Demographical and clinical characteristics of the population

	Control subjects (n = 32)	bv-FTD (n = 32)	AD (n = 32)
Gender (male : female)	22 : 10	22 : 10	17 : 15
Age (years)	68.59 (1.27)	68.56 (1.19)	69.72 (1.27)
Education level (years)	7.06 (0.86)	6.97 (0.84)	6.91 (0.87)
MMSE (score)	29.06 (0.20)	26.88 (0.43)a	21.22 (0.70)a,b
CDR (score)	0 (0)	1 (0)	1 (0)

Note: bv-FTD = behavioral frontotemporal dementia; AD = Alzheimer's disease; MMSE = Mini-Mental State Examination; CDR = Clinical Dementia Rating.

Data are expressed as mean (SEM).

Comparisons between Controls- bv-FTD, Controls-AD, and bv-FTD-AD patients were carried out by a one-way ANOVA with post hoc Tukey tests, Kruskal–Wallis 1-way ANOVA for k samples with pairwise comparisons, or χ² test.

^aControls versus bv-FTD: p < .05; Controls versus AD: p < .001.
