ReefGrammie. I know that is tough. My Mom was fine until 93 then she started to forget who I was.
We also put her in an assisted living and naturally that progressed into a nursing home. It was tough but you really can't take care of elderly people at home indefinitely. You try but after a while, you also have a life and they are 24/7 responsibilities.
Years ago our parents used to die when they got very old because they didn't have the means to keep them alive. Today we can keep them alive forever with medications, but I am not sure thats the best thing when their mind is gone. It is very tough but eventually I let my Mother go as there was nothing left in her to save even though her heart was beating.
After my Mom forgot me and didn't know where she was, it almost didn't matter where she lived as long as they were very nice to her, kept her clean and tried to keep her interested in something as after a while we all kind of revert back to our infancy. She also lost her ability to speak.
My Mother lived until 99 years old and passes away of old age with nothing physical wrong with her.
She never took a pill, not even an aspirin and didn't wear glasses.
As soon as my Mom passed, my wife's Mom started the same way and we also put her in the same assisted living and then nursing home. My Mother N Law lived in the same house as us for over 40 years and she was a Sweet heart.
We do what we can as much as we can but it is a hard time in your life and isn't easy seeing the people who raised us and were so vibrant to deteriorate in old age.
