Using visual dysfunction to understand Parkinson’s disease

Parkinson’s is usually thought of as a disease affecting movement, but it can also cause problems with thinking and memory. It affects people in different ways, making it difficult to predict what will happen to an individual. We have developed sensitive visual tests for people with Parkinson’s disease to detect whether the thinking parts of the brain are involved.

Our group uses these sensitive visual tests, combined with brain imaging and retinal imaging to understand how cognition is affected in Parkinson’s disease.
