The more exercise in mid- and late-life, the less Alzheimer's and all-cause dementia, adjusted for all known risk factors. Interestingly, the main take aways were :
• Staying active in midlife can cut your dementia risk by up to 40%. More activity, bigger benefit.
• Late-life exercise also helps: the most active older adults showed a similar drop in dementia risk.
• Early adulthood exercise alone didn’t show strong protection. Midlife and later years matter most.
• Benefits were seen across activity types and intensities. Moving regularly is what matters.
• Keeping up physical activity as you age may be one of the most powerful steps you can take for brain health.
