My DS8 with ADHD and a language impairment took the WISC V recently. He scored the same FSIQ as he did on the WISC IV. Some scores slightly down (not enough to be outside the 95% confidence interval on the WISC IV). Non verbal reasoning (matrix reasoning) increased significantly.
The WISC IV tester from two years ago noted that she thought non verbal reasoning was a developing area for DS, and she expected his abilities to increase.
I like the WISC V better- I didn't know about the time constraints and discontinues. My DS seems to have the profile you mention and it didn't significantly affect his score.
