A Comparison of Dementia-free Life Expectancy Estimates Across Competing Algorithmic Classifications: New Knowledge and Considerations from the Health and Retirement Study

Therefore, more work is needed 1) to understand for whom and which models are most accurately identifying dementia and 2) to place these models relative to gold-standard adjudicated dementia assessments.
