Frederic and others: My mother who is now 72 has had PD for about 12 years now. She is pretty much confined to the bed ever since she had a fall and damaged her hip. But at least 5 years before she was diagnosed as having PD, she was diagnosed to have hypothyroidism - a condition wherein the thyroid gland does not produce the normal required amounts of thyroxin. I wonder if any work has been done to study the possible relationship between Thyroid malfunctioning and PD. I would be very much interested in hearing from others. Thanks Shyam
