I got this for my father-in-law who suffers from PTSD after Vietnam, but it was short, so I decided to read it myself as well. This is like a research study report. It is easy to understand, but goes through the basic steps of a research project. Throughout the beginning, he defines and discusses PTSD with stories from soldiers that he worked with. You get a good idea of the symptoms, consequences, and challenges that people suffering with PTSD go through. This is needed as McLay sets the background for his new idea of working the Virtual Reality. He uses VR in small sessions, gradually growing longer to explore dealing with the anxiety that war-like conditions. He states endlessly that this is not a one-size fits all therapy and that it is an extremely difficult process.
Overall, I found it extremely interesting. My father-in-law also enjoyed reading it. He likes to keep up to date with new treatments. He asked the VA if this was something that would be tried any time soon, but they stated that it was not currently something that offered as therapy. So, interesting as it may be, it is still extremely limited.
