I don't know my Florida geography, but I think Dr. Perlmutter, The Renegade Neurologist, practices in Florida.

If you back track to his blog, and search gluten... you will find he is most definitely aware. One of the "most" aware... possibly more aware than the folk at Mayo... who may still be more concerned with celiac disease... and gluten sensitivity can most definitely cause neurological disease without necessarily testing positive for celiac disease (as defined by biopsy evidence of intestinal villi damage). Check out The Gluten File in my signature for more info on on gluten and neurology, testing, Dr. Hadjivassilious' research, etc.
May be worth the drive to see Dr. Perlmutter, if he is within a day's trip. Or perhaps, his center could recommend other doctors in your area who are enlightened.
