yeah, because of prenatal screening.
nah, they've actually pinpointed the cause as pollution exposure in utero.
Yeah, and it does make sense. Mothers who have a child, and it is autistic, then the next one is slightly less autistic, and then the last one is perfectly fine. So yeah, the word pollution makes sense, as it takes a few years to clear out nasty stuff once it gets into the system. I know, because I am dealing with epilepsy due to a natural food product.
