93 year old mom, end of days and hospice evaluation. Any insight?

My 93 year old mom lives with us and uses a walker to move from room to room most of the time, sometimes she forgets. She was diagnosed with Alzheimer's four months ago and has A-fib. She had a TIA 18 months ago and is on a pureed diet due to esophagus issues. She takes meds for the pain and for anxiety. She also has macular degeneration in both eyes and can no longer read. Her paranoia and irritability are increasing. She has not been able to handle her affairs for about two years. We have palliative care once a week for her that helps her in the shower. Her fatigue level has increased to the point that she sleeps 18+ hours a day on and off. She fell five weeks ago and fractured one, possibly two ribs. The pain has not decreased much during that time. Her appetite has diminished during that time and she lost 7 pounds in just the last week. She has gone from 135 pounds to 113 in the last year. We have hospice coming to do an evaluation. I would appreciate any insight as far as life expectancy and personal experiences.
