I think that's an interesting point you raise. I think if you look at the body's response to trauma.... Trauma does not just have to be a physical trauma or an emotional trauma. There could be traumas of many types, and often it could be a combination of the two.
The conference I said I'm going to, which is hosted by One Mind, will be addressing two of those things. It will look at physical brain injury as well as post-traumatic stress disorder. The reason they're bringing these together is that in the realm of sports, for example, there's a lot of concern about people who are exposed to physical trauma to the head that gives rise to something else.
It all boils down to how the organ of the brain responds to different kinds of trauma and what makes one person respond differently from another. The more we understand about that, the more fundamental solutions we'll be able to find.
