Estimating prevalence of dementia, mild cognitive impairment in US

JAMA Network

About The Study: Using a comprehensive neuropsychological test battery, researchers found in this nationally representative cross-sectional study of nearly 3,500 individuals age 65 and older that 10% were classified as having dementia and 22% as having mild cognitive impairment (MCI). The results indicated a disproportionate burden of dementia among older Black adults, of MCI among older Hispanic adults, and of both among people with lower educational attainment.
