Could exercise help prevent dementia? A new Johns Hopkins Bloomberg School of Public Health-led study says yes.

Regardless of age and physical limitations, any movement could reduce dementia risk. According to a press release, the findings show that 35 minutes of weekly “moderate to vigorous physical activity” lowered dementia risk by 41%. The longer people engage in physical activity, the lower their dementia risk is. “Dementia risks were 60% lower in participants in the 35 to 69.9 minutes of physical activity/week category; 63% lower in the 70 to 139.9 minutes/week category; and 69% lower in the 140 and over minutes/week category.”

The study is published in the Journal of the American Medical Directors Association.
