That's what we say. We say that it's not related. It has not been demonstrated to be related, but it exists. Nevertheless this entity does exist. We cannot wish it away; it does exist. It's been demonstrated very clearly, not just with the Canadians but with many troops. Essentially, among troops deployed by NATO countries, a number of them come back and they're not the same, and there's nothing that shows. It's not physical. It doesn't show up in a blood test. It doesn't show up on an x-ray. It doesn't show up in anything. It is a symptom. They are uncomfortable. They can't sleep. They're bothered. There's a whole array of symptoms.
Some are more clearly defined under this broad umbrella. For example, PTSD, post-traumatic stress disorder, is more easily definable. There are diagnostic criteria that have been established. It's not related to depleted uranium. That has never been demonstrated. There is no test that you can do. There's no blood test; there's no urine test; but there is a treatment. It's not just one treatment. It's not a pill, but it's a combination of different treatments, and overall success can be achieved.
