President Trump signed S.1071 into law on December 18, 2025. The National Defense Authorization Act for Fiscal Year 2026 was sponsored by Sen. John Cornyn (T), and co-sponsored by Sen. Ted Cruz, and received bipartisan support in Congress. The House passed the measure 312-112 on December 10, with the Senate approving it 77-20 one week later.

Similar to the redesignation of the Department of Defense as the Department of War, the $900 billion defense package appears to focus more on military action than research  As early as May 2025, ESPN reported, “The Trump administration’s 2026 fiscal budget request to Congress eliminates major federal funding for traumatic brain injury (TBI) research and education, potentially undercutting efforts to address head injuries in sports, particularly at the high school and youth levels.” The 2024 funding bill also included decreased funding for brain injury research. 

Whether the bill affects treatment options and research, and to what level, is to be seen.* It appears that some broader funding can be given to any study, even if it goes above the mandated TBI research amount. Additionally, most of the plentiful research I report on seems to be unrelated to the Department of War.

*Only one day prior to the signing of S.1071, Rep. Lori Trahan (MA) introduced H.R.6823 – “To direct the Secretary of Defense to establish a pilot program to facilitate the development of certain traumatic brain injury diagnostics for members of the Armed Forces.” On that day, December 17, 2025, it was referred to the House Committee on Armed Services. Since that time, no further action has been taken.
