Screening for early signs of Parkinson's Disease
Official title: Prodromal Alpha-Synuclein Screening in Parkinson's Disease Study
Run by University Hospital Schleswig-Holstein · NCT04724941 · Data updated 2026-11-12
This study is trying to find early signs of Parkinson's Disease in people who might be at higher risk and will follow them for five years to learn more about how the disease develops.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 50 to 99 who are at increased risk for developing Parkinson's Disease but do not currently have the condition.
✕Probably not a fit
Patients with existing Parkinson's Disease or significant neurological diseases may not benefit from this study.

What this trial studies
The PASS-PD study aims to screen individuals at increased risk for developing Parkinson's Disease (PD) from the general population and follow them over five years. It focuses on understanding risk profiles, identifying individuals likely to develop PD, and exploring the role of biological markers in predicting disease progression. The study also emphasizes ethical standards for early risk disclosure and aims to provide detailed clinical phenotyping, particularly regarding non-motor symptoms. No interventions will be administered, as this is an observational study.
Why it matters
Potential benefit: If successful, this study could lead to earlier identification and better management of individuals at risk for Parkinson's Disease.
How similar studies have gone: Other studies have shown promise in identifying risk factors for Parkinson's Disease, but this approach focusing on prodromal screening is relatively novel.
