The US government’s top psychiatric researcher estimates the number of suicides among veterans of the wars in Iraq and Afghanistan may exceed the combat death toll of the wars because of inadequate mental healthcare. Thomas Insel, director of the National Institute of Mental Health in Bethesda, Maryland, said community mental health centers have failed in providing adequate care to veterans. A recent study by the RAND Corporation determined that 20 percent of returning US soldiers have post-traumatic stress disorder or depression, and only half of them receive treatment. The House Veterans Affairs Committee is holding a hearing this morning on the issue of veteran suicides. Steve Rathbun from the University of Georgia will be testifying. According to his research, as many as 120 veterans are committing suicide every week.
