The family often has a difficult time accepting the fact that the person with OCD cannot stop the distressing behavior. Family members may show their anger and resentment, resulting in an increase in the OCD behavior. Or, to keep the peace, they may assist in the rituals or give constant reassurance. Education about OCD is important for the family. Self-help books are often a good source of information.
Some families seek the help of a family therapist who is trained in the field.
Also, in the past few years, many families have joined one of the educational support groups that have been organized throughout the country. There is growing evidence that OCD represents abnormal functioning of brain circuitry, probably 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. 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.
