I would recommend that you contact Dr. Muenter at the Mayo Clinic in Scottsdale, AZ. He is a wonderful neurologist specializing in PD and a very empathetic person. If he can not see your husband periodically, he certainly is in a position to recommend a good PD specialist in the are. Good luck. Travel safely.
