My boyfriend's dad is 61 years old I believe, and according to this site: Stages of Alzheimer's he is for the most part between stages 5 and 6. If dressing on his own, he will generally put his shoes on the wrong feet, only put one on, or mismatch them. Put his shirt on backward. He gets frustrated talking because he usually can't remember what he was about to say. He remembers names and faces, but I would bet he doesn't know his phone number or address. He rakes the yard constantly, 6 hours a day usually, he doesn't like to sit, so much half the yard has turned bare. He has difficulty doing normal tasks, like getting ice out of the freezer, and can't remember for anything where he puts stuff. When he vaccumes, he will do it for hours, not remembering he already vaccumed in that spot. Yesterday he was mopping the tile, and moved on to the carpet and mopped the carpet for about 45 minutes unaware that carpet is not meant to be mopped.
My question is - will he die from this disease? Is there any way that you could guess how much longer he has left, or is alzheimers simply a disease that impares the memory? If there is a way to tell how much longer he has left, what would your guess be?
Thank you :(
