Is the above a part of dementia? It never fails, mom will ask me a ?. I start to answer it and she either changes the subject or cuts me off with another topic of conversation. It drives me crazy. She did this to me two days ago and just just stopped answering. She starting pointing something out in the middle of my answer. She noticed I stopped and said, Oh I'm sorry go on. I refused and told her she does this all the time and wasn't going to continue. It happens ALL the time. She also feels a need to talk costantly. She reads all the road signs, narrates everything she see along the way. It's like, whatever is in her head has to come out her mouth. If I see a cow, I don't have to say there's a cow, she has to say there's a cow. It drives me crazy. What is causing this?
