I can't tell you anything about ADHD, however, I will say my ds has a similar profile: VCI being the highest index (I know yours was the PRI, but both are best indicators of giftedness) and Processing Speed being the lowest,
really low, and our tester didn't bring up ADHD at all, but rather, perfectionism issues. I don't know anything about the other test.
Here's a talk given by James Webb if you haven't seen it. I don't know if it will help or make matters muddier...
