Dementia only causes about 41% of cognitive decline: new study identifies other predictors

Cognitive decline naturally occurs as we age, with a common belief that dementia is the cause in most cases.

Recently, researchers at the Ohio State University say there are more factors causing cognitive decline than we once thought.

Socioeconomic factors, physical health measures, and behaviors, including exercise and smoking, accounted for 38% of the variation between participants in their level of cognitive function at age 54, researchers reported.

This study is focused on identifying predictors of cognitive decline.
