Study demographics by cohort: Number of subjects (i.e., N); Age in years (mean and standard deviation, and range); MMSE score (with standard deviation); Gender (proportion of females); Years of Education (with standard deviation); Family history of AD (FHAD, number of cases); and APOE ε4 status (number of cases). T-tests and Fisher's exact tests were used to test for significant differences across groups; p values are reported on the far right column.
