The empathy part was explained to me as kids with ASD DO have empathy, but have problems expressing (communicating) it. My DS never had a problem with empathy, but it has always been what I would call inappropriate expression (too much or too little...bawling for hours over a dead tree, yet turning away if a friend falls and is injured) which seems to fit in the "emotional OE." I guess I am being silly about caring about a label...he is who he is. I am a little shocked that after 5 years with an ASD label no one mentioned overexcitabilities.
