Technology being developed in Canada to detect brain injuries on battlefield
Canadian military scientists are trying to develop technology to detect possible brain injuries in soldiers exposed to powerful blasts that can leave them with dangerously hidden wounds. The current problem is that there is no way to know whether troops who are exposed to blasts, but bear no visible injuries, have suffered a mild form of brain trauma even if they are a distance from the explosion. Dr. Bob Cheung, a scientist with Defense Research and Development, is looking at several real-time technologies, including ones that measure brain wave activity and cerebral blood flow. He is exchanging information with colleagues in the U.S. and is hoping the portable device they hope to develop will be applied to the civilian population. American researchers recently developed a small device that resembles an oversized iPod and has an electrode strip that can indicate whether a patient's brain functions deviate from normal.
