Obsessive–compulsive disorder
anxiety disorder that involves unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them feel driven to do something (compulsions) / From Wikipedia, the free encyclopedia
Obsessive–compulsive disorder (OCD) is a mental disorder. It causes repeated and unwanted thoughts and/or feelings (obsessions). It causes repeated actions (compulsions).
Anxiety is one of the most common symptoms. It can lead the person to believe that if a task is not done, something bad will happen. Such a task may be washing hands many times, keeping the lights on, or keeping their surrounding clean. This belief leads to more anxiety and tension. The actions that someone takes to stop the thoughts and feelings may take more than an hour every day. Excessive hand washing is a sign of OCD.
OCD can limit one's ability to take part in relationships, the workplace, and in society in general. OCD affects about 2% of the world's population.[1][2] United States, about one in fifty adults has OCD.[3]
