In 1994—I'm sorry, in 2004—that was my grant application—at that time, we had devices that would allow us to go into the field and study them before they went into combat, and to see them afterwards, and to look for precisely that.
Now I'm looking at them months or years later, and they're full of compounds and on every known medication that someone can throw at them. I don't think that's the way. I think we've got to teach early detection to physicians in the military. We have to go through a screening system and we've got to do something for them right away.
There is a lot of education that is involved in this. I think that before we venture into the practicalities of the kind of research that you have been hearing about, this is what we've got to do. We've got to know the numbers. We've got to know who these people are. Until we can properly identify them, we're cursed because this is going to go on for decades to come, and we don't know how many will survive.
I'm not just talking about the military people themselves; I'm talking about their families and their spouses. As my friends in England have shown, those with PTSD who come back from Iraq and Afghanistan show more dangerous behaviour, as identified by the police in England.
