This study delineates a comprehensive knowledge structure of GABA and PD research. Enhanced collaboration among authors across institutions and countries is pivotal to advancing the field. The mechanism of GABA in the basal ganglia region is a focus of current research. The detrimental effects of α-synuclein and oxidative stress on the GABAergic system and the non-motor symptom of anxiety are likely to be the frontiers of future research.
