I was talking face to face with my elderly Mother when she had a TIA. She was not even aware she was babbling incoherently.
I just went through this with my elderly mom, out of nowhere she just started talking in what seemed like something you would see on the exorcist scared the hell out of me!! Since that episode a month ago she has seemed confused at times she has not had the vaccine she lives in my home and I make sure she stays safe!!
That must have been frightening. I hope that she recovered.
