This bill establishes the Veterans TBI Adaptive Care Opportunities Nationwide Act of 2025 , directing the Secretary of Veterans Affairs to create the "TBI Innovation Grant Program." This three-year program will award grants to eligible entities to develop, implement, and evaluate methodologies for prospective randomized control trials focused on neurorehabilitation treatments for chronic mild traumatic brain injury (mTBI) in veterans. The initiative aims to explore novel and integrative treatments, prioritizing patient-centered care and non-pharmacological therapies. Funds from these grants will support activities such as designing and testing new mTBI treatments, conducting clinical studies to measure effectiveness in improving mental health outcomes, reducing suicidality, and mitigating long-term mTBI effects. Grantees are also expected to provide training for clinicians, conduct outreach to veterans and their families, and establish partnerships with community organizations, academic institutions, and VA health care facilities. The Secretary may award up to $5,000,000 per fiscal year to an eligible entity, prioritizing those with demonstrated experience in delivering or researching effective mTBI treatments. The program mandates rigorous oversight, requiring grantees to submit annual reports detailing their activities and measured outcomes, while the Secretary will conduct annual evaluations of the program's efficacy. The grant program must align with existing VA mental health services, specifically the Staff Sergeant Parker Gordon Fox Suicide Prevention Grant Program, to ensure comprehensive support and foster research into integrated mTBI and mental health interventions. Congress will receive annual reports on the program's findings and recommendations for policy and programmatic improvements, with $30,000,000 authorized for appropriations for fiscal years 2026 through 2028.
