The fact that you can't understand what you hear or read is the ADHD not iq. IQ tests are stupid anyways all it tells you is what amount of information you can absorb. My IQ is 127 apparently and i still have trouble in 99% of things.

The low IQ test could actually be because of the ADHD not that you're stupid. I don't see why they even make people do IQ tests anyways if the diagnosis will always end up as ADHD.
