Brackets indicate [male/female]. The mean for each variable is given with standard deviations in parentheses

1

If the ANOVA F was significant (P < ,05), then the Tukey-Kramer post hoc pair-wise comparisons were performed and P values are given.

2

CERAD = Consortium to Establish a Registry for Alzheimer’s disease

3

Animal Fluency: 9 of the AD subjects did not complete/were not administered the test

4

Variances are not equal and differ significantly

5

WLM: 32 subjects (aMCI = 8; CON = 15; AD = 9) did not complete/were not administered the test

6

TMT-B 14 subjects (aMCI = 3; CON = 2; AD = 9) did not complete the test in the allotted timeframe. Scores for these subjects are not included in the TMT-B score
