Abstract Background As longevity increases and the population over age 65 expands, advancing age remains the most reliable predictor of cognitive decline, highlighting the need to identify biological mechanisms that support exceptional cognitive aging. We tested whether lower inherited risk of Alzheimer’s disease (AD) dementia predicts SuperAger status (adults ≥ 80 years with episodic memory at least as good as middle-age adults) using prospectively enrolled SuperAgers and Cognitively Average Controls (Controls) from the multisite SuperAging Research Initiative. Methods We studied 231 participants (SuperAgers n = 142; Controls n = 89). We confirmed that the genetic ancestry structure across groups was comparable. We evaluated whether APOE status (ε2, ε3, ε4) and three AD polygenic risk scores (PRS) derived from large contemporary Genome-Wide Association Studies (GWAS) (PRSLambert, PRSWightman, PRSBellenguez) predicted SuperAging status using logistic regression models adjusted for age, sex, and education, considering ancestry interactions. Results APOE allele and genotype distributions did not differ between groups, and neither APOE nor any of the three PRS predicted SuperAger status. Results were unchanged when accounting for global non-European or African ancestry or principal components. In this well-characterized cohort, neither APOE nor contemporary PRS explained SuperAger status. Conclusions These findings suggest that the exceptional late-life memory phenotype that is characteristic of SuperAging is not explained by common-variant AD genetic risk captured by APOE or contemporary AD PRS, motivating a deeper investigation of potential rare genetic variations and experiential factors contributing to exceptional cognitive aging.
