Sorry--I'm in a funk and slipping a bit. I've read that you should be able to move your tongue fast from side to side, (I've never had a neuro ask me to do this). I can't move it that fast (I saw a video of a neuro exam and the guy did it really fast). I can move it from side to side, but not that fast and not for that long before it becomes a bit uncordinated. Anyone else have this problem? Thanks, Denise
