Abstract
Obsessive Compulsive Disorder is one of the increasing psychological disorders. If not detected early and treated properly, obsessive-compulsive disorder usually becomes an incapacitating illness adversely affecting almost all aspects of the patient`s life. Outpatient behavioral and pharmacotherapies frequently fail. This is a report on a severe case of obsessive-compulsive disorder that was treated as an in-patient with both behavior and pharmacotherapies, she was then followed up for 5 years with no relapse. The case reflects the importance and the need for in-patient units for severe resistant obsessive compulsive cases especially in Saudi Arabia where we have an increasing number of such cases.
