The aging of the US population is expected to lead to a large increase in the number of adults with dementia, but some recent studies in the US and other high-income countries suggest that the age-specific risk of dementia may have declined over the last 25 years. Clarifying current and future population trends in dementia prevalence and risk has important implications for patients, families, and government programs. To compare the prevalence of dementia in the United States in 2000 and 2012. We used data from the Health and Retirement Study (HRS), a nationally representative population-based longitudinal survey of US adults. Population-based prospective cohort of US adults. Individuals aged 65 or older from the 2000 (N = 10,546) and 2012 (N = 10,511) waves of the HRS. Dementia was identified in each year using HRS cognitive measures and validated methods for classifying self-respondents, as well as those represented by a proxy. Logistic regression was used to identify socioeconomic and health variables associated with change in dementia prevalence between 2000 and 2012. Dementia prevalence among those aged 65 or older decreased from 11.6% in 2000 to 8.8% (8.6% with age- and sex-standardization) in 2012 (P < 0.001). More years of education was associated with a lower risk for dementia, and average years of education increased significantly (from 11.8 to 12.7 years; P < 0.001) between 2000 and 2012. The decline in dementia prevalence occurred even though there was a significant age- and sex-adjusted increase between years in the cardiovascular risk profile (e.g., prevalence of hypertension, diabetes, and obesity) among older US adults. The prevalence of dementia in the United States declined significantly between 2000 and 2012. An increase in educational attainment was associated with some of the decline in dementia prevalence, but the full set of social, behavioral, and medical factors contributing to the decline is still uncertain. Continued monitoring of trends in dementia incidence and prevalence will be important for better gauging the full future societal impact of dementia as the number of older adults increases in the decades ahead.
