What is Dyslexia?
What is dyslexia and what does it have to do with speech-language? Dyslexia is a specific language processing problem that can best be evaluated and treated by those who match learning styles to learning needs by specifically teaching reading, writing, and spelling using multi-sensory structured language techniques.
The formal definition given by the International Dyslexia Association in the Annals of Dyslexia is the following:
“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.” -Annals of Dyslexia (January 2003, Volume 53, Issue 1, pp 1-14).
Adopted by the International Dyslexia Association (IDA) Board of Directors, Nov. 12, 2002. This Definition is also used by the National Institute of Child Health and Human Development (NICHD). Many state education codes, including New Jersey, Ohio and Utah, have adopted this definition. Learn more about how consensus was reached on this definition: Definition Consensus Project.
