This study estimates the prevalence and number of people living with Alzheimer's disease (AD) dementia in the US. The results show higher prevalence in the east and southeastern regions, with Maryland, New York, and Mississippi having the highest rates. California, Florida, and Texas have the highest number of AD patients. The state- and county-specific estimates can help develop region-specific strategies for care.
INTRODUCTIONThis study estimates the prevalence and number of people living with Alzheimer's disease (AD) dementia in 50 US states and 3142 counties. METHODSWe used cognitive data from the Chicago Health and Aging Project, a population-based study, and combined it with the National Center for Health Statistics 2020 bridged-race population estimates to determine the prevalence of AD in adults & GE;65 years. RESULTSA higher prevalence of AD was estimated in the east and southeastern regions of the United States, with the highest in Maryland (12.9%), New York (12.7%), and Mississippi (12.5%). US states with the highest number of people with AD were California, Florida, and Texas. Among larger counties, those with the highest prevalence of AD were Miami-Dade County in Florida, Baltimore city in Maryland, and Bronx County in New York. DISCUSSIONThe state- and county-specific estimates could help public health officials develop region-specific strategies for caring for people with AD.
