Why do some people's memories stay sharp as they age?
Briefly

As humans age, brain function typically declines, leading to challenges in learning and memory due to shrinkage in healthy brains. However, a distinct group known as "SuperAgers" experiences a slower rate of brain shrinkage, allowing them to retain memory abilities similar to those of individuals aged 50 to 60. Research from Northwestern University's SuperAging Program has identified key factors contributing to this resilience in memory function among older adults. The findings capture insights gathered over a span of 2.5 decades, revealing the unique cognitive strengths of SuperAgers and their aging process.
The human brain tends to slow down as we age; even healthy brains shrink, making learning and memory harder.
Some people's brains shrink more slowly than their peers, and they're called "SuperAgers." They're aged 80 or older with the memory abilities of someone 50-to-60 years old.
