My son has CAPD and no signs of ADHD. He is much better orally and visually than with paper and pen tasks. His processing speed is fairly high average but probably lowered because of his dysgraphia not CAPD. He had a year of speech therapy and seems to have improved tremendously and is now average or above average in all areas.

When we did the CAPD evaluation, the audiologist did some testing that can tease out ADHD traits from CAPD. My son had no signs of ADHD with his testing.
