The approach is observational, enrolling up to 3,000 people diagnosed by standard criteria including the UK Brain Bank, and collecting clinical data and medical history over time so researchers can map patterns, progression, and potential biomarkers. Eligible participants are adults whose Parkinson's symptoms started at age 50 or younger, diagnosed by UKBB or equivalent criteria, and who do not have a family history of PD.
