Dad is in moderate stages of Alzheimer's and although we,re managing care fine during the day, nights are HARD! My brother is main carer and is fantastic and I have stayed tonight to give him a break. It's now 4am and dad hasn't slept at all, wandering around the house. He's not sleeping during the day either and I'm getting really concerned about how long we can all keep this up. His specialist prescribed lorazepam l1/2 mg increased to 1mg which had no effect only made dad unsteady on his feet, and we have run out anyway. The specialist said my dad can't be left unattended but if he doesn't sleep I have no idea how we can manage that. He's far too able not to be at home with us but he hasn't had a nights sleep for seven days now and looks so tired it's heartbreaking. Am going to contact specialist later this am but not sure what he can do. ideas anyone?
