Given the key role of attention in overall cognitive abilities, the substantial evidence that risk for cognitive impairment is increased by having the APOE e4 allele, and that APOE effects differ by sex and by racial/ethnic status, we investigated the effects of these factors on age-related trajectories of attention in a longitudinal study of older adults.
