  1. PMI post-mortem interval. Data summarised as mean ± SD. α-synuclein Braak score (ranging from 1 to 6) based on Braak et al., 2003, Neurobiol Aging. Tau pathology Braak score (ranging from 1 to 6) based on Braak et al., 1991, Acta. Neuropathologica. Score for neuronal loss is semi-quantitative with 0 = no loss and 4 = extreme loss. aDisease duration not available for 3 cases in 70s PD cohort, and 1 case in 80s PD cohort
