Sources: Stroke — CDC, age-adjusted stroke mortality among adults 35+, 2021–2023, by sex. TBI — CDC TBI-related hospitalization rates (2020). Alzheimer's — Alzheimer's Association 2024 Facts & Figures, prevalence in adults 65+. Cognitive decline — CDC BRFSS Healthy Aging Data, self-reported worsening memory loss (subjective cognitive decline) in adults 45+, latest available year per state; an early indicator, not a dementia diagnosis. Research $ — NIH RePORTER, NINDS awards FY2025, per-capita using Census 2024 population estimates. Burden score is a weighted composite.
