James Giordano, Ph.D., is the Director of the Potomac Institute for Policy Studies' Center for Neurotechnology Studies. Dr. Giordano says with all the attention currently focused on the issue of traumatic brain injury (TBI), both among returning veterans and in the arena of sports, it's a good time to take a closer look at who's at risk for TBI, how we can lessen that risk, and how to provide better treatment to those who have experienced TBI. Dr. Giordano says in many cases, signs of TBI can be subtle, and may not emerge for weeks or months following the injury. In addition, we're learning more about causes of TBI - which can occur even in cases where the patient has not suffered a blow directly to the head. The good news, says Dr. Giordano, is that in recent years we've learned that the brain is not a static organ, and that it retains some ability to remodel and repair itself in our adult years. Dr. Giordano says the challenge is to find treatments that are "technically right and ethically good" for patients who may face a difficult period of rehabilitation.
