Hmm, I'm not sure how to answer your question. I remember the first symptom I noticed (I collapsed). After that, I just slightly lost my balance two or three times a day for a few months. Then it gradually got worse over the next year.

I'm not sure if you'd say my disease was mild or moderate. I haven't had any breathing crises, but sometimes I get weak enough that I can't walk at all, but never for more than a couple of hours at a time.
