Anxiety disorders have been historically described as a feature of Bipolar Disorder (BD), and Obsessive-compulsive-bipolar disorder (OCBD) comorbidity has been referred in literature. A survey reports that 55,8% of obsessive-compulsive patients may develop BD in their lifetime. Another survey estimates it at 21%. Mania in Obsessive-Compulsive Disorder (OCD) can occur either as an independent comorbidity or as a result of an antidepressant-induced switch in a patient in anti-OCD drugs.

The aim of this poster is to describe and discuss some aspects of this psychiatric comorbidity, with emphasis on its diagnosis and management, based on a case report.

This case report describes a 38-years-old married male with 5 years history of OCD treated with an antidepressant, admitted at our psychiatric ward due to a manic episode. Its management and therapeutic approach are described.

A baseline of “neurosis” (versus “psychosis”) in some BD presentations has emerged from recent scientific evidence, which prompts its better understanding. As a complex comorbidity, OCBD represents a diagnostic and therapeutic challenge implying further systematic exploration.
