Frederic (and others), I also am interested in knowing more about any relationship that might exist between PD and the thyroid gland. Before she was diagnosed with PD, my mother consulted a homeopath who suspected something was wrong with her thyroid. Like your mom, she also has bouts of anxiety. I will look for more information, but I'd like to know more about your mom's symptoms and surgery, as well as anything else you learn. I'll keep your address (which is HUGE, and variable, it appears once as @esu32 and once as @esu36). And I'll let you know what I find. Dan Dettweiler [log in to unmask]
