For my part, my now late husband had Parkinsons, with vascular dementia and then cancer of the oesophogus ....it became impossible to care for him at home (although we were lucky living in France our Dr arranged for nurses to visit every day and she would call in when she was in our commune and have a look at him ...the care was excellent, but I had to return to the UK to sort out a deceased relatives affairs ....like your husband he would constantly ask me to take him home, All the neighbours and friends who spoke English would visit him whilst I was away ...he would ask them the same question .......and also, when where we we going to move back to the UK .he wanted a 3 bed bungalow in London suburbs !!!! I said we could never afford that...BUT the home's psychologist said to me, ;the best way to keep him content in being cared for here, is to make him think that when he was better (which he was never going to be)....you will both move ...suggested I take in estate agents details of bungalows in the UK ...so I did ....then whilst he still had his faculties, I also took in a drawing pad and pens ...he would spend hours planning our new garden, drawing up designs and which trees and plants would go where ..........he was then fairly content and happy .....but sometimes he didnt know who I was ...saying 'I dont want you here, send the woman who lives in my house'....so I simply said ;I'll see if she is busy' and leave it at that ! the care home, which was also a 'herbegement medicalisee pour personnes 'age) (old folks home with medical facilities) cost me Euro 4,000 a month which was hard to find ...but all medical treatment was covered by our compulsory medical insurance. So, if your husband has a particular idea (like going home, or moving elsewhere) could be a good suggestion to keep him believing he WILL be home as soon as he is 'better' ...a white lie but may give him some comfort
