Myricetin and isorhamnetin were not associated with global cognition.Discussion Results suggest that dietary intakes of total flavonols and several flavonol constituents may be associated with slower decline in global cognition and multiple cognitive abilities with older age.MAP=Memory and Aging Project; FFQ=food frequency questionnaire; RADC=Rush Alzheimer's Disease Center ER -
