I agree with hkc. It's hard to draw the line. I think one of the problems is that most of those things can be explained by sensory issues. Lack of eye contact could be hyper visual sensitivity caused by trouble processing auditory information. If a child is in constant motion, he or she clearly has either a vestibular issue or AD/HD.
Also, the meaningful conversations could be lacking because of shyness. I know for example, my son is super shy in front of other people but the second we get home, he'll barrage me with a slew of insightful questions about the person that he met that day.
Hmm. The abstract thinking issue and lack of ability to see things from someone else's perspective is hard one. I can't explain that any other way.
