The Army says nearly every soldier has now completed a new cognitive baseline test intended to help detect and track brain injuries related to blast overpressure. Officials report 97% participation in the Neurocognitive Assessment Tool, a computer-administered exam that measures functions such as memory and reaction time.
What the test does and why it matters
- All soldiers across the active-duty Army, Army National Guard and Army Reserve must take the NCAT. Regular testing cycle: every three years.
- Soldiers in career fields that routinely encounter heavy blasts—field artillery, combat engineers, explosive ordnance disposal (EOD) technicians and similar specialties—must take the assessment annually and at specific points: upon entering service, before deployment, and after injury or suspected concussion.
Department made the cognitive baseline assessment mandatory in 2024 to improve monitoring and recovery support for traumatic brain injury. The Army describes the NCAT as part of a larger effort to treat blast overpressure and low-level blast exposure as occupational safety and health hazards. The Army plans to publish a service-wide directive that will define elements like exposure tracking, risk mitigation measures, injury reporting protocols, training requirements and cognitive monitoring procedures.
The Army has attempted cognitive testing before and has sometimes failed to maintain follow-through. The report cites an earlier case where an artillery unit received pre-deployment neurological tests but did not receive required post-deployment assessments despite repeated blast exposures during deployment. The new NCAT program aims to close that gap by standardizing baselines and follow-up testing across the force.
Jordan Gillis, the assistant secretary of the Army for installations, energy and environment and a field artillery officer with combat experience, said establishing cognitive baselines will help monitor soldiers' brain health and assist medical providers with treatment. Gillis noted his own exposure to IEDs and related blast incidents during deployment.
What this means for soldiers and medical care
Clinicians will have a standardized cognitive reference point to detect declines or changes after blast exposure or concussion. For soldiers in high-exposure roles, annual testing increases the chance of identifying incremental changes early. The broader overpressure program promises coordinated exposure records and risk controls alongside cognitive monitoring, which could change how the Army tracks and responds to low-level and repeated blast injuries.
The Army intends to publish a directive outlining procedures and responsibilities, but implementation details such as data access, follow-up care timelines, and how exposure tracking will integrate with existing health records were not specified in the report.
