Overview
We aim to identify speech and language markers that provide information on cognitive function and predict cognitive decline in Parkinson's disease. We will administer various speech tasks and cognitive assessments to participants with Parkinson's disease and healthy controls. We will also explore the associations between genetic factors and speech and cognitive status in Parkinson's disease.
