Note. All values given in mean ± standard deviation. AD = Alzheimer's disease, CDR = clinical dementia rating scale (Hughes et al., 1982), f = female, FTLD = frontotemporal lobar degeneration, m = male, MMSE = Mini-Mental State Examination (Folstein et al., 1975), n = total number.
As tested with One-Way ANOVA: F, degrees of freedom (df), p.
As tested with two-tailed chi-square test: chi-square, df, p.
