My OH was diagnosed 6 years ago and has been only very slowly becoming iller, although it has speeded up lately. He has been on Aricept all that time. Now he is having severe and disturbing nightmares: there are armed men in the house, there's a baby in pain somewhere in the house etc etc. despite my trying to calm him and say that he's been dreaming he insists on searching the house (while still a bit asleep) . Sometimes he's having violent fights with people and kicks and shouts. He has always been a peaceful chap and never violent or bad tempered. I have now asked the Pharmacist who says that it would be OK for him to take the Aricept in the morning, which would help with the nightmares. Has anyone any experience of taking it in the morning instead of at night ? Any any ideas about how to stop the nightmares if changing the Aricept time doesn't work ?
