My dear husband (71) has had Alzheimer's for almost 10 years now. We are mainly coping with the slow decline of his abilities but tonight for the first time ever he's refused to come to bed and I'm sitting here in bed listening to him coughing( he has other medical problems). I've provided a pillow and duvet but not sure if he'll use them . I've hidden all the door keys in case he decides to 'go home' Not sure what else to do.....any advice out there please.
