Walking 5000 steps a day may slow down the progression of Alzheimer's disease.

On November 6, a new 14-year follow-up study published in Nature Medicine showed that for older adults with normal cognitive function, walking more than 5000 steps per day could be an effective strategy to delay the progression of Alzheimer's disease. The study, for the first time, revealed through objective data that moderate exercise could significantly reduce the accumulation rate of tau protein in the brains of preclinical patients and slow cognitive decline. This discovery provides older adults with a clear and achievable exercise goal, and opens up new directions for early intervention in Alzheimer's disease.
