The terminology surrounding neurodiversity is a topic of considerable debate, with varying perspectives on how differences like autism, ADHD, and dyslexia are described. Central to this debate is the difference between the medical model and the social model. The medical model tends to use terms such as disorder or deficit, viewing neurological differences primarily as conditions needing treatment or correction. In contrast, the social model, embraced by the neurodiversity movement, sees these differences as natural variations in human neurology, focusing on inclusivity and societal accommodation rather than cure.
This divide extends into language preferences, where terms like autistic person (identity-first language) are preferred by many neurodivergent individuals as a means to emphasise their identity, whereas others, particularly some parents and clinicians, might use person with autism (person-first language) to separate the individual from the difference. Such preferences are deeply personal and can vary widely even within neurodivergent communities.
Additionally, some professionals and advocates continue to use terms like high-functioning and low-functioning to describe support needs, though these labels are increasingly viewed as narrow, reductive and misleading. The use of neurodiversity-related terminology reflects broader societal tensions around acceptance, stigma, and medicalisation.
