Description
Jay Lusk and co-authors track how dementia gets labeled in American billing data in a 2025 study. Lab-grade studies define dementia subtypes precisely but cover narrow groups, while real-world diagnosis lives in insurance claims. The team read every Medicare claim from 2014 to 2021 and sorted new dementia cases by coded subtype.
More than 5.7 million people received a first dementia diagnosis in the window. Results were split by age, sex, ethnic group, and neighborhood deprivation score to expose uneven labeling. Vascular dementia's share of codes grew between 2015 and 2021, one early signal of shifting practice. The study argues that who gets which label depends on social context as well as biology, a caution for planning care and research alike.
