Previous studies have suggested that OCD has comorbidity with bipolar disorder (BD) (1,2). We evaluated the three bipolar OCD cases.
 

C1: Because of the OCD symptoms Chlomipramine was started. Her OCD symptoms improved in several days but manic symptoms was apeeared, switched to Lithium Carbonate. In her out patient exams, manic and obsessive compulsive symptoms were almost never observed simultaneously at the course.
 

C2: In 2003, her complaints started as combined OCD and Manic symptoms, Risperidon and Lithium carbonate were started, manic and OCD symptoms improved. In 2005, OCD and Depressive symptoms appeared together. She got improved with Lithium Carbonate and Chlomipramine. She had one episode with obsessive and manic symptoms or obsessive and depressive symptoms every year till now. Her uncle had Depression and her aunt had Bipolar disorder.
 

C3: Because of his OCD symptoms we prescribed SSRI and lower dose antipsychotic. At that time he hospitalized for his manic symptoms, his OCD was partially remitted. His manic symptoms improved with Lithium carbonate1200p/d. He had resistant obsessive compulsive symptoms and episodic manic symptoms. His father had M. Depressive episodes.
 

Conclusion: Our cases suggest that bipolar OCD has episodic course, treatment resistant symtomatology, high family loading and high frequency of recurrence.
