I would answer that the same concern exists in physical medicine. This might be the perception among doctors treating various neurological conditions and different disorders. I don't want to pass any judgment on their level of paternalism.
From my personal clinical experience, I can tell you about situations where people had appropriate and sustained access to an array of incredible treatments and, unfortunately, they continued to perceive their suffering as intolerable.
I think we should recognize their autonomy and their capacity to judge their situation. Of course, I am not talking about cases of suicidality. However, in general, people who are suffering are capable of assessing it and deciding what they want for their lives. We have to listen to them.
This is not unique to mental illness; it is the same in physical medicine.
