Expands the VA Precision Medicine initiative to add repetitive low-level blast exposure, dementia, and other brain and mental health conditions to the program’s research and clinical activities. It requires the Department of Veterans Affairs to partner with the Department of Defense for data sharing, to conduct targeted research and implementation studies, to use outside expert assistance and the National Academies for biomarker validation and reports, and to carry out related assessments and quality‑improvement studies.

Authorizes $5,000,000 per year for fiscal years 2025–2034 to support the expanded initiative and its studies, reporting, and contracts; establishes new requirements for data sharing, study design, periodic reporting, and use of outside expertise to validate biomarkers and improve care for affected veterans and service members.
