Abstract
IntroductionWe examined whether educational attainment differentially contributes to cognitive reserve (CR) across race/ethnicity.MethodsA total of 1553 non-Hispanic Whites (Whites), non-Hispanic Blacks (Blacks), and Hispanics in the Washington Heights-Inwood Columbia Aging Project (WHICAP) completed structural magnetic resonance imaging. Mixture growth curve modeling was used to examine whether the effect of brain integrity indicators (hippocampal volume, cortical thickness, and white matter hyperintensity [WMH] volumes) on memory and language trajectories was modified by education across racial/ethnic groups.ResultsHigher educational attainment attenuated the negative impact of WMH burden on memory (β = -0.03; 99% CI: -0.071, -0.002) and language decline (β = -0.024; 99% CI:- 0.044, -0.004), as well as the impact of cortical thinning on level of language performance for Whites, but not for Blacks or Hispanics.DiscussionEducational attainment does not contribute to CR similarly across racial/ethnic groups.
