Perhaps her doctor might be able to give her something to help her calm
down?
I hope they can.   I do know how it is, JJ.   My heart goes out to you.

Wellll, the hospice person may have a clue, but having been through
the last stages of AD with my MIL, and gotten literally hundreds of
letters about the same stage from my volunteer work at
allexperts......never heard of "termination agitation" in reference to
AD.

Much more typical of someone actually passing from their AD was my
MIL. Stopped walking and talking about 1.5-2 years before her death,
became totally incontinent, and from there, less and less of
everything. Agitation passed off, she moved less, slept more, and
became totally helpless and vacant, and had to be spoon fed with a lot
of coaxing and patience. Got to the point where she was propped in bed
or propped in the chair, with no attempts to get up (if you put her in
a chair without propping, she'd fall over). Started eating and
drinking less and less despite coaxing, and went into a final 6-8 week
spiral, at the end of which, she finally passed away.

The thing in is, JJ, that if your mother's overall health is poor, and
there is something significant waiting to mercifully carry her off
before the AD reaches its natural conclusion, I could see the hospice
worker's idea being plausible.  However, if her current major health
issue is the AD itself, it could literally be years before she goes.
My MIL was overall quite healthy and robust, so sadly there were no
complicating factors to help her out of the twilight zone, like a
cancer or heart condition. If she hadn't had AD, she would have died
at 9o-something instead of right before her 80th birthday.

This last part was a nightmare, given that the person has vacated
their body, but lives on, and requires very heavy care - its like
having a 120 lb newborn on your hands that needs constant care. Like
other posters, I'd strongly recommend institutional care. The last
stage is a killer for the carer trying to do it alone at home because
the person not only is totally, 100% helpless and dependent, but they
don't know who you are, you can't talk to them, there is no positive
interaction and feedback - you stop getting those moments when you get
a flicker of recognition, a smile that is meant for you, the grasp of
a hand. It just can become a brutal slog, and that is not what your
mother would have wanted for either of you. She needs you in good
shape to look out for her - she doesn't necessarily need YOU to do all
the heavy care. Your job is to love her and make sure she's well
looked after - not do it all yourself.
