My husband looks after Alzheimer sufferers for a living. It's very poorly paid work and there's no job security, but he loves it.
BBC 2 is showing a very good series about care homes (and most residents in care homes have some form of dementia) by Gerry Robinson. I saw it the other night and it almost made me weep. There's so much more that we as a society could and should be doing for these poor people.
