(Medical Xpress)—Concussions can occur in sports and in combat, but health experts do not know precisely which jolts, collisions and awkward head movements during these activities pose the greatest risks to the brain. To find out, Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. This approach could lead to new medical treatment options and some sports rule changes to reduce brain trauma among players. http://medicalxpress.com/news/2013-03-athletes-soldiers-brain-concussions.html Neuroscience Tue, 05 Mar 2013 18:01:11 EST news281728854 Visual symptoms and abnormalities occur at high rates in people with traumatic brain injury (TBI)—including Iraq and Afghanistan War veterans with blast-related TBI, reports a study, "Abnormal Fixation in Individuals with AMD when Viewing an Image of a Face", in the February issue of Optometry and Vision Science, official journal of the American Academy of Optometry. http://medicalxpress.com/news/2013-02-combat-vets-high-vision-problems.html Neuroscience Mon, 04 Feb 2013 11:50:01 EST news279200228 A study done by investigators at the Boston University Center for the Study of Traumatic Encephalopathy (CSTE) and the Veterans Affairs Boston Healthcare System, in collaboration with the Sports Legacy Institute (SLI), describes 68 cases of chronic traumatic encephalopathy (CTE) among deceased athletes and military veterans whose brain and spinal cords were donated to the VA CSTE Brain Bank. Of the 68 cases, 34 were former professional football players, nine had played only college football, and six had played only high school football. The results, which will be published in the December issue of the scientific journal, Brain, represent the largest case series of CTE published to date, doubling the number of published CTE cases internationally. http://medicalxpress.com/news/2012-12-cte-cases-veterans-high-school.html Diseases, Conditions, Syndromes Mon, 03 Dec 2012 11:45:38 EST news273757467 Barclay Morrison, an associate professor of biomedical engineering, compares the brain's physical response to traumatic brain injury to, of all things, a gelatin dessert. http://medicalxpress.com/news/2012-10-biomechanics-traumatic-brain-injury-treatments.html Medical research Fri, 19 Oct 2012 07:11:26 EST news269849476 In recent years it has become clear that athletes who experience repeated impacts to the head may be at risk of potentially serious neurological and psychiatric problems. But a study of sports programs at three major universities, published in the October 2 Journal of Neurosurgery, finds that the way the injury commonly called concussion is usually diagnosed – largely based on athletes' subjective symptoms – varies greatly and may not be the best way to determine who is at risk for future problems. In addition, the way the term concussion is used in sports injuries may differ from how it is used in other medical contexts, potentially hindering communication about the factors most relevant to patient outcomes. http://medicalxpress.com/news/2012-10-criteria-sports-injuries-inconsistent.html Neuroscience Wed, 10 Oct 2012 13:13:25 EST news269093595 (Medical Xpress)—The gridiron is back in action. From little leagues to professional teams, football frenzy has begun, and with it, concerns about concussions. But it's not just jarring tackles that can lead to concussions in kids. According to Dr. Ryan Coates, a pediatric neurologist at Loyola University Health System, there are many ways kids are exposed to concussion risks. http://medicalxpress.com/news/2012-09-concussions-kids-athletes.html Health Thu, 06 Sep 2012 09:10:52 EST news266141444 UT Dallas researchers recently demonstrated how nerve stimulation paired with specific experiences, such as movements or sounds, can reorganize the brain.

Since developmental dyslexia responds to early intervention, diagnosing children at risk before or during kindergarten could head off difficulties and frustration in school, the researchers say.
