Abstract

Sentence production in Parkinson’s disease (PD) has not been well described in the literature. 20 non-demented persons with PD and 20 healthy age-matched controls completed several cognitive tests and two experimental language tasks (sentence repetition and picture description). The stimuli were designed to vary in conceptual and grammatical complexity. Responses were scored on four error types: 1) completeness; 2) fluency; 3) grammaticality; and 4) gist meaning. Significant main effects and interactions between task, error type, complexity, and group were found. Working memory impairment predicted quality of language output. Implications for researchers, clinicians, patients, and caregivers will be discussed.
