My husband is having very regular periods of not knowing me and our home. This is tending to happen at night when there is no proffessional help. He gets really aggitated and keeps ringing me when I am sitting beside him but still wont accept that I am his wife. He wants to go home and says he will ring for taxi. We walk around the house and he can tell me where each room is and even the colour of the throw over the bed but still will not accept the house as home. He becomes aggressive if you try to get him to understand he is at home. We have lived here for 46 years. His nurse and OT advise distractng, well that does not work. He has been given medication for sleeping as this is another problem but this does not work anymore and our doctor says there is nothing else. So he never sleeps which means I never sleep. Neither of us get any break from this illness and I feel that he lives in permanent torment. I can't begin to imagine what it must be like to be like this. He now goes to daycare three days a week which gives me relief until I collect him then it starts all over again. Has anyone any suggestions of helping him as the distraction theory does not work.
