I believe she is in late stage dementia. Anxious so can't sit still more than 10 minutes. She can no longer dres herself, can't remember to take her teeth out, can't remember if she has eaten or had a bowel movement. I can ask her a question and she answers with sgomething that has nothing at all to do with the question. It is so puzzling. Does she not understand? Is the brain just not sending signals? I have no idea how to handle her and it is exhausting. She takes remeron at night, Namenda did nothing for her. She still talks but no real conversation can be had.
