Neighborhood disadvantage linked to older-looking brains and more white-matter injury on MRI

What the research found
Study (clinical imaging epidemiology). Willbrand, John-Paul J. Yu and colleagues report in Radiology (doi 10.1148/radiol.260693) on 2,826 consecutive clinical brain MRIs (1,094 men, 1,732 women; ages 18–96) at University of Wisconsin sites, January–June 2024, excluding exams with imaging evidence of disease. Higher Area Deprivation Index (17 census indicators of income, education, employment, and housing) tracked a larger brain-age gap, lower total brain volume, and higher white-matter hyperintensity volume after age and sex adjustment. White-matter hyperintensities are described as footprints of cardiovascular damage and are linked in other work to memory loss and dementia risk. Zip-code disadvantage is not a diagnosis of cognitive impairment. Educational brain-health notes, not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
