Scientists pinpoint how many steps per day may reduce Alzheimer’s risk

A 14-year study involving over 294 participants aged 50 to 90 found that walking more than 5,000 steps per day may be associated with a slower decline in cognitive abilities and a reduced buildup of amyloid and tau proteins in the brain, which are linked to Alzheimer's disease. The research, conducted by Harvard experts, analyzed data from individuals who had early signs of Alzheimer's pathology in their brains but were not yet experiencing symptoms. Even modest activity levels of 3,001 to 5,000 steps per day showed a notable slowing in tau accumulation and cognitive decline. However, the study suggests that 5,001 to 7,500 steps per day yielded more significant benefits in slowing these processes. While experts acknowledge the study's strengths, they also note that it cannot definitively prove causality or rule out other health factors influencing activity levels. Researchers emphasize that... download the app to read more
