Yes, it's hard to say. They find that MS tends to "run" in families, but not that there is a direct hereditary "genetic" link. Yet, anyway. IF they ever find an exact "gene" that is screwed up, then they'll be able to connect the dots, as the saying goes.
I guess I shouldn't have said I'm in limbo previously. The fact is, I was told flat out:
You do NOT have MS. You do NOT have ALS. You will NEVER be disabled. You are NOT going to die!
I'll have my ups and downs periods (like I have always had my whole life), but what else is new, huh?
In any event, the meds I'm on help a whole range of neuro type diseases anyway, including MS, so even if I ever DID have it, I don't now. And if I never did have it, then the meds I'm on are still the right meds for everything I DO (or might) have. And besides, let's take the middle road........the way I put it is like this. The meds I'm on will help keep me well, and based on my research, will also thwart my "predisposition" to MS, too. So it's a win/win situation.
