My Mother had one of these.
I went to get her for lunch and she was doing the same thing. Scared the you know what out of me.
I took her to the er and after tests the Docs said she had an eschemic stroke.
By the time we left she was speaking just fine.
Very scarey. She didn’t realize what had happened either.
This happened to my father a while back. We were having dinner and all of a sudden, he was speaking and the words did not make sense. But he never stumbled, stuttered, or slurred his words...the words that were coming out just didn’t make sense. We all sat there looking at him and going, “What??” and then this look of absolute panic came across his face. That was when we knew something was very wrong. He was fine immediately afterwards, but we took him to have him checked and he had had a TIA. Very scary stuff.
