Some people over the age of 80 manage to keep the memory and sharpness of someone decades younger. New research reveals what sets these “superagers” apart—and one surprising personality trait they all seem to share.
Outstanding memory performance
Superagers can recall far more information than their peers, such as remembering at least nine words from a list read to them 30 minutes earlier.
High levels of gregariousness
All superagers studied showed a strong tendency toward sociability, engaging actively with others and maintaining strong personal connections.
More von Economo neurons
These rare brain cells, linked to social behavior and emotional processing, were found in higher numbers than in younger individuals.

Thicker anterior cingulate gyrus
This brain region, linked to motivation and persistence, was thicker in superagers, possibly aiding resilience in the face of challenges.
Slower cortical thinning
Their brains shrink at about half the rate of typical older adults, reducing vulnerability to diseases like dementia and Parkinson’s.
Stronger cholinergic system
Superagers maintain a robust neurotransmitter network that supports memory, learning, and alertness.
Slower breakdown of acetylcholine
Lower levels of the enzyme that degrades acetylcholine may help preserve cognitive function longer.

Healthy neurons despite disease markers
Some superagers’ brains show signs of Alzheimer’s pathology but still contain many viable neurons that help sustain memory.
Tenacity and autonomy
Their personality profiles suggest determination and a willingness to live life on their own terms, which may contribute to mental vitality.
Mixed lifestyle factors
Some lived traditionally healthy lives, others did not—suggesting genetics and brain structure may play as much of a role as habits.
