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.
