Defense Funding for TBI Research Sees Significant Decline

What happened

Funding for the Defense Department's medical research into traumatic brain injuries (TBIs) has decreased significantly over the past three fiscal years. Spending dropped from $175 million in fiscal 2024 to $40.5 million in fiscal 2026. The House's proposed Defense spending bill for fiscal 2027 does not include an increase for this research.

Why it matters

Traumatic brain injuries have been described as the signature wound of current wars. The reduction in funding impacts research into TBI detection, treatment, and associated psychological health issues like PTSD. Shannon Connell, CEO of the Invisible Wounds Foundation, stated that the funding cut "essentially shuts down the pipeline of research needed to understand the underlying cause of these injuries."

Key context

TBIs are among the afflictions supported by the Congressionally Directed Medical Research Programs (CDMRP). Research into conditions like TBIs, which disproportionately affect U.S. military personnel, has seen some of the largest cutbacks within the CDMRP. In fiscal 2024, the overall CDMRP received $1.51 billion. This figure dropped to $650 million in fiscal 2025 and $1.27 billion in the current fiscal year. The House's draft fiscal 2027 Defense spending bill proposes $916.5 million for the CDMRP. Rep. Mike Levin noted that the House's version of the fiscal 2027 Defense spending bill would cut research funding for numerous diseases and disorders, including reductions for autism, melanoma, and vision research, and elimination of funding for epilepsy, hearing restoration, and military burn research.

What to watch next

It remains uncertain what additions the Senate may propose to the fiscal 2027 Defense spending bill. Virginia Tech officials have stated the university is well-positioned to receive more Department of Defense research funding, but the specific opportunities are not yet identified.
