Faster Walking Pace Linked to 50% Lower Cognitive Decline Risk in Adults Over 80
A new study found that adults over 80 who walk at a faster pace have a 50% lower risk of cognitive decline compared to slower walkers. Researchers say gait speed may be a simple, low-cost marker for brain health.
Adults over 80 who walk at a faster pace have a 50% lower risk of cognitive decline compared to those who walk slowly, according to new research published this week.
The study tracked gait speed in a large group of older adults over several years, measuring walking pace alongside cognitive assessments. Researchers found a consistent link between faster walking and better brain health outcomes, even after adjusting for other factors like age, education, and physical activity levels.
Gait speed has long been used as a general marker of physical health in older adults. This research adds to a growing body of evidence that it may also reflect brain health.
The mechanism is not fully understood. Some researchers believe that the same neurological systems that control movement also support cognitive function, so decline in one area may signal decline in the other. Others point to cardiovascular fitness as a shared factor.
Experts say the finding is practical. Walking pace is easy to measure in a clinical setting without expensive equipment. Doctors could use it as a screening tool to identify patients who may benefit from early cognitive evaluation.
The researchers stopped short of saying that walking faster causes better brain health. They noted that the relationship may run in both directions, with cognitive health also influencing how quickly people walk.
