Superagers Do Not Simply Inherit Less Alzheimer's Risk
A genomic comparison found that extraordinary late-life memory cannot be explained by carrying fewer common risk variants.
Summary
A genomic comparison found that extraordinary late-life memory cannot be explained by carrying fewer common risk variants.
Researchers comparing so-called superagers with other older adults found that their inherited burden of common Alzheimer disease risk variants was broadly typical rather than unusually low. The result narrows one explanation for why some people retain exceptional memory into advanced age and redirects attention toward protective biology, life history or combinations not captured by standard risk scores. It does not identify a longevity gene or a way to manufacture superaging.
