2022 Alzheimer’s Disease Facts and Figures 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, long-term care and hospice. The Special Report examines what we have learned about the diagnosis of Alzheimer’s disease through research, and how we could identify and count the number of people with the disease in the future.
