Just checking in on this issue. As you know, demon possession is mentioned quite a bit in the new testament. When it's symptoms are described, it sounds a lot like autism or other forms of mental illness.
Demon possession is not isolated to the New Testament, or even to Christianity, but the one commonality is that it is believed in generally uneducated, third world societies (note that I am referring to the belief that specific people in your community are demon possessed and that they can be exorcised. Not just the abstract belief of demon possession. The idea that demon possession is possible is not the same as believing, along with the rest of the community, that your neighbor two doors down is currently demon possessed.)
Given the fact that demon possession doesn't happen in an educated, first world society, it seems to reason that demon possession, as recorded in scripture, is actually a reference to the mentally ill. Unless you think demons purposely only possess people in poor, uneducated communities....
