Cognitive resilience has emerged as a mechanism that may help explain individual differences in cognitive function associated with aging and/or pathology. It is unknown whether an association exists between family income level and cognitive resilience. We performed a cross-sectional study to estimate the relationship between family income level and high cognitive resilience using the National Health and Nutrition Examination Survey (NHANES) among older adults (age≥60). Logistic regression was used to estimate the association between income level and high cognitive resilience adjusted for other factors. Accounting for differences in education, occupation, and health status, older adults in the highest income category were twice as likely compared to those with very low income to have high cognitive resilience (OR: 1.90, 95% CI: 1.05,3.43). A doseresponse was apparent between income category and high cognitive resilience. The finding that income, above and beyond that of known factors, affects cognitive function is important for future public health strategies that aim to prevent or delay cognitive impairment.
