Overview

• A study by Johns Hopkins University found that as little as five minutes of daily exercise can reduce the risk of dementia in older adults by 41%.
• The research involved nearly 90,000 participants aged 50 and above, using wrist accelerometers to measure physical activity levels objectively.
• The findings suggest that even small amounts of movement, such as 35 minutes of moderate exercise weekly, can provide significant cognitive benefits.
• Higher levels of physical activity further reduced dementia risk, with those exercising over 140 minutes weekly seeing a 69% lower risk.
• The study emphasizes that any amount of exercise, even for frail individuals, is better than none, offering an accessible prevention strategy for dementia.
