Neurodiversity refers to the idea that neurological differences, such as those seen in autism or ADHD, reflect normal variations in brain development. Neurodiversity is often contrasted with the “medical model,” which views conditions like autism or ADHD as disorders to prevent, treat, or cure. There is a push to move away from this idea of pathology and more toward a more nuanced perspective with variations of what is “normal.”
Who is considered 'neurodiverse'? The word neurodiversity—a portmanteau of “neurological” and “diversity”—was first coined in the 1990s by Australian social scientist Judy Singer, who is herself on the autism spectrum. It has gained significant ground in recent years, particularly among advocacy communities. The term originally referred most commonly to autism but has since come to include ADHD, dyslexia, Tourette's, synesthesia, as well as other learning and developmental differences.
