Dyslexia is an oral-written language learning disability (OWL LD) that is associated with language deficits from early childhood. Specifically, dyslexia occurs when a child demonstrates phonological difficulties but other issues can be present, learning to decode print and reading comprehension problems. In early childhood, children with phonological problems are often slow to develop speech and language, may have multiple speech errors and problems with word-finding, grammatical forms and following the ‘flow’ of conversation. These problems are not related to intelligence but to differences in how our brains process linguistic information. Language disabilities result in learning disabilities and can affect children’s social as well as academic success. Diagnosis and treatment are evidence-based and comprehensive, moving from a strong phonics base focusing on sound-letter spelling patterns, morphology, text navigation strategies and critical thinking. Handwriting skills are a strong focus for developing encoding and fluency skills.
