Here is a slide share from a webinar that the Eides did a few years ago. Slide #26 gives a graphic representation of how dylexia presents differently in gifted versus non-gifted learners. I found it helpful when I was trying to understand why my kid didn't fit some of the standard dyslexia red flags.
