This study compared the performance of Parkinon's disease (PD) patients with and without depression, patients with depression alone, and normal control subjects on a cognitive screening instrument, the Mattis Dementia Rating Scale (DRS) to evaluate the influences of depression and Parkinson's disease on cognition. PD affects overall level of cognitive functioning and, to a lesser extent, DRS Initiation/Perseveration, Construction, and Attention. Diminished memory was primarily related to depression. Treatment of depression may ameliorate aspects of cognitive dysfunction in the PD patient with depression.
