Obsessive Compulsive Disorders (OCD) is a condition characterized by unwanted or intrusive and anxiety-provoking thoughts called obsessions, that often compel an individual to carry out repetitive actions, called compulsions, in order to reduce their anxiety. Common obsessive thoughts include a fear of contamination by germs or other contaminants, fear of harming oneself or others, and sexually explicit or violent images. While common compulsions include washing and cleaning, checking, repeating as well as mental compulsions.
