Flowchart showing the selection of the subjects. From the initial 21 selected Prodromals (PROD) with at least one diffusion MRI (dMRI) scan, we used a 1:2 matching strategy to find the two most similar Parkinson’s disease (PD) and Control (CNT) subject for each PROD according to age, gender and time between scans. From the 42 subjects in the CNT group we excluded 12. From the 21 subjects in the PROD group we excluded five. From the 42 subjects in the PD group we excluded 21. These exclusions left a total of 30 CNT subjects, 16 PROD subjects, and 21 PD subjects.
