Work at Harvard Medical School in Boston has confirmed that the origins of dyslexia are in brain development and it's absolutely independent of intellect or IQ. A small percentage of the population has dyslexia, a reading disability caused by physical problems in the brain. In recent years, amazing advances have been made in understanding what's actually going on, right down to the level of the embryo, individual nerve cells, molecules and genes. Work at Harvard Medical School in Boston has confirmed that the origins of dyslexia are in brain development and it's absolutely independent of intellect or IQ. You see, reading is not a natural activity for the human brain, and each language produces its own stresses and strains on the nervous system. The group at Harvard and others have found that in the commonest forms of dyslexia, tiny parts of the brain associated with language processing haven't developed normally. The nerves may not have connected as they should have in the embryo, probably because of faulty genes. The result is that sound and occasionally vision processing is slower, making decoding the written word much harder. It gives comfort for parents that they are explanations for their children's problems and proves these kids aren't dummies as they're often typified. The next step is improving the available treatments for dyslexia to match the biology.
