OMG! My father had demetia for a long time. His hands shriveled up and his body was like doll relative to his head. He could not form any speech and not because of the brain damage but because of the nero degeneration (granted his brain damage was such that if he could speak it would make no sense because that was the way he was the last time he had the capacity). End of life on a bed eathing through straws I so hope that is not my end.
