I don't know nothing about non-aspie forms of autism, so I won't say nothing.
But I think asperger's most likely is Mendelian, either you got it or you don't.
The goofy concept of a spectrum might be appropriate to describe the infinite subtle variations in human skin color, but I don't think they describe the life circumstances of an aspie.
Individual variations exist, but there's a huge difference between aspies and the general population.
Genetics nowadays is strong on data collection, but woefully short on theory and thinking. That doesn't produce good science.
I don't think asperger's has much to do with chemistry. I think it involves the physical connections between the neurons. It's the wiring, not the air conditioning. I'm not sure how you're gonna re-wire the brain.
There is a cure, however for the idiotic belief that asperger's is the "extreme male brain" caused by a surge of testosterone. Anybody believing this just needs to spend fifteen minutes over at Love and Dating and check out how those "extreme males" are doing.
I'm not holding my breath waiting for society to become more accepting. Pretty much all animals communicate, group-living animals communicate all the time, and as far as anybody knows, humans are the only animals that have a complex symbolic language. All that communication that's going on is, by definition, nonverbal.
Aspies are really, really weird. not just a deviation from society, but a deviation from the basic nature of the animal kingdom.

Did you say that wasn't proper? Did you march out on the track?
You were quiet, just like mice. And now you say that we're not nice.
Well thank you buddy for your advice...
