Abstract

Traditionally, Parkinson’s disease was defined as presenting only motor deficits. However, recent studies have highlighted the effects of Parkinson’s disease on various language skills. The present study was designed to evaluate the performance of individuals with Parkinson’s disease on action verbs and tenses identification skill. 20 Kannada speaking healthy elderly individuals (10 Males; 10 Females) in the age range of 65 – 75 years and 10 Kannada speaking non-demented individuals with Parkinson’s disease (5 Males; 5 Females) in the age range of 65 – 75 participated in this study. The findings highlighted the language skills in individuals with Parkinson’s disease.

Keywords: Parkinson’s disease, Kannada speakers, action verbs and tenses

Introduction

Parkinson’s disease (PD) is a neurodegenerative disorder, caused by degeneration of midbrain dopaminergic neurons mainly in the substantia nigra and functional impairment of the basal ganglia. Motor symptoms of tremor, bradykinesia, and rigidity are the clinical hallmarks of PD (Wolters and Bosboom, 2007).

Several imaging studies have demonstrated that damage to frontostriatal circuits impact both language and cognitive functions. Crosson (1985) suggested that basal ganglia damage results in deficit of both motor programming and language formulation. Disruption of large cortico-striato-pallido-thalamocortical circuits impair aspects of language production is reported (Copland, Chenery, and Murdoch, 2000; Copland, 2003). Lieberman et al. (1992) reported that speech motor deficits accompanied the grammatical and cognitive deficits in PD patients. The common neurological basis for these deficits was suggested to be the disruption of the circuits between subcortical structures and prefrontal cortex.
