NCT ID NCT02763683
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses brain imaging (PET scans) and memory tests to understand why some people with Parkinson's disease develop dementia. Researchers will follow 320 participants over several years, using scans to look for abnormal proteins and track thinking changes. The goal is to identify those at risk and distinguish different causes of dementia.
