Another way of saying what I've said before is that what's peculiar about mental disorders is that the staging models we have do not correlate with prognosis. When we talk about something incurable or irreversible, what we know is that someone can rate very high on that staging model, and that in no way correlates with long-term prognosis. That is another way to speak to the prognosis question.
Of course, it's not just a matter of prognosis and uncertainty, as I've said before. It's a matter of having adequate standards for what we call an incurable mental disorder. That is a whole different kind of issue we have in mental disorders that we do not have in physical disorders.
We do know, for example, what the standards for end-stage diabetes are. We may not know if someone.... For sure, there might be uncertainty about the prognosis, but we do have those standards about what we define as end-stage diabetes. We do not have that for mental disorders.
