I'd like to make a comment here without being attacked. My beliefs are that lack of eye-contact is a function of toxicity in the brain. I know that most of you are "therapy"-based people, but there is a growing number of people who believe that these neurological disorders are indicative of heavy metal poisoning.
I have my own experience to back this up as my oldest DS had numerous tics and ADD tendencies. After a few months of mild oral chelation, the tics were gone. Anyway, I thought this was an interesting link......
