaryOver the last decade increasing attention has been focused on individuals that simultaneously meet the criteria of two or more mental disorders. One of these comorbid conditions, comorbid bipolar disorder and obsessive compulsive disorder, is relatively common among patients with a primary diagnosis of bipolar disorder. But there is little research about the diagnosis and treatment of this comorbid condition, particularly in China. The available studies are primarily cross-sectional studies with small samples, so they are of limited use in understanding the etiology and course of this combined condition. A review of the limited literature suggests that this is a relatively severe, refractory subtype of bipolar disorder that only occasionally merits being considered a comorbid disorder. Larger prospective studies are needed to clarify the etiology, prognosis, and appropriate treatment for this comorbid condition.
