Key result
APOE E4 carriers with age-associated memory impairment exhibited worse memory performance, but this negative cognitive effect was exclusively observed in females.
Why the study?
Does APOE E4 carrier status affect memory performance differently by gender in individuals with age-associated memory impairment?
Does APOE E4 carrier status affect memory performance differently by gender in individuals with age-associated memory impairment?
APOE E4 carrier status is associated with worse memory performance specifically in females with age-associated memory impairment.
Answers are grounded in this paper and cite their sources.
APOE E4 may impair memory only in females with age-associated impairment; hypothesis-generating and should not yet change practice.
Among 100 individuals with age-associated memory impairment (AAMI), APOE E4 carriers performed worse on memory. However, when subjects were considered by gender, this effect was only observed in females. APOE E4 may have a more robust cognitive influence on female than on male individuals with AAMI.

Bartrés‐Faz et al. (2002) studied this question. APOE E4 carriers with age-associated memory impairment exhibited worse memory performance, but this negative cognitive effect was exclusively observed in females.
