I was told today my husband has to now be fed and given liquids from a nurse. He now can't do this for himself. Three weeks ago this started he is as well very very confused can't follow any instructions 12 weeks ago he went shopping picking things and eating himself. I've been told rapid deterioration happens in younger suffers. What will happen in another 3 weeks time? Has this happened to any other younger suffers? How long does he have now?
