Walking & Alzheimer's Risk
Walking even just 3,000 steps a day may lower the risk of Alzheimer's in older adults, according to new research. This benefit was also seen in older adults who already had high levels of amyloid-beta, a protein that may play a large role in the disease’s development. Researchers found that among older participants with higher levels of amyloid-beta, those who walked fewer than 3,000 steps a day showed quicker cognitive decline than those who walked 3,000 to 5,000 steps a day. Overall, the study discovered that participants who walked 3,000 to 5,000 steps per day slowed cognitive decline by an average of 3 years. Those who did 5,000 to 7,500 steps a day delayed cognitive decline by about 7 years.
