Demographic information and testing scores for the groups

	aMCI (N=61)	NC (N=62)	Total (N=123)
Sex (% females)	78.6%	80.6%	79.6%
Age (years)	82.43 (6.43)	77.18 (7.80)	79.78 (7.59)
Education (years)	15.34 (2.82)	15.45 (2.57)	15.40 (2.69)
WRAT-3 Reading	0.62 (0.34)	0.51(0.40)	0.56 (0.38)
BVMT-R Delayed Recall	−2.05 (1.05)	−0.15 (0.99)	−1.09 (1.39)
HVLT-R Delayed Recall	−1.46 (1.08)	0.15 (0.84)	−0.64 (1.25)
RBANS Delayed Memory Index	−0.60 (0.99)	0.41 (0.63)	−0.09 (0.97)
Baseline Memory Composite	−1.36 (0.70)	0.14 (0.56)	−0.60 (0.98)
One-Year Memory Composite	−1.05 (0.92)	0.17 (0.93)	−0.46 (1.11)

Note. With the exception of Sex, all values are means and standard deviations. All cognitive scores are expressed as z-scores (M=0.0, SD=1.0). aMCI = amnestic Mild Cognitive Impairment. NC = normal comparison subjects. Total = both groups combined. WRAT-3 = Wide Range Achievement Test – Third Edition. BVMT-R = Brief Visuospatial Memory Test – Revised. HVLT-R = Hopkins Verbal Learning Test – Revised. RBANS = Repeatable Battery for the Assessment of Neuropsychological Status. The Memory Composite scores are the average of the age-corrected z-scores for RBANS Delayed Memory Index, BVMT-R Delayed Recall, and HVLT-R Delayed Recall.
