Thank you very much for that question.
PTSD is of course considered a mental condition or a mental illness, and it has a certain number of symptoms that we look for. Then there are a number of other things. We have to rule out certain things. We look at the person's level of functioning and how long he's had the symptoms. But there are very well-prescribed symptoms. Whether somebody has developed PTSD because they were sexually assaulted or abused as a child or has been in a combat zone, although the details of the events are different, the symptoms they suffer from essentially are the same.
That's I think what I was alluding to in terms of, yes, there can be people we diagnose with PTSD who, again, perhaps were abused as children, entered the military, and spent many years in the military, and who then for some reason come forward. They can have PTSD; it may not be related to combat. But certainly, most of the PTSD we treat is related to, yes, being in the war zone.
