Neurological factors in obsessive compulsive disorder. Two case reports and a review of the literature.

Two patients are described in whom an obsessive-compulsive disorder began just after the onset of epilepsy. Neurological factors in OCD are then reviewed, and clinical reports of patients with OCD and co-existing brain pathology, EEG abnormalities, CT scan changes and electrical stimulation of the brain discussed. It is concluded that neurological factors are present in only a minority of cases of OCD. Successful behavioural treatment is independent of such factors.
