Obsessive-compulsive disorder

Obsessive-compulsive neurosis; OCD

Last reviewed: February 26, 2013.

Obsessive-compulsive disorder (OCD) is an anxiety disorder in which people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them feel driven to do something (compulsions).

Often the person carries out the behaviors to get rid of the obsessive thoughts. But this only provides temporary relief. Not doing the obsessive rituals can cause great anxiety.

Causes, incidence, and risk factors

Doctors do not know the exact cause of OCD. Factors that may play a role include head injury, infections, and abnormal function in certain areas of the brain. Genes (family history) seems to play a strong role.

Most people who develop it show symptoms by age 30.

Symptoms

  • Obsessions or compulsions that are not due to medical illness or drug use
  • Obsessions or compulsions that cause major distress or interfere with everyday life

There are many types of obsessions and compulsions. Examples include:

  • Checking and rechecking actions (such as turning out the lights and locking the door)
  • Excessive counting
  • Excessive fear of germs
  • The compulsion to repeatedly wash the hands to ward off infection

The person usually recognizes that the behavior is excessive or unreasonable.

Signs and tests

Your own description of the behavior can help diagnose the disorder. A physical exam can rule out physical causes. A mental health assessment can rule out other mental disorders.

Questionnaires can help diagnose OCD and track the progress of treatment.

Treatment

OCD is treated using a combination of medication and behavioral therapy.

Medicines used include antidepressants, antipsychotics, and mood stabilizers.

Talk therapy (cognitive behavioral therapy; CBT) has been shown to be effective for this disorder. During therapy, the patient is exposed many times to a situation that triggers the obsessive thoughts, and learns to gradually tolerate the anxiety and resist the urge to do the compulsion. Therapy can also be used to reduce stress and anxiety and resolve inner conflicts.

Expectations (prognosis)

OCD is a long-term (chronic) illness with periods of severe symptoms followed by times of improvement. A completely symptom-free period is unusual. Most people improve with treatment.

Complications

Long-term complications of OCD have to do with the type of obsessions or compulsions. For example, constant handwashing can cause skin breakdown. OCD does not usually progress into another disease.

Calling your health care provider

Call for an appointment with your health care provider if your symptoms interfere with daily life, work, or relationships.
