Data are provided as Means ± Standard Deviations and [Ranges]. aData were from non-Hispanic individuals. bThe control genotypes used in the preparation of this article were obtained from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database (adni.loni.usc.edu). bBNT scores for the SuperAging group were based on n = 55. *Indicates significant differences between the groups. RAVLT: 15-item list learning test of episodic memory with possible scores ranging from 0 to 15. Category fluency: Semantic fluency task in which individuals say as many items from a given category (i.e., animals) as they can in 1 min. BNT: measure of object naming with possible scores ranging from 0 to 30. Trail Making Test B: timed test that assesses executive attention. Test discontinued at 300 s if not completed. MMSE: brief measurement of cognitive functioning with possible scores ranging from 0 to 30.
