It's gotten so bad my mother doesn't even remember or recall when she's calling out my name. Any suggestions?

Willy my mom used to call out almost constantly - C_____, C_____ can you turn me over? She didn't need turning, in fact sometimes she was sitting in a chair. Sometimes she needed something else, often she didn't know she had called or what she wanted. There were days I just wanted to yell SHUT UP!!! Thank goodness she couldn't get up without help and I never had to worry about shadowing or her getting into things when my back was turned!
Anyway, the doctor prescribed mirtazapine, an antidepressant, because she was awake through the night and it helped with the frequency of the calling too. Don't be afraid to try medication, mirtazapine may not be appropriate for your mom but something could be helpful.
