  1. Data are shown as mean ± SD or median (minimum–maximum). Age at death is shown in years, disease duration in months and post-mortem interval in hours. LPC stage is shown numerically; 0, non-αSyn; 1, olfactory-only; 2, amygdala-predominant; 3, brainstem-predominant; 4, limbic; 5, neocortical.
  2. ALS amyotrophic lateral sclerosis, FTLD frontotemporal lobar degeneration, LB Lewy bodies, LPC Lewy pathology consensus criteria, MS multiple sclerosis, MSA-c multiple system atrophy cerebellar variant, MSA-p multiple system atrophy predominant parkinsonism.
