I would say that there are some psychiatrists who are willing to perform these, but in my opinion, they're willing to perform these in the absence of evidence. The fact that they're willing to do something that evidence shows they can't should not be reassuring.
I have looked at the evidence of this, and once again, there is no evidence that shows that we can predict irremediability in mental illness. It is vastly different—vastly different—from other medical conditions and neurodegenerative diseases.
