Dyslexia Defined

  • 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
