No, that type of behaviour is later middle stage, not the last stages.
And apart from a few specific and rare types (usually the early onset type),
Az *is not* inherited.

I'm not worrying about the hereditary aspects of it - got my fingers crossed
that they'll have better treatments/a cure before then - and if not, oh
well.... I've got WAY more than enough to deal with at the present time
without expending energy worrying about things I can't control/change. My
partner is somewhat more concerned about it - but he's more than a decade
older than I, so I suppose that's why.

The one thing to remember about even the most unpleasant of behaviours, I
find, is that this too shall pass.... that is the ONLY thing that I find the
least bit positive about all of this - that when confronted with a new
behaviour, I can be quite sure that it will not last ....  of course,
realistically, quite often the ~next thing~ is generally not an improvement
either ....  but I prefer not to focus on that either! And sometimes,
truthfully, the new 'developments' (not the right word, since they all come
from LOSSES, I suppose) .... are sometimes easier to deal with.

Dear Barb,

It isn't a definite inherited thing.   There is an inherited factor, but it
isn't always the way.

There are probably many worse ways to die than alzheimers, but tell me
please, is there some "good" way to die?

Yet we are all going to die at some point.

It is not worthwhile to dwell on it if it destroys the enjoyment of the life
we have now.
