No expert, but it looks like the early stages of dementia. I have seen this type of behavior in people at the onset of dementia. Jumbled words, loss for words, incoherent verbal activity. It appears her mind has the words but she is lost verbalizing them. Sad to watch.
She’s like 75....we all loose it.
I’m In public right now so can’t watch the vid but different people are affected differently by dementia. My dad got that aphasia right away and within a few years could not speak. He could get out a string of “word salad” but couldn’t say what he was trying to say. My mom speaks so
Perfectly she could fool you she doesn’t have Alzheimer’s, for a short while.
