Summary

This observational study follows people with early Parkinson's disease, those at genetic risk, and healthy volunteers over time. Researchers collect clinical exams, brain scans, and biological samples (blood, spinal fluid, skin, stool) to identify markers that predict how the disease starts and progresses. The goal is to find reliable tools for future trials of treatments that could slow or stop Parkinson's.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could identify early warning signs and biomarkers for Parkinson's, enabling earlier diagnosis and better clinical trials for treatments.
What could go wrong
This is an observational study, not a treatment trial. It may not find clear predictive markers, and results may take years to translate into practical tests.
