Alzheimer's question?!

Alzheimer's question?

My mom has alzheimer's. She has had it for 10 years now. Only the last few years have been kinda bad. But....just this last month, she can no longer walk, hold her head up, won't eat, talk, nothing....so...do you think she is near the end? She is just losing it real fast really bad. Just this last mother's day, she would say a few words and giggle at me for being silly with her. Her head was starting to hang down, but I could get her to look at me. Now, it's just down almost completly, like she can't even hold up her head. No reactions on anything now. Just ..... blankness. I know I really lost my "mother" a few years ago, but, do you think I'm going to lose the rest now? Are these the signs that the end is near? Is she giving up? Does anyone know anything on this matter? Thank you.

My thoughts and prayers are with you as your mother is entering the final stages of Alzheimer's.
My mother has dementia, hardening of the arteries in her neck is causing not enough blood to get to her brain. I can sympathize with the uncertainty and emotional roller coaster you are on right now.
Please continue to talk with your mom since there is the possibility that she can hear you even though she cannot respond to you. Also, hold her hand or rub her back. Human touch can mean so much, more than you will ever know.
