Traumatic brain injuries are a major cause for concern for our troops returning home from military conflicts abroad. The development of a new eye-tracking device, initiated and funded, in part, by the United States Department of Defense, will soon provide an immediate assessment of traumatic brain injuries. How might this device change the entire evaluation process for these injuries? When will this device be ready for use? Host Dr. Mark Nolan Hill gets the details from Jamshid Ghajar, MD, PhD, president of the Brain Trauma Foundation, the organization working in partnership with the Defense Department to develop this device.
