A new study suggests daily walking can significantly reduce cognitive decline, particularly in individuals with a genetic predisposition to Alzheimer's disease. Researchers tracked nearly 3,000 participants aged 70-79 over 10 years, finding that those maintaining or increasing walking habits showed improved processing speed and executive function. The benefits were most pronounced in those with the APOE4 gene, which increases Alzheimer's risk. While the exact mechanism is unclear, theories involve increased BDNF production and reduced neuroinflammation. Experts emphasize that any amount of walking is beneficial, and a consistent routine is key to mitigating cognitive decline.
