Okay, if they think prolonged mental stress or physical stress causes Fibro and it is related to the same part of the brain as Parkinsons, what causes Parkinsons. Could it be the same thing? I don't know that much about Parkinsons except one doc told my Dad he had it and I thought he was wrong so I had him get more opinions. The doc was wrong. I bring this up because I'm watching True Hollywood Stores about Michael J. Foxx (for about the fourth time - I just love him!). It talked about the time when he was doing the Back to the Future movies and working on Growing Pains at the same time. He sometimes would only get an hour or so sleep and he went on like that for a long time. For me, that qualifies as physical and mental stress. Just wondering if there is any correlation. Maybe someone else knows more about Parkinsons than I do.
