I saw this on a website about dyslexia:


"But where dyslexia is identified, between a third and a half of children have a history of learning difficulties in their family, and more than half have a family member who is left-handed. However, the brains of dyslexic children show an unusual variation in left- and right-side activity. Recent research has found that, whereas non-dyslexic children use the left side of their brain for language work, dyslexic children have to use the right side as well."
