NCT ID NCT02488395
First seen Nov 18, 2025 · Last updated Jun 17, 2026 · Updated 25 times
Summary
This study tested whether a brain scan (fMRI) could detect early signs of Parkinson's disease by measuring activity in a small brain area called the superior colliculus, which processes visual information. Researchers compared 23 newly diagnosed Parkinson's patients with healthy volunteers to see if differences in brain responses to light could serve as an early marker. The goal is to develop a tool for earlier diagnosis, potentially before symptoms become severe.
