This bill aims to reauthorize and significantly improve federal programs dedicated to the prevention, detection, and treatment of traumatic brain injuries (TBIs) . It specifically amends the Bill Pascrell, Jr., National Program for Traumatic Brain Injury Surveillance and Registries to expand its scope. The program will now focus on the incidence and prevalence of TBIs, including associated injuries and fatalities, and related risk factors. Key enhancements include identifying populations at higher risk for TBIs, such as those with occupational or circumstantial factors, and collecting detailed data on causes and risk factors. The Secretary of Health and Human Services, acting through the CDC, must make aggregated TBI and concussion information publicly available, including tailored prevention strategies for high-risk groups. The legislation also modifies State Grant Programs for TBI, allowing for the inclusion of American Indian consortiums and introducing a maintenance of effort requirement for non-Federal expenditures. It permits the Secretary to waive up to 50 percent of matching funds under certain conditions and updates the definition of traumatic brain injury. Additionally, state grants for protection and advocacy services for TBI are reauthorized. Furthermore, the bill mandates a report to Congress within two years on high-risk TBI populations, current CDC activities, and outreach challenges. It also requires a comprehensive study on long-term symptoms or conditions related to TBI . This study will examine incidence, prevalence, correlations with other conditions like dementia and mental health, existing services, and research gaps across the lifespan. These programs, including the surveillance program and state grants, are reauthorized for appropriations for fiscal years 2026 through 2030 , ensuring continued federal support for TBI initiatives.
