9. What is obsessive-compulsive disorder (OCD)?
People with obsessive-compulsive disorder (OCD) feel the uncontrollable need to check things over and over, or they may have certain thoughts or perform certain routines over and over. The thoughts and rituals of OCD cause distress and get in the way of daily life.
The repeated, upsetting thoughts of OCD are called obsessions. To try to control them, people with OCD repeat rituals or behaviors, which are called compulsions. People with OCD can't control these thoughts and rituals.
