Obsessive-compulsive disorder - Symptom

Alternative Names

Obsessive-compulsive neurosis; OCD

Symptoms:

Obsessions or compulsions that are not due to medical illness or drug use
Obsessions or compulsions that cause major distress or interfere with everyday life

There are many types of obsessions and compulsions. One example is an excessive fear of germs and the compulsion to repeatedly wash the hands to ward off infection.

The person usually recognizes that the behavior is excessive or unreasonable.

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.

Questionnaires, such as the Yale-Brown Obsessive Compulsive Scale (YBOCS), can help diagnose OCD and track the progress of treatment.
