brain-researchIt’s long been known that Dyslexia and ADD / ADHD have high rates of overlaps or “co-morbidities”. Dyslexia and ADHD co-occur 30-50% of the time (Germano, 2010) and only 40% of children with dyslexia and 20% of children with ADD/ADHD have it in isolation (Wilcutt and Pennington, 2000).

Science has progressed on many fronts over the past 5 years, and both attention and dyslexia are now known to be much more complex than originally suspected.
