New study aims to spot Parkinson's early with simple blood, urine, and stool tests

NCT ID NCT07604883

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This observational study will enroll 200 people—100 with Parkinson's disease, 50 with related conditions, and 50 healthy controls—to find molecular markers in blood, urine, and stool that can distinguish Parkinson's from atypical parkinsonism. Participants provide samples and undergo clinical assessments at the start and after 12-18 months. No treatment is given, but the results may pave the way for earlier and more accurate diagnosis.

What this could lead to
If successful, this could lead to a simple, non-invasive test to diagnose Parkinson's disease earlier and more accurately.
What could go wrong
This is an early observational study, not a treatment trial. The biomarkers may not prove reliable enough for routine use.
