Obsessive Compulsive Disorder (OCD) is an anxiety disorder, which is characterized by unwelcome involuntary thoughts that result in apprehension, fear, and worry and/or repetitive behaviors otherwise aimed at reduction of the associated anxiety. While an obsession is generally associated with something pleasant and enjoyable, the obsession in case of OCD may be frightening and unpleasant.

The symptoms of OCD include repetitive checking; excessive cleaning or washing; extreme hoarding; nervous rituals like performing an activity several times before proceeding; and preoccupation with religious, sexual and violent thoughts. These symptoms are often time consuming and irritating and can result in financial as well as economic distress.

OCD sufferers are known to be above-average intelligent, tend to have an eye for details, avert risks, plan carefully and take some time to arrive at decisions. Biological and psychological factors are known to be behind the disorder.
