Summary

This study is testing a new blood test to help doctors diagnose Parkinson's disease and similar brain disorders more accurately and earlier. Researchers will use a technique called RT-QuIC to detect misfolded proteins in blood samples from 458 participants, including healthy people and those with Parkinson's or multiple system atrophy. The goal is to develop a less invasive and more reliable diagnostic tool than current methods, which often require a brain autopsy after death for a definitive diagnosis.
