I did the Vanderbilt assessment and he scores high in the screening for ADHD inattentive and Anxiety. It's a nice little screening tool!
Regarding decoding or comprehension, I think it's comprehension. I do get a little confused on what it means that kids with aspergers have great reading skills but little comprehension. DS loves fiction, not long ago read the percy jackson series and made up his own fantasy where he was the 13th greek god (not just a demigod as he would tell me) of immortality who would confer immortality to all around him. He also seems to get abstract thinking fairly well. ...at least I think he gets it. But he definitely has some aspergers traits.
