BackgroundParkinsons disease (PD) remains incurable, with a long prediagnostic phase currently undetectable by existing methods. Identifying individuals at high risk of PD would enhance our understanding of the underlying pathophysiology and will open up new preventive or early therapeutic avenues. MethodsIn the largest proteomic study in neurodegenerative diseases to date, we analyzed blood samples from [~]74,000 individuals across discovery and validation cohorts. In the discovery phase, we l...
