Victims of violence in the United States are just as likely to experience post-traumatic stress disorder as veterans of war. PTSD rates are particularly high in inner-city neighborhoods with high levels of violent crime. Even gang members, assumed to be toughened by repeated exposure to violence, experience it, since PTSD often has a cumulative effect. Most hospitals aren’t screening or treating patients for PTSD because of the additional expense. Medicaid doesn’t pay hospitals to deal with it (ProPublica, February 3).
