| White race, n (%)a | 11 (91.7) | 10 (90.9) | 11 (84.6) | 18 (94.7) |
| Education, years | 18 (14–20) | 16 (15–18) | 18 (16–20) | 18 (16–19) |

Values for age indicate means ± standard deviations of the participants at the time of evaluation. Values for education indicate medians with interquartile ranges within parentheses.
aRace was self-reported and the total number of observations reported for each group included, n = 12, n = 11, n = 13 and n = 19 for lvPPA, nfvPPA, svPPA, and control groups, respectively.
One-way ANOVA and Dunnett’s post hoc comparison showed no significant difference of age between each patient group and the control group. Wilcoxon-Mann-Whitney test showed no significant difference of education between each patient group and the control group. Fisher exact test for sex, handedness, and race between each patient group and controls showed no statistical differences.
