Obsessive compulsive disorder

People with obsessive compulsive disorder (OCD) are plagued with constant unwelcome thoughts - they may be obsessed with the idea that germs are everywhere, for example. Even if they know they are being irrational, they feel compelled to repeat some action over and over again, like constant cleaning or hand washing. Others feel they must check things repeatedly, perhaps before leaving the house.

People with OCD may feel compelled to perform a certain action to cope with their obsession.
