Information for Patients

Obsessive-Compulsive Disorder

Also called: OCD

Obsessive-compulsive disorder (OCD) is a type of anxiety disorder. If you have OCD, you have frequent, upsetting thoughts called obsessions. To try to control the thoughts, you feel an overwhelming urge to repeat certain rituals or behaviors. These 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. With OCD, the thoughts and rituals cause distress and get in the way of your daily 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 include therapy, medicines, or both. One type of therapy, cognitive behavioral therapy, is useful for treating OCD.

Obsessive-compulsive disorder Obsessive-compulsive disorder (OCD) is a mental health condition characterized by features called obsessions and compulsions. Obsessions are intrusive thoughts, mental images, or urges to perform specific actions. While the particular obsessions vary widely, they often include fear of illness or contamination; a desire for symmetry or getting things "just right;" or intrusive thoughts involving religion, sex, or aggression. Compulsions consist of the repetitive performance of certain actions, such as checking or verifying, washing, counting, arranging, acting out specific routines, or seeking assurance. These behaviors are performed to relieve anxiety, rather than to seek pleasure as in other compulsive behaviors like gambling, eating, or sex.While almost everyone experiences obsessive feelings and compulsive behaviors occasionally or in particular contexts, in OCD they take up more than an hour a day and cause problems with work, school, or social life. People with OCD generally experience anxiety and other distress around their need to accommodate their obsessions or compulsions.About half the time, OCD becomes evident in childhood or adolescence, and most other cases appear in early adulthood. It is unusual for OCD to start after age 40. It tends to appear earlier in males, but by adulthood it is slightly more common in females. Affected individuals can experience periods when their symptoms increase or decrease in severity, but the condition usually does not go away completely.Some people with OCD have additional mental health disorders such as generalized anxiety, depression, phobias, panic disorders, or schizophrenia. OCD can also occur in people with other neurological conditions such as Tourette syndrome and similar disorders, traumatic brain injury, stroke, or dementia.
