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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
