> I don't know why this is, but dementia is often a continuum, and the decision making that people make seems to change in early dementia.

More likely it is that theoretical death sometime in the future is something much different then real death sometime soon. Which is much different to actually doing it and following up.

The exact same thing happens in physical danger situations. People are brave and daring and when faced with actual situation, the start making real decision differently.
