The symptoms of OCD vary widely from person to person. Without treatment, OCD can last for a lifetime.
Obsessive-compulsive disorder (OCD) is a common anxiety disorder. It causes unreasonable thoughts, fears, or worries. A person with OCD tries to manage these thoughts through rituals.
Rituals such as hand washing, counting, checking or cleaning are often performed in hope of preventing obsessive thoughts or making them go away. Performing these rituals, however, provides only temporary relief, and not performing them markedly increases anxiety. Left untreated, obsessions and the need to perform rituals can take over a person's life. OCD is often a chronic, relapsing illness.
