New study finds dementia risk for Americans over 55 is 42%, more than double previous estimates.

A new study in Nature Medicine reveals that the risk of developing dementia after age 55 among Americans is 42%, more than double previous estimates. By 2060, the number of new cases is expected to double to about 1 million annually. The increase is linked to the aging population, with higher risks for women, Black Americans, and those with the APOE4 gene variant. The study emphasizes the need for health policies focused on prevention and health equity to address the growing burden of dementia.
