I am currently reading Different Minds - which directly addresses gifted children with Aspergers or ADHD (or both). And it talks about exactly what aculady mentions, that on WISC you may see lower comprehension scores, but in a gifted child the similarities and vocab will likely be very high. Sweetie's sons pattern with depressed non verbal is also a recognised pattern according to this book. Which surprised me as i thought that those with aspergers were supposed to be visual spatial thinkers. It's an interesting book.
