Aim: To assess cognitive function in subjects with clinically probable Parkinson's disease (PD). Methods: 44 patients with probable PD completed the CAMCOG, MMSE, Hamilton depression scale, visuospatial, frontal and memory tests. 36 patients underwent to SPECT study. Results: All patients showed different degrees of impairment in visuospatial and frontal functions. Poorer performance on the CAMCOG was related to age, illness duration, motor deficits and depressive symptomatology. Cortical hypometabolism was detected in 15 out of 36 patients and was related to the illness duration. Conclusions: Patients with Parkinson's disease should be investigated for neuropsychological and psychiatric functions because cognitive impairment and depressive symptoms are clinically relevant features of the disease.
