Associations Between Brain Microstructure, Cognition and Socioeconomic Factors in a Diverse Cohort : the LASI‐DAD Study

These findings support the role of neurite density, as measured by FICVF, in predicting cognitive outcomes in community-based populations. Interestingly, a stronger FICVF-cognition relationship was observed among individuals with disadvantaged socioeconomic backgrounds. Specifically, lower risks of MCI associated with increased FICVF were seen in those who are illiterate, literate with reading errors, have lower education, are unemployed, or reside in urban areas, compared to their counterparts.
