  • An anxiety disorder characterized by recurrent, persistent obsessions or compulsions. Obsessions are the intrusive ideas, thoughts, or images that are experienced as senseless or repugnant. Compulsions are repetitive and seemingly purposeful behavior which the individual generally recognizes as senseless and from which the individual does not derive pleasure although it may provide a release from tension.
  • An anxiety disorder in which a person has intrusive ideas, thoughts, or images that occur repeatedly, and in which he or she feels driven to perform certain behaviors over and over again. For example, a person may worry all the time about germs and so will wash his or her hands over and over again. Having an obsessive-compulsive disorder may cause a person to have trouble carrying out daily activities.
  • Anxiety disorder characterized by recurrent, persistent obsessions or compulsions: obsessions are the intrusive ideas, thoughts, or images that are experienced as senseless or repugnant; compulsions are repetitive and seemingly purposeful behavior which the individual generally recognizes as senseless and from which the individual does not derive pleasure although it may provide a release from tension.

  • Obsessive-compulsive disorder (ocd) is a type of anxiety disorder. If you have ocd, you have repeated, upsetting thoughts called obsessions. You do the same thing over and over again to try to make the thoughts go away. Those repeated actions are called compulsions. Examples of obsessions are a fear of germs or a fear of being hurt. Compulsions include washing your hands, counting, checking on things or cleaning. Untreated, ocd can take over your life.researchers think brain circuits may not work properly in people who have ocd. It tends to run in families. The symptoms often begin in children or teens. Treatments that combine medicines and therapy are often effective.
