My mother insists I am making faces at her and I am not. Anyone else experience this?

I am a 39 year old woman taking care of my 67 year old mother. At this point she does not have a diagnosis because she has refused to go to the doctor for years. I ended up moving in with her last year due to my divorce, and just before my stepfather passed away. At this point I’m making the assumption that she has dementia. I’m sure she has several serious health problems right now. She has a doctor appointment scheduled at the end of this week.

There are some times when I will leave a room and come back in, and she will ask, “What’s wrong?” or “What’s wrong with your face?” There is nothing wrong with me. Sometimes if she says this, I’ll go and look at myself in the mirror without her knowing and make sure I definitely have a neutral face. When I return, she says the same thing. I thought maybe she was trying to instigate an argument, but there was nothing to argue about. She will say this when she is relaxed and also when she is agitated. I can’t figure a pattern to it.

I look younger than my age, and she said the same thing before and after I got Botox. It looks very natural and she doesn’t know I got Botox. So I’m definitely not scowling though.

Today she said, “You were twisting up your face and making faces at me last night and I don’t know why you were so moody.” I was tired, but honestly don’t remember making any faces.

Perhaps this is the beginning of her not recognizing me. She didn’t recognize Jennifer Garner on a commercial we were watching that has been on tv for over a year now.

Has anyone experienced their LO insisting that you are making faces at them when you aren’t? Perhaps it’s a vision issue? She got new glasses last December.
