Abstract
OBJECTIVE: We hypothesized the association of metabolic profile on cognition in postmenopausal women will be greater among ApoE4 carriers compared with noncarriers. METHODS:Metabolic biomarkers and measures of global cognition, executive functions, and verbal memory, collected among postmenopausal females, were used in this analysis. Clustering analyses of metabolic biomarkers revealed three phenotypes: healthy, predominantly hypertensive, and poor metabolic with (borderline normal laboratory values). General linear models tested whether an association of metabolic cluster with cognition differed by ApoE4 genotype. RESULTS: In the total sample of 497 women, verbal memory was lower in the poor metabolic cluster (P = 0.04). Among ApoE4+ women, performance in all cognitive domains was lowest in the poor metabolic cluster. Differences in executive functions among metabolic clusters were detected only in ApoE4+ women (P value for interaction = 0.003). CONCLUSIONS: In a general population of postmenopausal women, association between poor metabolic profile with reduction in cognitive performance is more apparent in women who carry an ApoE4 allele. These data indicate a window of opportunity for interventions to reverse the trajectory of the preclinical phase of Alzheimer's disease.
