My Dad (86) has Alzheimers. He lives with his partner of 7 years in her home (he was widowed 20 yrs ago) and they are devoted to each other. However, recently when his partner goes out (grocery shopping for example), Dad loses all track of time and thinks she has been gone hours. He gets very distressed left alone and phones us to say she has been geon hours, that she has left him and is probably seeing someone else (she is 76 and spends her life looking after him so highly unlikely!). He doesn't realise how bad he is and gets cross if we suggest he has lose track of time or is being unduly suspicious. Does anyone have any experience of helping an Alzheimers sufferer keep track of time or any other helpful suggestions. Thank you. Sev.
