The battle against cognitive decline is increasingly aided by an array of helpful tips. Articles encourage us to do crossword puzzles, maintain social connections and be thoughtful about what we eat. Sometimes, the number of things we should be doing to keep our wits about us can feel overwhelming.

Now, a new study from researchers at Mass General Brigham suggests a walk outside might be one of the best — and easiest — ways of ensuring we age gracefully, at least cognitively.

According to their findings, even a few thousand steps a day can be enough to help delay the progression of Alzheimer’s disease, especially in those most vulnerable to it.

Those who walked between 3,000 and 5,000 steps a day demonstrated around three years of delay in cognitive decline, while folks who hit step counts of 5,000 to 7,500 per day delayed their cognitive decline by seven-ish years.

In contrast, participants who moved less — and were more sedentary — showed a faster buildup of tau proteins in the brain. Accumulation of that pesky protein is associated with the progression of Alzheimer’s, as well as more rapid deterioration in thinking skills and daily functioning.

Next steps will include research to better understand the mechanics behind just how movement slows, or even prevents, cognitive decline — while also drilling into what kind of movement might be best. Then, scientists may be able to begin crafting exercise-based interventions for older adults.

It doesn’t make getting outside any easier, of course, but it’s certainly a good source of motivation … and a reason to get up and stretch your legs after that heavy holiday dinner.
