As far as the psychological approaches goes, most methods treat it like depression or anxiety. Even the medications used are also known to be effective for depression and anxiety, not the actual affliction itself. For example, if a person is having a hard time keeping up with day to day needs because of PTSD, the only options would be to put them in a cognitive-therapy class or put them on Paxil and Zoloft.
My answer to this would be to fund scientific research on PTSD. There needs to be a medical approach to this problem.
