An immediate and definite need exists for a portable screening device to provide objective assessment of mild-Traumatic Brain Injury (mTBI) and assist in the discrimination between mTBI and Post Traumatic Stress Disorder (PTSD) diagnosis. This research addresses the development of a portable diagnostic device and a series of non-invasive tests that measure changes in motor and/or sensory cranial nerve function. The device and instructions are intended to fit within a form factor approximately the size of a laptop computer case, and be easily administered by medics in the field. The occurrence of mTBI is under-diagnosed, both by the warfighters and by Army corpsmen. If these injuries could be detected objectively, quickly, and non-invasively, medical personnel would be able to begin early interventions.
