Obsessive-compulsive neurosis; OCD
Obsessive-compulsive disorder (OCD) is a mental disorder in which people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), and behaviors that drive them to do something over and over (compulsions).
Often the person carries out the behaviors to get rid of the obsessive thoughts. But this only provides short-term relief. Not doing the obsessive rituals can cause great anxiety and distress.
Health care providers 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. A history of physical or sexual abuse also appears to increase the risk for OCD.
Parents and teachers often recognize OCD symptoms in children. Most people are diagnosed by age 19 or 20, but some do not show symptoms until age 30.
People with OCD have repeated thoughts, urges, or mental images that cause anxiety. These are called obsessions.
They also perform repeated behaviors in response to their thoughts or obsessions. Examples include:
Not everyone who has habits or rituals they like to perform has OCD. But, the person with OCD:
People with OCD may also have a tic disorder, such as:
The diagnosis is made based on an interview of the person and family members. 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.
OCD is treated using a combination of medicine 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 person 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.
You can ease the stress of having OCD by joining a support group. Sharing with others who have common experiences and problems can help you not feel alone.
Support groups are usually not a good substitute for talk therapy or taking medicine, but can be a helpful addition.
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.
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 mental problem.
Call for an appointment with your provider if your symptoms interfere with daily life, work, or relationships.
