Superagers maintain exceptional memory by growing new hippocampal neurons at twice the rate of their peers.

Summary: Some people in their 80s have memories as sharp as those in their 20s. A landmark study reveals their secret: adult neurogenesis. Researchers found that “superagers” have brains that are significantly more “neuronally fertile” than their peers. While neurogenesis—the growth of new brain cells—typically slows with age, superagers produce new neurons in the hippocampus at twice the rate of healthy older adults. In contrast, individuals with Alzheimer’s disease showed almost no new neuron growth, suggesting that this “resilience signature” is a primary defense against cognitive…
