My 85yo mother’s dementia has progressed significantly but she can still make enough sense to fool you as long as you don’t talk long. After that she repeats the same questions asks off the wall questions forgets 2 minutes ago all the way to 30 plus years ago. She cries and begs to go to the dr and when we get there she smiles and says she’s fine. When they leave the room she will ask me where are we and why are we here? She has pulled some of her hair out and has developed a constant “tick” of picking and rubbing her face and head. I feel like the doctor thinks I’m exaggerating but it is so much worse than they know. What should I do?
