Dyslexia and Development: Neuro-Biological Aspects of Extra-Ordinary Brains

"Dyslexia and Development" presents recent findings of neurobiological research, which suggests a link between seemingly minor brain abnormalities and epilepsy, learning disorders and autism. The authors focus on the plasticity of the developing nervous system and the possible role of subtle early brain injury in the emergence of these disorders, particularly dyslexia. The contributors to this volume examine epidemiologic and clinical issues that may make the developing brain more vulnerable to environmental and genetic influences, which can in turn lead to abnormal brain plasticity and behaviour. Although major forms of brain malformation have been clearly associated with functional deficits, mild forms have historically been ignored or trivialized; this book supports the hypothesis that several types of such malformation reflect brain injury during critical stages of development, and also the premise that more and more disturbances of thought and behaviour stem from abnormalities of brain organization. Neurologists and neurobiologists, psychologists, psycholinguists, psychiatrists, and special educators will find here a guide to more enlightened understanding and more effective treatment of dyslexia. In fact, the book emphasizes the positive aspect of the neurobiological deviation that dyslexic brains seem to show, along with the observation that people with such brains are often quite creative and "extra-ordinary", rather than handicapped. In turn, the revised consideration of dyslexia should lead to more serious attention to other disturbances of childhood behaviour as problems in developmental neurology, as well as to a deeper analysis of possible neurological bases for individual differences in normal behaviour and personality.
