In the first example, it's hard to make a case for eligibility just because of the mental illness, because the belief will probably still be driven by the mental illness, or the implications of the mental illness, that they are subjected to. In the second example, they could be eligible if clearly the illness is not contributing to the capacity and they are suffering from a terminal physical illness considered by a board, by a consensus, or by the physicians to be irremediable. The difference is that in mental illness it's hard for us to see if just because of a mental illness the condition could be irremediable.
