The physical size of certain regions of a person's brain may be an indicator of risk for developing Alzheimer's disease.

Over a three-year period, researchers conducted brain scans and tests of 159 patients with an average age of 76 who did not have dementia.

Fifteen percent of participants who had the thinnest cerebral cortex also performed the poorest on cognitive testing over the course of the study, indicating a possible correlation between cortex thickness and risk of Alzheimer's

The findings are in the American Academy of Neurology's Medical Journal.
