- These 80-year-olds have the memory of 50-year-olds. Scientists now know why
A rare group of adults over 80, known as SuperAgers, exhibit memory abilities comparable to those of 50-year-olds. Their brains resist Alzheimer’s-related damage, with social lifestyles and unique brain biology potentially preserving cognitive function. Scientists suggest these findings could lead to strategies for delaying or preventing dementia.
