Study data characteristics.

Characteristics	Cognitive normal (CN)	Early MCI (EMCI)	Late MCI (LMCI)	Alzheimer's Disease (AD)	P value
Number of subjects ()	125	114	91	55
Age (Years)					<0.001
Gender (male/female)	58/67	62/52	48/43	32/23	0.442
Education (years)					0.720
CDRSb					<0.001
RAVLT					<0.001
MMSE					<0.001
TIV (mL)					0.123

Unless otherwise noted, data are presented as mean S.D.
P value based on Student’s -test between CN and AD unless otherwise specified and those less than significance level 0.05 are bolded.
A Fisher’s exact test was performed, and P value shows that gender effect is not significant at significance level of 0.05.
