A recent study of 157 active-duty soldiers and four civilian contractors has revealed that people who\u2019ve suffered multiple concussions throughout their lifetime are more likely to contemplate suicide than those who\u2019ve never suffered a concussion, according to Pacific Standard<\/em> magazine.<\/p>\n The University of Utah National Center for Veterans\u2019 Studies undertook the research because few others had investigated the link between traumatic brain injury<\/a> and suicide, traumatic brain injury is one of the most common injuries sustained in Iraq and Afghanistan, and \u201c[s]uicide is currently the second leading cause of death among military members,\u201d the magazine reported.<\/p>\n In fact, 303 active-duty soldiers killed themselves in 2011 and another 349 killed themselves in 2012. This prompted 53 Congress members to pen a March 4, 2013, letter to the Secretary of Defense and the Secretary of Veterans Affairs, stating, in part, that the number of suicides has reached \u201cunacceptably high levels.\u201d<\/p>\n
