Walking speed may signal advanced aging, neurologists explain

The speed at which people walk may offer insights into their internal health, with research suggesting a link between slow walking and accelerated aging.

Academic evidence indicates that individuals who maintain a brisk pace tend to age less rapidly than those who stroll. Conversely, slower walkers often display signs of advanced cognitive aging. This includes lower scores on intelligence quotient tests, memory assessments, processing speed evaluations, and other mental function tests. Brain scans of slow walkers have revealed smaller brain sizes and a higher proportion of white matter, the crucial tissue connecting different brain areas.

Multiple studies confirm that gait speed is a significant predictor of life expectancy in older adults. For instance, a meta-analysis by the University of Pittsburgh, involving over 34,000 adults aged 65 and older, found a strong association between walking speed and longevity. Men aged 75 who walked slower had a 19% chance of living another decade, compared to 87% for those who walked faster.

More recent research published in the journal Neurology, which tracked 904 individuals from age 45 throughout their lives, also found that slow walkers showed signs of "accelerated aging" in their lungs, teeth, hearts, and immune systems. Brain imaging in this group revealed smaller brains, thinner neocortex, and less white matter, suggesting cognitive decline. These findings highlight how gait speed can serve as a simple yet powerful indicator of overall health and aging.
