Which tenet is included in the current IDA definition of dyslexia?

Dyslexia is recognized as having a neurobiological origin, which means that it is fundamentally linked to the brain's structure and function. This understanding helps underscore that dyslexia is not simply a behavioral or environmental issue but is rooted in the neurological processes involved in language and reading. This recognition has significant implications for how dyslexia is approached in educational settings, informing strategies that are based on the understanding that the condition arises from brain differences that influence language processing abilities. By recognizing dyslexia as neurobiological in origin, educators and practitioners are better equipped to provide evidence-based interventions tailored to the needs of individuals with dyslexia.
