Researchers have made a groundbreaking discovery about the genetic advantages of 'super agers', individuals aged 80 or older who still possess memories as sharp as those in people decades their junior. Contrary to popular belief that age is a determining factor for cognitive decline, super agers continue to thrive even at centenarian levels, with many maintaining active social networks and rigorous physical activity regimens.
According to a recent study published by the Alzheimer's Association, super agers also possess two distinct genetic traits that confer an enhanced resistance to Alzheimer's disease. By analyzing data from 18,000 individuals involved in a separate Alzheimer's Disease study, Vanderbilt University researchers identified 1,623 super agers and compared their genetic profiles to those of people with Alzheimer's and age-matched control groups.
The study revealed that super agers are significantly less likely to carry the APOE-ε4 gene, which puts individuals at an elevated risk of developing Alzheimer's. In fact, they were 68% less likely to harbor this gene compared to those with Alzheimer's disease in the same age group. Moreover, they were also more than twice as likely to possess the protective APOE-ε2 gene, which is known to shield against Alzheimer's development.
"These findings provide conclusive evidence that APOE contributes to SuperAging," said Leslie Gaynor, lead author of the study and clinical neuropsychologist at Vanderbilt University Medical Center. This groundbreaking research has significant implications for our understanding of aging and Alzheimer's disease, highlighting the importance of genetic factors in determining an individual's cognitive resilience with age.
