Brain scans reveal hidden clues in Parkinson's
NCT ID NCT02038608
First seen Jan 10, 2026 · Last updated May 22, 2026 · Updated 16 times
Summary
This study looked at 49 people with Parkinson's disease and healthy volunteers to understand how changes in two brain chemicals—dopamine and serotonin—relate to both movement and non-movement symptoms. Using special PET scans, researchers compared people at early, middle, and late stages of the disease. The goal was to learn more about how these brain systems break down over time, not to test a new treatment.
