HR-4805-119
Subcommittee Hearings Held
Sponsored by Jennifer Kiggans (R-VA)
What it does
This bill would direct the Secretary of Veterans Affairs to conduct a comprehensive, longitudinal study on the long-term physiological and psychological effects of military aviation on veterans who flew high-performance aircraft. It would also require the VA to establish a centralized Military Aviator Neurohealth Registry to collect anonymized, voluntary health data from participating aviators. The Secretary would be required to submit an interim report to Congress within one year and a final report within three years of enactment.
Who benefits
Current and former military aviators — including fighter, attack, trainer, and tiltrotor aircraft crews — who may have suffered undiagnosed neurological or psychological harm from G-force exposure and other flight stressors. Veterans with conditions such as traumatic brain injury, CTE, ALS, Parkinson's disease, depression, or PTSD who may gain access to better screening and treatment as a result of study findings. Future military aviators whose equipment design and health monitoring protocols may improve based on recommendations. Academic institutions and research centers in aviation medicine and neuroscience that would be consulted and potentially funded. VA healthcare providers who would gain better diagnostic tools.
Who is hurt
Defense contractors and aircraft manufacturers whose equipment (helmets, oxygen systems, flight suits) may face scrutiny or redesign requirements based on study findings. The VA and Department of Defense would bear administrative and research costs, which could compete with other program priorities. Taxpayers would fund the study, though no specific appropriation amount is stated in the bill. Military aviators who choose not to participate in the voluntary registry may still face indirect pressure to enroll.
Supporters argue
Supporters argue that military aviators routinely endure sustained G-forces that can reach 9 times the force of gravity, yet no comprehensive federal study has systematically tracked the long-term neurological consequences of this exposure across a career. They contend that conditions like CTE and sub-concussive trauma — now well-documented in contact sports — are plausibly linked to repeated G-force stress, and that the VA currently lacks the longitudinal data needed to diagnose, treat, or compensate affected veterans. Establishing a neurohealth registry would create the evidence base necessary to improve both veteran care and future aviator safety standards.
Opponents argue
Opponents argue that the bill authorizes a study without specifying any funding mechanism or appropriation, raising questions about whether the VA has the resources to conduct a rigorous longitudinal study on top of its existing obligations. They contend that the voluntary nature of the registry may produce a self-selected, non-representative sample that limits the scientific validity of findings, and that the three-year timeline for a final report may be insufficient for a study examining conditions — like neurodegeneration — that can take decades to manifest. Critics may also argue that existing DoD and VA research programs already address some of these questions, making a new dedicated study duplicative.
