Eye-based test to measure brain dopamine in Parkinson's
Treatments studied
Part of Brain & nervous system clinical trials.
This study looks at how the brain's dopamine system works in people with Parkinson's disease by measuring signals from the eyes. It may help find a simple way to track the disease, which could lead to better care.
Summary written for real people, not researchers, by Clin2.
