To date, I believe I've worked with three people who have been mefloquine exposed, two of whom had the prodromal reaction. One of them is a more recent one, so I was able to catch that and say what was going on there. The other one was the one who introduced me to the concept of mefloquine toxicity. In that particular case—I think that's sort of my standard—that fellow had been diagnosed some years before I'd ever heard the word.
In my opinion, the diagnosis of PTSD is not inaccurate in his situation, but we'd have to look at that case by case. We may very well have people out there who have been so identified, who are not actually suffering from PTSD. As I say, I think it's complex.
