Obsessive-Compulsive Disorder

Overview

Description

Obsessive-Compulsive Disorder (OCD) is characterized by the presence of obsessions, compulsions, or both. Obsessions are recurrent and persistent thoughts, urges, or images that are intrusive and unwanted, causing marked anxiety or distress. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules. These behaviors aim to reduce distress or prevent a feared event, but are excessive or not realistically connected to the event. The obsessions or compulsions cause significant distress, are time-consuming, or interfere with daily functioning.

Prevalence

12-month prevalence about 1.2% in the U.S.; similar rates in males and females, though males have earlier onset.

Age of Onset

Bimodal onset — one peak in childhood/adolescence and another in early adulthood.
