Walking 3,000 steps daily may slow Alzheimer's tau protein buildup, study finds
New research tracking nearly 300 older adults with early Alzheimer's signs for 9-11 years found that walking just 3,000 steps daily was linked to reduced tau protein buildup and nearly half the cognitive decline, though it didn't affect amyloid levels. The findings suggest even low levels of physical activity could protect the brain from Alzheimer's progression.
