The Neural Basis of Postural Instability Gait Disorder Subtype of Parkinson's Disease: A <scp>PET</scp> and <scp>fMRI</scp> Study

Abstract

The involvement of the caudate, FG, and prefrontal-parietal network may be associated with the prominent gait impairments of PIGD subtype. Our findings expand the pathophysiological knowledge of PIGD subtype and provide valuable information for potential neuromodulation therapies alleviating gait disorders.
