19-Year Study Reveals the Surprising Truth About Sitting and Dementia

A 19-year study of more than 20,000 adults linked mentally passive sitting, such as TV watching, with a higher dementia risk.

Mentally active sedentary activities, including reading and office work, were associated with a lower dementia risk.

The results suggest dementia prevention may depend on the kind of sitting, not just the total time spent sedentary.

The study, from Karolinska Institute and Deakin University, was published in the American Journal of Preventive Medicine.
