Dad is now 80, still lives alone and has taken to calling us in the night. Often asking where I am or what's happening next. Last night he rang at 4:00am (Uk time) wide awake wanting to know when I was coming over. I am finding this new stage hard. My husband has to get up early for work, we have school age kids and to honest I'm exhausted. What stage of dementia is confusion of day and night? He does not seem to know how to rest or sleep at night and how can we or he function with his confusion and restlessnes? Feel alone, no sibling help or other family friends support. Apologies for the rant but any advise greatly appreciated.
