Chicago psychiatrist K Luan Phan, who did not treat Van Dorn but is a PTSD researcher at the University of Illinois-Chicago, said: "Some medications are used for depression, some are for anxiety and there are very few medications that are particularly good for PTSD or are useful for PTSD."
On April 8, Staff Sgt. Cole Van Dorn, 29, was found dead at his home. He was being treated for PTSD. (WLS)
