Tom, please pass on our best wishes to Cathy and Tom.
My first wife is a Speech Pathologist.  One of her first patients was a ham 
who had a major stroke.  He had over learned the code to such a degree, that 
he could blink it with an eye.  I wonder if Kevin could communicate with 
finger taps or hand squeezes?  If she got a local ham to visit, it might be 
worth a try.  Just an idea.
