How old? My DD had a similar profile (on the WISC-IV) at 9 and was (finally) diagnosed with autism spectrum disorder at 12. ADHD / SPD / Anxiety are the "unholy trinity" that my school counselor has told me leads her to treat kids as undiagnosed ASD until it is ruled out by an expert. On the other hand, her tester told us that a lot of gifted kids get artificially low scores on Comprehension because they give correct-ish answers that are outside the scope of answers considered correct by the test designers. On the gripping hand, she didn't identify DD's ASD, either, and in fact told us that she thought it was unlikely.

So now you probably know less than before.
