Mullen plans to ask his staff whether limiting the number of concussions servicemembers can receive while deployed can reduce the number of troops whose resulting injuries prevent them from returning to duty.
Research from the Defense and Veterans Brain Injury Center (DVBIC), http://www.dvbic.org/, indicates as many as 10 to 20 percent of U.S. troops who had combat exposure may have sustained a concussion during the time they were deployed in Iraq and Afghanistan.
During a roundtable discussion at the Pentagon yesterday as part of "Brain Injury Awareness Month," Army Brig. Gen. (Dr.) Loree K. Sutton, director of the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury, said more than 90 percent of servicemembers with TBI have concussions and recover quickly.
