Your Eyes Can Reveal What’s In Your Brain

In March 2026, the University of Colorado Anschutz Medical Campus published the results of a study that reveals high-speed eye-tracking technology can detect lasting neurological damage from mild traumatic brain injuries. More so, it showed that the damage that can be detected may be completely invisible to MRI scans, CT imaging, and routine clinical exams. This matters enormously. Current standard concussion assessments are largely subjective and can result in patients being told they’ve recovered when their brains are still struggling.

At the CU’s Marcus Institute for Brain Health, researchers tested 78 military veterans and measured subtle disruptions in eye movement that expose hidden neural damage. The findings were sobering: deficits persisted 10 to 15 years after the original injury. As Dr. Jeffrey Hebert, who led the study, noted, “Even when someone feels recovered, their brain may still be working differently behind the scenes.” Funded by the Department of Defense, this technology offers something conventional medicine currently cannot – objective, documented proof of brain trauma.

Pentagon’s New Coding Rules Aim to Protect Warfighters

On January 23, 2026, the Department of Defense’s Traumatic Brain Injury Center of Excellence published updated ICD-10-CM coding guidance specifically for warfighter brain injuries. ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the standardized system doctors use to classify and record diagnoses. Without precise codes, injuries go miscounted and undertreated.

The new guidance is particularly critical now, as modern warfare inflicts unique brain hazards. Low-level blast overpressure from repeated weapons firing, extreme G-forces on pilots, and unexplained neurological incidents now have dedicated diagnostic codes, enabling better surveillance and resource allocation.

Just days earlier, on January 20, the Center released a research review revealing that mild TBI raises PTSD risk two- to threefold, findings that will shape military treatment protocols. Meanwhile, the Army’s baseline cognitive screening program, launched in August 2024, aims to assess every troop’s brain health proactively.
