CDC Alzheimer's Disease and Healthy Aging Data: National and State-Level ADRD Indicators
The CDC Alzheimer's Disease and Healthy Aging Data dataset provides national and state-level indicators including caregiving, subjective cognitive decline, screenings and vaccinations, and mental health among older adults. Maintained by the CDC, the dataset gives researchers a population-level view of Alzheimer's disease and related dementias (ADRD) risk factors and care patterns across the United States. Researchers and program evaluators can use these indicators to identify priority areas and track progress over time.
What the Dataset Contains
The dataset contains:
- Four indicator domains: caregiving, subjective cognitive decline, screenings and vaccinations, and mental health
- National and state-level coverage
- Originally published July 27, 2020, and last updated September 8, 2025
What Researchers Can Do With This Dataset
Researchers can use this data set to compare national and state-level rates of cognitive decline, caregiving burden, and mental health outcomes among older adults, and to evaluate how these rates shift as public health interventions are introduced. The indicators support prioritization of ADRD surveillance efforts and evaluation of state and regional health programs targeting cognitive health.
How to Access The Dataset
The CDC Alzheimer's Disease and Healthy Aging dataset is discoverable through the AD Discovery Portal and accessible within individually permissioned AD Workbench workspaces at no cost to qualified researchers. AD Workbench provides free compute, virtual machines, and multimodal analysis tools and allows researchers to bring their own code, models, and approved external datasets into their workspace.
