(HealthDay News) -- Obsessive-compulsive disorder is characterized by repetitive, unwanted thoughts and irrational, excessive urges to complete certain actions.
People with OCD are often unable to stop the thoughts and behaviors without help, says the National Alliance on Mental Illness.
For many people with OCD, medicine and therapy are successful when used together. Most commonly, people get either exposure and response therapy or cognitive behavioral therapy. An antidepressant often is prescribed, as well.
