Brief Summary

Traumatic brain injury (TBI) is one of the most frequent injuries affecting service members. Unfortunately, current neurocognitive assessment tools are unable to reliably detect mild TBI more than a few days post- injury. Therefore, development of advanced systems for assessment and diagnosis of TBI are a top priority within Department of Defense. This project aims to evaluate a combined electroencephalography (EEG) and eye tracking system capable of assessing compromised cognitive function stemming from TBI, with the goal of enhancing operational readiness and aiding in diagnosis, improving health care and rehabilitation for affected military personnel.
