Your post caught my attention when I was browsing. When I was in grade 9 I was diagnosed with ADHD and had very similar results to your son!! This is so interesting! My mom just recently showed me my papers from it. My processing speed and visual spatial were the highest and I had a deficit in verbal expression. I'm 24 now. I never would have thought I would find someone with the same diagnosis and iq numbers as me. I was on here looking for my kids, lol. Feel free to message me if you ever have any questions. Take care!
