Obsessive-compulsive disorder (OCD) is an increasingly recognized disorder with a prevalence of 2-3% (Robins et al., 1984). Once thought to be psychodynamic in origin, OCD is now generally recognized as having a neurobiological cause. Although the exact pathophysiology of OCD in its pure form remains unknown, there are numerous reports of obsessive-compulsive symptoms arising in the setting of known neurological disease. In this paper, we review the reported cases of obsessive-compulsive symptoms associated with neurologic diseases and outline the known facts about the underlying neurobiology of OCD. Finally, we synthesize these findings into a proposed theory of the pathophysiology of OCD, in both its pure form and when it accompanies other neurological illness. |
