I have read that it's typical for gifted kids to have processing speed and working memory scores significantly below their other scores but have never seen any numbers attached to that statement. Can anyone tell me how much is too much? Our psychologist thinks my kid has ADHD and he might but I want to be careful not to read too much into something if it's "normal" gifted kid stuff. His WISC-V scores are...

Similarities 19
Vocabulary 19
Block Design 14
Matrix Reasoning 19
Figure Weights 18
Digit Span 11
Coding 11

GAI 151
FSIQ 141

Our psychologist is in the process of figuring out the new extended norms. She said his Verbal Comprehension Index is actually 168, but I'm not sure how/if his Fluid Reasoning or GAI/FSIQ scores are impacted by the new norms. Even without extended norms he has a fairly large discrepancy going on. Does this necessarily point to ADHD and/or a learning disability or is this typical for kids in this IQ range?

Any insight is appreciated, thank you!
