Table 1

Condition	Number of Subjects	Male/ Female	Age (Years, Mean ±SD)	MMSE (Points, Mean ±SD)	Immuno positivity percentage (median, min -max)
Condition	Number of Subjects	Male/ Female	Age (Years, Mean ±SD)	MMSE (Points, Mean ±SD)	PHF	AT8
Healthy	17	6/11	72 ± 14	29.4 ±1.4	38(9-58)	0.6 (0.4-1.7)
Alzheimer´s disease	20	8/12	79 ± 9	14.5 ± 7.3^A	46(9-67)	4.6 (2.7-5.4)^A
Non-degenerative dementia	12	9/3	76 ± 13	17.2 ± 9.7^A	46 (18-58)	1.4 (0.3-1.7)^B

Table 1: Significant differences among groups were found in MMSE scores and % immunopositivity for AT8. ^Ap<0.001 as compared with the control group, ^Bp<0.001 as compared with the AD group. ANOVA followed by Tuckey test for the variables age and MMSE. Kruskal-Wallis followed by Mann-Whitney U-test for immunopositivity percentages.
