Obsessive-compulsive disorder (OCD) is an anxiety disorder in which people have recurring, unwanted thoughts, ideas or sensations (obsessions) that make them feel driven to do something repetitively (compulsions).

The repetitive behaviors, such as hand washing, checking on things, or cleaning, can significantly interfere with a person’s daily activities and social interactions.

OCD often begins in childhood, adolescence or early adulthood. Afflicting some 2.2 million Americans, OCD is equally common in men and women and across social classes and ethnicities.
