It’s truly hard to distinguish the difference. Example:
I will talk to her and she seem just fine a few min later my sister will talk to her and she tells her this long story of how sick she was all night threw up everywhere and has been cleaning it up. Never mentioned it to me. Then a few hours later we ask her about it and she acts like she doesn’t know what we are talking about ... is that possible? Is it dementia and memory loss?
The most important thing is to not argue or try to convince her she’s talking nonsense. It’s not nonsense to her. Just go along with it. Tell her you’re sorry she wasn’t feeling well and change the subject.
I try not to correct her, because in her mind these are her truths and she will defend herself with a passion. As you mentioned mom may make an crazy accusation and if you ask about it later she’ll say something different. Unfortunately there’s no reasoning with a broken mind.
I wonder where they get the ability to free form these stories? It's worrisome for many reasons. But I'm thinking safety issues because there may be non family members without good intentions.
There's a sort of word salad, mixed up sentences/memories/ideas that some people get. Sometimes triggered by a word. Like if someone said the word *sick* a story/memory may be prompted. So hard to know but worth mentioning to the Doctor to rule out other causes.
Do you know anything about this type of Dementia ?
