Secrets of Superagers: How They Keep Sharp Memories and Brain Health

Research on superagers—people over 80 with memory performance similar to much younger individuals—reveals they have unique brain features such as higher levels of von Economo neurons, less cortical thinning, and fewer neurofibrillary tangles, which may contribute to their resistance to typical age-related cognitive decline. These findings could inform strategies to promote healthy brain aging, though more research is needed.
