What causes Obsessive Compulsive Disorder or OCD?

There is growing evidence that OCD represents abnormal functioning of brain circuitry, most likely involving a part of the brain called the striatum. OCD is not caused by family problems or attitudes learned in childhood, such as an inordinate emphasis on cleanliness, or a belief that certain thoughts are dangerous or unacceptable.

Research does indicate that OCD can run in families, suggesting that there may be a genetic link to the disease.

Brain imaging studies using a technique called positron emission tomography (PET) have compared people with and without OCD. Those with OCD have patterns of brain activity that differ from people with other mental illnesses or people with no mental illness at all. In addition, PET scans show that in patients with OCD, both behavioral therapy and medication produce changes in the striatum.
