Why the irremediability requirement is not sufficient to deny psychiatric euthanasia for patients with treatment-resistant depression.

Treatment-resistant depression (TRD) holds centrality in many debates regarding psychiatric euthanasia. Among the strongest reasons cited by opponents of psychiatric euthanasia is the uncertainty behind the irremediability of psychiatric illnesses. According to this argument, conditions that cannot be considered irremediable imply that there are possible remedies that remain for the condition. If there are possible remedies that remain for the condition, then patients with that condition cannot be considered for access to euthanasia. I call this the irremediability requirement (IR). I argue that patients with TRD can, indeed, meet the operationalisation of irremediability in the IR. This is because the irremediability it asks for is not some global or absolute irremediability, but rather a present irremediability based on the current state of medical science. I show this by considering irremediability relating to (1) possible future treatments and (2) not trying presently available alternative treatments. I extend Schuklenk nd van de Vathorst's argument from parity to terminal malignancies, to show that (1) is an unreasonable expectation for all cases of euthanasia. Taking (2) as a more serious opponent to psychiatric euthanasia, I show how the IR, based on how it is presently operationalised, can be realistically applied to cases of TRD. I do this by further developing Tully's argument on broad-sense treatment resistance with the robust empirical data from the STAR*D trials. If my argument from Tully's is valid, then we have reasons to, again, seek parity between the operationalisations of irremediability in terminal malignancies and TRD.
