My grandma is 93 with advanced stage Alzheimer's. I am wondering if her end is drawing near. She has been slipping out of chairs, today she is lethargic and she was started on an iv. She doesn’t want to eat. She doesn’t walk well with out assistance. She is in a memory care unit. I have never been through a loved one with Alzheimer’s before, not sure if it’s a sign of the end or just a bug.
