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, are rewriting what we thought was possible for the aging brain. With memory abilities comparable to people decades younger, their brains either resist or withstand the damage typically linked to Alzheimer’s disease. Decades of research reveal that their social lifestyles and unique brain biology may hold the key to preserving cognitive function. Scientists believe these insights could pave the way for new strategies to delay or even prevent dementia. These individuals consistently perform on memory tests at levels similar to people at least 30 years younger, challenging the long-standing belief that cognitive decline is unavoidable with age. Over decades of research, scientists have noticed some ... [4283 chars]
