2022 Alzheimer’s Disease
Facts and Figures
Special Report
More Than Normal Aging: Understanding
Mild Cognitive Impairment
,About this report
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,
the dementia care workforce, and the use and
costs of health care, long-term care and
hospice. A Special Report examines consumers’
and primary care physicians’ perspectives on
awareness, diagnosis and treatment of mild
cognitive impairment (MCI), including MCI due
to Alzheimer’s disease.
The statistics, facts, figures, interpretations and statements made in this report are
based on currently available data and information as cited in the report, all of which are
subject to revision as new data and information become available.
