DO YOU REALLY need to walk 10,000 steps a day to see results? When it comes to the brain, scientists are now saying you don’t. In fact, a study published earlier this week in Nature Medicine calculated the minimum you need to walk to lower your Alzheimer’s disease risk. Those steps may also explain why some people develop the disease at a faster rate than others.
“This sheds light on why some people who appear to be on an Alzheimer’s disease trajectory don't decline as quickly as others,” says Jasmeer Chhatwal, MD, PhD, a neurologist at the Mass General Brigham department of neurology and senior study author. “Lifestyle factors appear to impact the earliest stages of Alzheimer's disease, suggesting that lifestyle changes may slow the emergence of cognitive symptoms if we act early.”
