Alzheimer Burden

JAMA. 2018;320(18):1851. doi:10.1001/jama.2018.16787

The percentage of US adults with Alzheimer disease and related dementias is projected to grow from 1.6% in 2014 to 3.3% in 2060, according to a study by the CDC in the journal Alzheimer & Dementia.

The study authors estimated the future prevalence of Alzheimer and related conditions using 2014 data on fee-for-service Medicare beneficiaries and population growth estimates from the US Census Bureau. According to the study, 2 factors are likely to contribute to growing prevalence of Alzheimer disease and other dementias. One is the projected doubling of US individuals aged 65 years or older from 46.5 million in 2014 to 83.7 million by 2060. Another is faster projected growth in minority elder populations who are disproportionately affected by dementia.
