...more thoughts....I didn't realize there would be so much interest here. Since I have MS I constantly hear of new research and ideas from concerned friends, and I also follow research news. Frank, if you're a researcher, I know you are aware of all the quackery and "well-meaning" advice that often just doesn't meet with strict research controls. That being said, I think you're on the right track to consider all ideas with an open mind.

In MS therapy, I've heard that Tai Chi and horseback riding have been looked at for improving physical movements.

Since Tourette's seems to have a significant genetic component, is anyone looking at all the new gene research? In the last two years, a subcategory of MS called Heritary Biochemical Multiple Sclerosis (HBMS) has been researched and written up in Human Genetics Journal (I think). This appears to be a heme synthesis disruption and has a strong genetic link to people of Scottish descent. If you're interested I can find more info. I think some people have been treated metabolically.

Back to Tourette's, stroke, brain damage and music. I really feel that learning theory would lend the most insight into understanding the effect music has on various people, regardless of brain damage or not. I've lost touch with all my resources in this field, but I think you would find them under educational psychology/learning theory.

Keep us informed.
