That does present like stroke or some sort of brain injury. Hope she's ok
Last I heard it was a side effect of a sever migrane attack. Last I heard she was going to be fine....It stayed on the news for several days here in California...
That was probably a temp clog or reduction in blood flow to the brain that cleared itself. I had something similar happen in my 20's when I could NOT understand a word anyone in my office was saying for about 2 minutes. ANd then it just went away. Doc couldn't find a thing wrong with me. Do you see how she looks scared & frantic for a second when she realizes it's not coming out how she wanted to say it? Poor thing. I had a horiffic migraine at the time.
