摘要:
Introduction: Harboring two copies of the apolipoprotein E (APOE) epsilon 2 allele strongly protects against Alzheimer's disease (AD). However, the effect of this genotype on gray matter (GM) volume in cognitively unimpaired individuals has not yet been described. Methods: Multicenter brain magnetic resonance images (MRIs) from cognitively unimpaired epsilon 2 homozygotes were matched (1:1) against all other APOE genotypes for relevant confounders (n = 223). GM volumes of epsilon 2 genotypic groups were compared to each other and to the reference group (APOE epsilon 3/epsilon 3). Results: Carrying at least one epsilon 2 allele was associated with larger GM volumes in brain areas typically affected by AD and also in areas associated with cognitive resilience. APOE epsilon 2 homozygotes, but not APOE epsilon 2 heterozygotes, showed larger GM volumes in areas related to successful aging. Discussion: In addition to the known resistance against amyloid-beta deposition, the larger GM volumes in key brain regions may confer APOE epsilon 2 homozygotes additional protection against AD-related cognitive decline.
