Over 2.2 million Americans suffer from obsessive compulsive disorder each year.

Everyone double checks things sometimes. But people with Obsessive Compulsive Disorder (OCD) feel the need to check things repeatedly, or have certain thoughts or perform routines and rituals over and over. The thoughts and rituals associated with OCD cause distress and get in the way of daily life.

The frequent upsetting thoughts are called obsessions. To try to control them, a person will feel an overwhelming urge to repeat certain rituals or behaviors called compulsions. People with OCD can't control these obsessions and compulsions.

For many people, OCD starts during childhood or the teen years. Most people are diagnosed by about age 19. Symptoms of OCD may come and go and be better or worse at different times.

What are the signs and symptoms of OCD?

People with OCD generally:

  • Have repeated thoughts or images about many different things, such as fear of germs, dirt, or intruders; acts of violence; hurting loved ones; sexual acts; conflicts with religious beliefs; or being overly tidy
  • Do the same rituals over and over such as washing hands, locking and unlocking doors, counting, keeping unneeded items, or repeating the same steps again and again
  • Can't control the unwanted thoughts and behaviors
  • Don't get pleasure when performing the behaviors or rituals, but get brief relief from the anxiety the thoughts cause
  • Spend at least 1 hour a day on the thoughts and rituals, which cause distress and get in the way of daily life.
What causes OCD?

OCD sometimes runs in families, but no one knows for sure why some people have it, while others don't. Researchers have found that several parts of the brain are involved in fear and anxiety. By learning more about fear and anxiety in the brain, scientists may be able to create better treatments. Researchers are also looking for ways in which stress and environmental factors may play a role. OCD is generally treated with psychotherapy, medication, or both.
