Dyslexia is a specific learning disability that is neurological in origin. It affects reading and related language skills such as fluent word recognition, word retrieval, reading comprehension, spelling and composing written sentences.
Some people with dyslexia have additional weaknesses in working memory and organization. Dyslexia may also occur concurrently with other learning disabilities, such as dyscalculia (math), dysgraphia (handwriting), ADHD (attention).
