The inability to read may be the result of dyslexia. The International Dyslexia Association defines it this way: "Dyslexia is a specific learning disability that is neurological 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."
Here are some of the many talented and accomplished individuals who are dyslexic, or historic figures who had learning difficulties associated with dyslexia or related learning styles.
