It's a horrible way to go. As an early teen my grandma went through it. We would find her hiding from her abusive ex husband who had been dead for forty years. She would call the house at 3am, I was told to not answer the phone and of I did answer to hang up on her nectar she would talk at great length about how she could feel the worms eating her skin in her grave. It was really awful to watch as a kid and I'm sure it was much worse for her. She didn't do well in a home after that and would attack the nursing staff negate she didn't know who they were. That shit of horrifying. I think if nothing else, Alzheimers is one hell of a great reason for assisted suicide.
