I am "agnostic" about all of these theories, though I am inclined to believe that the more plausible causes are neurological or genetic/epigenic variance,"either which may or may not be caused by extraterrestrial or neanderthal ancestry; with the genetic theory, I believe that it may be possible for the autistic gene to "switched on" due to pre-natal stress/trauma (including anoxia/hypoxia and the mother's behavior during pregnancy), perhaps early post-natal stress/trauma (which would encompass the most extreme cases of maternal indifference/neglect), electromagnetic fields, toxins in the environment and food supply, and/or heavy poisoning, all which may lead to co-morid metabolic disorders that further amplify the symptoms.
I have considered the Indigo/Crystal Child argument as well and am still debating this.
I agree. My vote was for "genetic/epigenetic variance" as a sort of umbrella for some of the other listed causes. If enviromental factors (such as you listed) cause "autism" genes to switch on, I guess that could go under an epigenetic umbrella. I don't think it will ultimately be just one cause. I also don't think it will ultimately be just one syndrome.
The latest DSM folds Aspergers into Autism spectrum which I think is useful (discussed to death elsewhere). The original distinction was not necessarily the right place to make a divide. It seems prudent to not make any divide at this point. But when diagnostic techniques are eventually able to move away from relying on behaviour (and I think that will eventually happen), there may be new divides that come from imaging studies or DNA studies or something else not yet in use. When that happens (and I suspect it eventually will), it may turn out that some of what is currently under "autism" will turn out to actually be different syndromes with different causes, some of which may be on Fnord's list and some of which may not.
