Could we not go back upstream, for example, to when the decision is made, the point of the meeting between the care team and the person with Alzheimer? When the person needs to express their wishes, could that stage or possibility not be described, with full knowledge of the facts, and ask the person clearly what they would want to be done, if it is believed that they are in a state of happy dementia?
Is a third party not, in a way, the key in a situation like that? If the third party does not tell the care team to start the assessment, nothing gets done. I imagine the third party is not an evil person. Some people imagine that as soon as that door is opened, everyone in the health care system is going to become evil. If it is a third party, they are necessarily benevolent. So as long as the third party says nothing, the assessment doesn't start.
