“Obsessive-Compulsive Disorder”

Oxford Psychiatry Library

Obsessive-compulsive disorder (OCD) is an anxiety disorder characterized by obsessions and compulsions, and varying degrees of anxiety and depression. Studies have shown OCD to be one of the more common psychiatric disorders, with a lifetime prevalence estimated at 2%-3%, approximately twice that of schizophrenia. OCD is also considered to be one of the most disabling of psychiatric disorders and it presents a tremendous economic and social burden, both for the affected individual, and family, and for society at large. In contrast to other psychiatric conditions of a comparable or lesser prevalence and patient burden, relatively little is understood about the aetiology, and cognitive effect of OCD.
