What Is Dyslexia?

What is Dyslexia? Kelli Sandman-Hurley, Dyslexia Training Institute

Dyslexia is a specific learning disability that is neurobiological in origin. It is characterized by difficulties with accurate and/or fluent work 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 classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth in vocabulary and background knowledge.

In simpler terms…
Dyslexia is an inherited condition that makes it extremely difficult to read, write, and spell in your native language—despite at least average intelligence. Bright Solutions for Dyslexia

In Ontario, dyslexia is most often referred to as a Learning Disability (LD) or in the context of a psychological assessment, a Specific Learning Disorder (SLD). Dyslexia is one type of LD and is considered the most common and well-recognized sub-type of SLD. Approximately 80% of those identified as having an LD are dyslexic.

Decoding Dyslexia Ontario believes it is important to move beyond the broad category of LD and be specific in identifying dyslexia so that effective, evidence-based interventions can be provided as quickly as possible to a child who struggles to learn to read because of dyslexia.
