This pilot study evaluated neuropsychological dysfunction in obsessive-compulsive disorder (OCD) and Parkinson's disease (PD). Both OCD and PD patients had impairment on visuoconstructional tasks but not on tasks of immediate memory and focused attention, suggesting common selective deficits in these two disorders with basal ganglia involvement.
