    Is impairment of inflectional morphological processes with Parkinson’s patients procedural or executive or both ?
    2012, Vol. XVII-2, pp. 101-115

    Parkinson's disease is a neurodegenerative neurological condition characterized by motor deficits but also by cognitive deficits affecting working memory, declarative memory and attentional capacities. With respect to language, the disease is also marked by the impairment of inflectional morphological processes. In this article, we present and discuss the respective supports to the procedural and executive functional origin of inflectional morphology impairment in Parkinson's disease. We also report the results from a recent study, conducted with 15 individuals with PD, suggesting a contribution, non-exclusive to language, of basal ganglia to executive processes involved in inflectional morphology.
