My grandma is, I don't know what the "correct terms" are, experiencing dementia. She has a hard time remembering things, and she knows it. Most of the days are very hard for her and the family. My mom had been telling me for a couple weeks that Grandma was talking to herself a lot and that she says the same things over and over. But until I saw it, I had no idea what that meant.
It's almost impossible to talk to her. She is so focused on remembering things. She repeats herself over and over and over constantly. It's hard. It's really hard.
