I help take care of my 94yr old Grandma with the late stages of alzheimers. We lost Grandpa in July from malnutriution due to alzheimers. She doesnt remember he is gone or that her bro/sisters are all gone too. Why wont she sleep at night, she wonders about yelling for her sisters/gra-pa and the ghost children she sees. If she is not up wondering around she is yelling from her bed and just wants to know what we are doing or where some one is or to put the kids to bed. (there is no kids)We have tried to give her tylonol pm at bedtime instead of just regular tylonol and it doesnt seem to do anything. ( she has severe arthritice pain.) I cant go to work everyday on 3hrs sleep and then come out when I get off to help with her and start all over it is stressing me out and I just want to yell at her. Any suggestions on what to do to help her sleep through the night?
