3,000 or more steps to slower cognitive decline in older adults at increased risk of developing Alzheimer's disease

This observational study serves as preliminary research with inherent limitations—interventional studies are needed to establish causality. The findings show a correlation between physical activity and slower cognitive decline in individuals with high baseline beta-amyloid accumulation. The model was adjusted for sex, age, and demographics. This is a good study that provides rationale for an preventive interventional trial in this population.
