Evidence indicates that obsessive-compulsive disorder (OCD) co-occurs with bipolar disorder (BD) at a higher rate than in the general population. Although there is a preliminary indication of a predominant aggregation of OCD in BD patients with bipolar depression (BP-D), no explicit evaluation has previously been undertaken. Using the Structured Clinical Interview for DSM-5 Axis-I disorders and appropriate rating scales, seventy-three BD patients experiencing their first depressive episode were screened for OCD and subthreshold OCD. Nineteen (26%) of the 73 participants in addition to BP-D also met DSM-5 criteria for OCD and 17 (23.2%) patients met criteria for sub-threshold OCD. No differences in demographic and clinical variables evaluated in the study were found between the BP-D patients with and without OCD. Limitations of the study included a relatively small sample size, cross-sectional design and inclusion of only hospitalized BP-D patients. Additional studies are warranted to better define the longitudinal course of comorbid BP-D/OCD, treatment approaches and outcomes of this challenging patient population. Explicit prospective comparison of the rate of DSM-5 OCD and subthreshold OCD in depressive versus manic episodes of bipolar disorder within the same patient is justified.
