Hi Anthony,
The day I was diagnosed I was informed that sadly, at present, there is no cure for AMN. However from the info that i've read online over the last 3 or so years it looks like we can glean hope from the advances made in stem cell research and also gene therapy - it's just that it may be a while. I have a friend who's wife has MS (which like ours is a de-myelinating disease) and, through talking to her, I often read news stories online that bring real hope for us all in terms of MS-related medical breakthroughs.
From your profile I see that you're 22 (I turned 38 in May) and I believe now that I started experiencing the early onset of AMN around 28. My point is that at 38 i'm still very much facing AMN head-on and by that reckoning when you get to 38 you'll still be very much fighting-fit as well!! So, as far as research goes, that's 16 years worth of scientific advances and (as my consultant pointed out to me) that's a long time in medical terms!!
The best personal advice I can give is stay mentally and physically active and be wary of "alternative" therapies (i.e. scientifically unproven).
Here is another great online AMN forum for you to look at:
