My mother plays in her food or throws it on the floor. The nurses feed her and she will eat all her food. She is wheel chair only so when would be a good time to sign her up for hospice? With dementia Alzheimer's it's just a steady decline in her abilities.
With dementia it is very difficult to estimate remaining life expectancy. In many types of cancer or other diseases it is possible to say "when this happens, and this test result is X and this test result in Y, then it is highly likely the patient will die within the next 6 months." There simply aren't similar standards for dementia. I understand that Medicare needed to come up with some guidelines. What I heard was ridiculous, but that aside, I think getting hospice help as soon as a patient qualifies for it is valuable.
I favor hospice as a compassionate end of life stage.
Good luck
