  1. Data represent the mean and standard deviation (in parentheses) unless otherwise indicated. Pairwise comparisons were performed based on the two-sample t test (two-sided) for all measures except for gender where a Fisher exact test was used (significant result is highlighted with bold formatting).
  2. M/F male/female, AD Alzheimer’s disease group, MCI mild cognitive impairment, SMC significant memory concern, APOE4# the number of APOE ε4 carrying, CSF+ <192 ng/L, PET +  cortical Aβ > 0.872 SUVR.
