Implication

Cross-sectional study reveals significant state-level variation in dementia prevalence among Medicare beneficiaries, indicating substantial underdiagnosis and unequal healthcare planning needs.

Key Points

To describe state-level variation in dementia prevalence across the United States and compare observed diagnosed rates against expected prevalence benchmarks.
Analyzed a 20% sample of Medicare beneficiaries in 2008 (N = 4.8 million).
Calculated crude dementia prevalence and age- and sex-standardized rates to the US population by state, comparing findings to expected rates from the World Alzheimer Report 2009.
The overall adjusted dementia prevalence was 8.24%, ranging from 5.96% to 9.55% across states.
Diagnosed prevalence fell below expected levels in most states, revealing an estimated excess of more than 100,000 undiagnosed dementia cases in the Medicare population.
