My mom exhibited A's characteristics several years ago but it hasn't progressed like A's. I think she has plain old dementia because she is aware of some things-- she wipes her mouth when she dribbles. When she likes something she says, "That's good!"
Mine is 91 and takes her vit C and CELL FOOD plus Km, a mineral supplement, daily. She takes no Rx drugs except an occasional antibiotic.
She has no pressure sores.
My mother is still enjoyable even if she doesn't know what she's saying. Everybody who comes here to check on her just loves her. She does something to make me laugh every day.
You are a wonderful person. God us watching over you.
