Defining Dyslexia

Dyslexia is a brain-based learning disability that specifically impairs a person’s ability to read. For individuals with dyslexia, specific portions of the brain typically associated with important reading processes may not function in the same ways that they do in individuals without dyslexia. Individuals with dyslexia often have difficulty with phonological processing, spelling, or rapid visual-verbal responding. Importantly, dyslexia is related to reading difficulties, not difficulties that arise from intellectual functioning.
