Subclinical Visuospatial Impairment in Parkinson’s Disease: The Role of Basal Ganglia and Limbic System

Abstract

We found that both loss of efficiency and compensatory mechanisms occur in PD patients, providing further insight into the pathophysiological role of the functional alterations of basal ganglia and limbic structures in the impairment of visuoperceptual and visuospatial functions observed in PD.
