That same thing happened to my girlfriend's grandpa last year. No amount of doctors could figure out what happened to him, but he was manic and could not speak. It would just come out jibberish like that. He could write fine, but when he tried to speak it would make no sense.
He spent a month in the Psych ward at the hospital and it went away. As far as they could tell he hadn't had a stroke or seizure. No idea what happened to the disconnect between his brain and his mouth.
I havent seen anything that states exactly what happened.. sorry to ruin the fun...
"CBS reporter Serene Branson was reporting live from Los Angeles after the Grammy Awards when she began to flub her lines. What initially seemed like a minor slip-up quickly delved into slurring and an undecipherable word scramble, from an increasingly worried-looking Branson.
The Telegraph reports that Branson was hospitalized after the episode, as sudden, inexplicable difficulty with speech is one of the characteristic warning signs of a stroke.
Nah, she's fine... just a momentary lapse of retardation. Maybe Usher was trying to make throat babies with her.
"Serene Branson was examined by paramedics on scene immediately after her broadcast. Her vital signs were normal. She was not hospitalized. As a precautionary measure, a colleague gave her a ride home and she says that she is feeling fine this morning."
