Me personally, I speculated cancer or something like like early in the series but now I have tossed that out and think it was 'mental illness,' at least to the natural world. Was the supernatural involved? It is a very high possibility in Beacon Hills. The town obviously has supernatural roots, hence the Nemeton.

There's actually a hereditary disease mention in an episode of law and order SVU, I think it's called familial fatal insomnia or something. It's really super rare, in rl only about 40 families world wide have a history of it, but the symptoms seem to fit from the little we know. There is also a sporadic version that comes from a random mutation, not inherited, but if you have a random mutation, have a kid does that make them more likely to get it? I don't know.

But like you said, it could be a supernatural problem that they just found a disease to fit. After all, if it looks like a duck, quacks like a duck it's a duck, not a falcon.
