Cognitive Function and Salivary DHEA Levels in Physically Active Elderly African American Women.

Serum and plasma dehydroepiandrosterone sulfate (DHEAS) concentration has been associated with several health parameters associated with aging including cognitive function, bone mineral density, and muscular strength.
