Exceptional Memory Was Not Just an Absence of Alzheimer's Risk
SuperAgers and cognitively average peers could not be separated by APOE or current polygenic risk scores.
Summary
SuperAgers and cognitively average peers could not be separated by APOE or current polygenic risk scores.
Researchers compared 142 SuperAgers with 89 cognitively average older adults across five North American sites. APOE status, three Alzheimer's polygenic risk scores, and rare protective variants did not explain exceptional late-life memory. The result narrows one hypothesis and redirects attention toward biological, behavioral, and social protective pathways; it does not identify what preserves memory.
Why it matters
SuperAgers and cognitively average peers could not be separated by APOE or current polygenic risk scores.
Limits and context
- APOE status, three Alzheimer's polygenic risk scores, and rare protective variants did not explain exceptional late-life memory.
- The result narrows one hypothesis and redirects attention toward biological, behavioral, and social protective pathways; it does not identify what preserves memory.
