Obsessive-Compulsive Disorder, OCD, is an anxiety disorder and is characterized by recurrent, unwanted thoughts (obsessions) and/or repetitive behaviors (compulsions). Repetitive behaviors such as handwashing, counting, checking, or cleaning are often performed with the hope of preventing obsessive thoughts or making them go away. Performing these so-called "rituals," however, provides only temporary relief, and not performing them markedly increases anxiety.
People with OCD may be plagued by persistent, unwelcome thoughts or images, or by the urgent need to engage in certain rituals. They may be obsessed with germs or dirt, and wash their hands over and over. They may be filled with doubt and feel the need to check things repeatedly.
