My husband would speak to me in his native language when I told him I did not understand him he would be angry and confused. He thought I was his sister and couldn’t understand why I didn’t understand him, so sad for both of us, he was forgetting who I was. He passed in Nov of 20 I don’t think he knew who I was anymore.

My wife talks in her sleep

Yes my love has "different languages" too:). I love it! Mostly when we get up. He's always been a morning person. He can speak Asian also and Native American. Bentley our fur-human just gives him this look:):).

HUGS! KEEP ON KEEPING ON!

Ernie isn’t capable of finding the right words. He doesn’t know he is using the wrong words most of the time. He is in the final stage of his Alzheimer’s/Dementia, and completely bed bound since he forgot how to walk.
He also has lengthy conversations with others that are not there only he is awake. He used to only do that in his sleep, but now he will do it with me sitting right there. I brought him his dinner, I have to feed him, he forgot how to do it himself, and I told him it was time to eat. He looked past me and waved at “someone” and said “I have to go, thanks guys, I appreciate it”. I haven’t heard him talk that clearly for a couple of years!

My husband hasn't done this. In fact he is at the he stage that finding the right word is hard and he'll give up talking out of frustration. But in his sleep, he has long flowing conversations. I can't make out the words but the flow of his speech sounds like he is lecturing or teaching again.

Yes, my husband went thru a stage where he was talking, and it was all gibberish but not to him. I found rather than trying to get him to explain I just nodded along and said reassuring things. He did this for a few months in spurts then it stopped. It seemed to me like the brain was misfiring and just going bananas, so we just went with the flow...easier in the long run!

My wife was a Spanish teacher for 22 years. She lost all of the Spanish over time. She, for a time, would speak in a babble. Often it was happy and animated. Toward the end that would stop. Short episodes of speaking in a childlike voice, but not that made any sense, and not very often.

Donna my Grandparents we’re both born in Italy so all their kids had to speak Italian at home.
I know what you are saying about postponing surgery I am doing the same. I have to help my wife out of bed, out of chairs. And off toilet. 💜

Just reassure him everything is alright
