My husband will not wash properly or clean his teeth because he won't believe the toothbrush, razor etc. Is his because he doesn't recognise the house we live in as his, where he has lived for over 50 years. Every evening he just wants to 'go home', but he doesn't know where home is. I have to keep the doors locked because he wants to get out and gets very angry when he can't. I have tried walking him 'home' and coming back but it's not possible every evening, especially on dark nights.
