About the study
Parkinson's disease, a common movement disorder that results from a breakdown in the brain, often leads to challenges with talking, but less is known about the relationship between difficulties with talking and difficulties with learning to understand speech. By linking these two abilities in individuals with Parkinson's disease using a precision medicine approach, this project seeks to build a basis for new therapies that help people with Parkinson's disease both understand better and speak more clearly.
