My mum is 82 and has been in care home since last November following many weeks in hospital,dehydrated,severe weight loss etc.She hasn't been diagnosed but definite signs of dementia,my Dad has advanced AD so have been here before.Mum has had 2 strikes,several TIA's and is physically in a very bad way,incontinent,needs feeding,washing,hoist required for transfers,can't even change position in bed or chair.Despite all this manages to cook,do housework,go for a walk.I'm sure you get the picture.Anyway she was taken into A and E a couple of weeks ago after a funny turn,tests inconclusive and was discharged the same day.Then told that follow up x ray needed as original not very good quality,she had x ray on Monday,have just been told there is some shadowing and tests required to rule out lung cancer,1st step is CT scan.I don't know what benefit will come from this as she would not tolerate any aggressive treatment.I don't have POA for health and welfare.Any advice?
