Dyslexia is a common condition that affects the way the brain processes language. Dyslexia makes it difficult for students to read and spell, but is not a sign of low intelligence. The Alabama State Department of Education (2015) defines dyslexia as a "learning challenge that is neurological in origin and 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 delivery 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."
