Getting to the bottom of PTSD and aggression

Not all soldiers returning from the wars in Afghanistan and Iraq develop post-traumatic stress disorder (PTSD) and not all people with PTSD have problems with anger and aggression but those that do can end up in trouble and hurting those around them. Researchers from the University of North Carolina at Chapel Hill studied 676 military veterans in an attempt to find out what made certain people with PTSD become angry and aggressive. They found that those veterans who had witnessed family violence before joining the military, who had fired a weapon during deployment, had been deployed for more than a year and who were experiencing current hyperarousal symptoms - sleep problems, being 'on edge,' jumpiness, irritability and difficulty concentrating - were more likely to have problems managing their temper.
