Body Weight and Dementia Risk

While being overweight is linked to a number of poor health outcomes, being underweight in old age can have a detrimental effect on the brain. In this study, which looked at data from the Gothenburg Birth Cohort Studies, researchers found that seniors with a body mass index under 20 had a greater risk for dementia than participants who maintained a healthy body weight during old age.
