sysdharma posted[1] about an episode with aphasia[2]. I
recall there was an instance of this happening to a TV
reporter a year or two ago, during a live broadcast. She
tried to continue speaking, but only gibberish came out.
You could tell by the look on her face that she was very,
very concerned. I can only imagine what it must feel like,
though sysdharma did a good job describing it.
Get well soon sysdharma, hopefully you find the cause or
triggers.
