My 93 yr old Aunt (second mother to me) says there are people that come to her house at night & stay with her thru the night & leave in the morning. She says she speaks to them but they don't answer. She has no idea where they sleep, but they spend the night. We know she has no one visiting but aren't sure what this means and should we worry. Her sons are in the process of hiring daily part-time help to see that she takes her meds & eats enough. I check the fridge weekly & see that very little in the way of food is being used & I know she's not drinking enough fluids. She is on her second urinary tract infection w/antibiotics.....the last one left her dehydrated severely & showing stroke-like symtoms......she ended up in the hospital & rehab for a couple weeks. But her sons keep having her come home to rehab instead of a nursing home.....but then they leave her alone way too much.
