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.

This bill establishes a pilot program (the Warfighter Traumatic Brain Injury Diagnostics Project) to support the development of new diagnostic tools for traumatic brain injury (TBI) among active-duty military members, particularly during deployments and combat. The program directs the Secretary of Defense to assess diagnostic technologies' ability to distinguish TBI severity, integrate with existing medical tools, and improve military readiness, while awarding grants to eligible research entities with priority for those with proven experience in TBI diagnostics. It authorizes $5 million annually (2026-2029) for research, development, and testing, requiring a congressional report on results and recommendations by 2029. The initiative directly affects service members with potential TBI, military medical providers, and research organizations developing diagnostic technologies for military use.
