Obsessive-compulsive neurosis; OCD
Definition of Obsessive-compulsive disorder
Obsessive-compulsive disorder is an anxiety disorder in which people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them feel driven to do something (compulsions).
Causes, incidence, and risk factors
Obsessive-compulsive disorder (OCD) is more common than was once thought. Most people who develop it show symptoms by age 30.
Signs and tests
Your own description of the behavior can help diagnose the disorder. A physical exam can rule out physical causes, and a psychiatric evaluation can rule out other mental disorders.
OCD is treated using medications and therapy.
OCD is a long-term (chronic) illness with periods of severe symptoms followed by times of improvement. However, a completely symptom-free period is unusual. Most people improve with treatment.
