Definition of dyslexia
Dyslexia is a specific learning disability that is neurobiological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge.
The causes of dyslexia are varied and not fully established. There are two types of dyslexia—acquired and developmental. Acquired dyslexia can be caused by ear infections early in childhood that result in hearing problems. Developmental dyslexia is caused by congenital and developmental factors; scientists believe that dyslexia has a genetic component that may predispose some people for dyslexia. Although the specific causes have not been fully investigated, neurological abnormalities are introduced in the brain, which can make it difficult for the dyslexic to read and understand information.
