One thing clinicians will tell you is that the term “irremediable” is foreign to them. It's not even a clinical term. They recognize “incurable”. When you have certain kinds of conditions—not just mental disorders—the conventional understanding of “incurable”—there is no cure—is not available. The lack of consensus around what “incurable” means is not specific to mental disorders. Again, it doesn't work as a justification for singling out mental disorders.
The other thing I would say, in relation to that Globe editorial, is that a group of psychiatrists published a response to it, because it was full of misinformation. I invite the committee to review that response.
