I was just reading an article that stated that very thing. In fact there is a lot of good info here on different diseases besides MG. I am sure they want to sell you something, but it seemed like a complete and well rounded source of information from what I read.
I can't post a link right now, but the name of the page I was looking at is Health Extension then the sub page is Health concerns. There is a drop down box with lots of health conditions.
