Mom was telling me that when I was young the home town doctors name was Dr Doobie. She kept talking about him, I just said really I don't remember, and tried to change the subject, but she kept going back to it. But the way she was looking at me to see what my reaction was , was confusing to me. So anyways, i asked everyone I know that age era , and they never heard of him.
It really honestly makes no difference to me. Just thought maybe she is making stories up
While "confabulation" is common with patients with any mental deficit (as well as the general public at large, in fact), it is rare that things are "purposely" made up.
The brain of an Alzheimer's patient is confused. There is no intention to mislead you.
Next time if redirection doesn't work, open YouTube on your phone and show her funny animal or people videos. If that fails, literally walk away. I know this doesn't feel good but when your time gets drained by untrue, pointless stories every day, several times a day, this may become the only solution. It's what i do with my Mom when she goes into paranoid rants about my well-loved cousin. I just can't suffer it.
Dad had a drawing of a dog that looked similar to the dog that he and Mom used to have. He insisted that he'd drawn the picture. He hadn't. It was signed by the artist and he'd bought it at a shop.
Rude Aunt believes that Dad has been appearing to her in dreams and instructing her that she should never allow anyone else to get his business. Unfortunately, he's dead, and long before he died, he planned for continuation of his business, which didn't include her (which irked her to the point of having these dreams and talking about them to everyone - if she even had the dreams and wasn't confabulating the whole thing).
Another person I know has personal knowledge that her husband was inhabited by a demon when he was five. She wants others to believe it too.
Oh, dementia patients can come up with some stories, all right.....
You say in your response to Alva below that you are educating yourself about dementia, but with some of the questions you have, I have to question just what exactly are you reading or watching, as you don't seem to be grasping what having a broken brain means.
May I suggest just one book that pretty much explains it all and will help you better understand dementia, and that is the book The 36 Hour Day by Nancy L. Mace and Peter V. Rabins.
If you don't understand dementia after reading that book you never will.
