NCT ID NCT02038608
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used PET scans to examine brain changes in people with Parkinson's disease at different stages. Researchers looked at two brain chemical systems—dopamine and serotonin—to understand non-motor symptoms like mood and thinking problems. 49 participants, including healthy volunteers, were involved. The goal was to learn how these systems change over time, not to test a treatment.
