When dementia cases (n = 103) were included in the same analysis, the same associations were found: APOE ε4 and Logical Memory (F(1, 392) = 5.5, p = .02, ηp2 = 0.014); fitness and Verbal Fluency (F(1, 392) = 12.8, p < .001, ηp2 = 0.032); fitness and Raven’s Matrices (F(1, 392) = 13.6, p < .001, ηp2 = 0.034). This evidence concerns the gene APOE and dementia.
