Socioeconomic status is known to affect brain health, and white matter hyperintensities (WMH) in particular, through stress, inflammatory, and metabolic pathways. WMH reflect underlying small vessel ischemic damage and cardiovascular disease and are an important predictor for cognitive impairment and Alzheimer's disease and related disorders. Interestingly, prior research indicates that the association between socioeconomic status and WMH differs across race and ethnicity. This study examines how a unique measure of socioeconomic status - financial worry - is associated with WMH and whether these associations differ across race and ethnicity in a sample of older non-Hispanic Black, Hispanic, and non-Hispanic White adults in northern Manhattan. Theoretical background, findings, and implications of the results will be discussed.
