Summary
A recent study by Stony Brook Medicine in New York found that older adults who walk at a faster pace, known as “super movers,” have a lower risk of cognitive decline. The study evaluated 4,000 adults over 80 and found that 6-10% were super movers, who walked at speeds comparable to people three decades younger. These individuals had about half the risk of cognitive decline compared to seniors with typical gait speed. The study suggests that preserving mobility may be an important marker of healthy brain aging and resilience.

The advice sounds familiar.
This study adds to the growing evidence that physical activity is beneficial for brain health. The finding that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers suggests that they may possess resilience mechanisms that help preserve brain function. The study’s lead author, Dr. Joe Verghese, notes that understanding these resilience factors could lead to new strategies for promoting healthy brain aging. However, he also emphasizes that walking speed is best viewed as a marker of overall health, not a treatment.
The study’s findings are observational, and it does not prove that walking faster prevents dementia. Other factors, such as cardiovascular health, physical fitness, or genetics, may also contribute to both faster walking and better cognitive outcomes.
As the study’s lead author notes, “The broader message is that physical activity is important at any age.” Any activity is beneficial if it’s done regularly and with the right intensity.
It’s worth noting that major public health guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.
Perhaps the most intriguing finding is that the super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
