Abstract

Parkinson’s disease (PD), as a central nervous system disease affecting extrapyramidal system, typically manifests itself in motor deficits, but it is also characterized by a range of language disturbances in terms of articulation, lexicosemantics, syntax, pragmatics, and so on. This article, highlighting PD patients’ selective deficit (SD) in action semantics processing, offers a comprehensive review of the diverse accounts of SD, and attempts to characterize the controversy over the neurofunctional accounts of SD as Motor-cognition Dissociation View vs. Motor-cognition Coupling View. This paper also introduces the Compensatory Pathway Hypothesis and offers comments on future studies in this respect.

Key words

Parkinson’s disease (PD) / deficit in actions semantics processing / motor-cognition dissociation view / motor-cognition coupling view
