2020 Alzheimer's Disease Facts and Figures

The Alzheimer's Association's 2020 Alzheimer's Disease Facts and Figures report (PDF) is a statistical resource for U.S. data related to Alzheimer's disease, the most common cause of dementia. Background and context for interpretation of the data are contained in the Overview. Additional sections address prevalence, mortality and morbidity, caregiving and use and costs of health care and services.

An accompanying special report, Primary Care Physicians on the Front Lines of Diagnosing and Providing Alzheimer's and Dementia Care: Half Say Medical Profession Not Prepared to Meet Expected Increase in Demands, examines primary care physicians' experiences, exposure, training and attitudes in providing dementia care and steps that can be taken to ensure their future readiness for a growing number of Americans living with Alzheimer's and other dementias. The special report begins on page 65 of the 2020 Alzheimer's Disease Facts and Figures report (PDF).
