I have a distant relative, and I heard through the family grapevine that he was diagnosed with MS about 5 years ago. Then I heard he was being given Avonex. But when I heard of the symptoms he has, I was thinking maybe he doesn't even have MS. Now, a year ago I heard he was being given Adderall. Is Adderall commonly used to treat MS? If so why?

I'd appreciate anything anyone knows about this.
