Key Points:
- SuperAgers, individuals in their 80s and 90s with exceptional cognitive abilities, produce twice as many young neurons as cognitively healthy adults and 2.5 times more than those with Alzheimer’s disease, indicating significant brain regenerative capacity.
- The study found that SuperAgers have a unique cellular environment in the hippocampus that supports neurogenesis, enhancing brain plasticity and resilience against aging and cognitive decline.
- SuperAgers exhibit thicker cingulate cortex and fewer tau tangles in the hippocampus, with larger and healthier neurons in critical brain areas like the entorhinal cortex, contributing to their superior memory and cognitive function.
- Lifestyle factors such as diet, exercise, stress reduction, and sleep optimization may promote brain
