  • Title: Obsessive-compulsive disorder with and without bipolar disorder.
    Author: Mahasuar R, Janardhan Reddy YC, Math SB.
    Journal: Psychiatry Clin Neurosci; 2011 Aug; 65(5):423-33. PubMed ID: 21851451.
    Abstract:
    AIM: Bipolar disorder (BD) is often comorbid with obsessive-compulsive disorder (OCD). In this study, we compared clinical profile and course of subjects with a primary diagnosis of OCD with and without BD. METHODS: We compared 34 subjects with primary diagnosis of OCD with BD and 57 subjects with a diagnosis of OCD without BD. Structured interview schedules, clinical rating scales, and information from clinical charts were utilized to assess patients. RESULTS: OCD with BD was characterized by: (i) an episodic course; (ii) a higher number of depressive episodes, greater suicidality and a higher rate of hospitalization; (iii) fewer pathological doubts and more miscellaneous compulsions; and (iv) poorer insight into obsessive-compulsive symptoms. CONCLUSIONS: Episodic course appears to be typical of OCD with BD. Bipolarity has a pathoplastic effect on OCD and it is possible that some forms of OCD and BD are pathophysiologically related. Bipolar OCD is associated with a higher rate of depressive episodes, higher suicidality and more frequent hospitalizations, suggesting greater morbidity. Long-term prospective follow-up studies and studies addressing pathophysiology and genetic basis are needed to understand the complexity of such comorbidity.
