What was done
The Alzheimer's Association compiled public health data to report on the incidence, prevalence, mortality, care utilization, economic costs, and caregiver impact of Alzheimer's disease in the United States. The report also evaluated healthcare workforce demands, specifically focusing on the preparedness of primary care physicians in the context of specialist shortages.
What was found
An estimated 5.8 million Americans aged 65 and older had Alzheimer's dementia in 2020, with projections reaching 13.8 million by mid-century. In 2018, 122,019 deaths were officially attributed to Alzheimer's, making it the sixth leading cause of death overall in the US and the fifth leading cause among older adults; reported deaths increased 146.2% between 2000 and 2018. In 2019, over 16 million unpaid caregivers provided an estimated 18.6 billion hours of care valued at nearly $244 billion. Total payments for healthcare, long-term care, and hospice in 2020 were estimated at $305 billion, with per-person Medicare payments more than 3 times higher and Medicaid payments more than 23 times higher for beneficiaries with dementia compared to those without.
Why it matters
This report establishes the substantial epidemiological, financial, and caregiver burden of Alzheimer's disease in the United States. It highlights an impending public health crisis driven by an aging population alongside a shortage of dementia specialists, placing increasing strain on primary care.
Limits
The findings represent synthesized national surveillance models and projections rather than a single controlled empirical study. The abstract does not report specific primary dataset sample sizes or confidence intervals, relies on death certificate reporting which can be subject to misclassification, and is restricted to US data.
