Overview
The medical model locates disability within the individual. It frames disability as a consequence of biological impairment: something wrong with the person’s body or brain that requires diagnosis, treatment, and where possible, cure. Under this model, the primary response to disability is clinical: identify the pathology, classify it, and intervene to bring the person closer to “normal” functioning.
Origins and influence
The medical model has no single originator; it reflects the broader medicalisation of human variation that accelerated during the 19th and 20th centuries. Within autism specifically, the medical model has shaped everything from the diagnostic criteria in the DSM and ICD to the dominance of deficit-focused research and behavioural interventions designed to reduce visible autistic traits.
What it does well
The medical model has real practical value. Diagnosis under a medical framework is the gateway to services, funding, and legal protections in most countries. It enables the identification of co-occurring conditions (epilepsy, gastrointestinal difficulties, mental health challenges) that require medical attention. For some autistic people, particularly those with high support needs, medical understanding of their specific neurological profile is essential to their care.
Where it falls short
The model’s central weakness is that it frames the person as the problem. When autism is understood solely as a disorder, a collection of deficits to be remediated, the logical response is to make autistic people less autistic. This has produced a long history of interventions focused on normalisation: suppressing stimming, forcing eye contact, training “appropriate” social behaviour. The costs of such approaches, including the mental health toll of masking, are now well documented.
The model also tends to homogenise. By focusing on shared diagnostic criteria, it can obscure the enormous heterogeneity within autism. A framework that treats all autistic people as having the same “disorder” struggles to account for why some autistic people thrive in environments designed for them while struggling in environments that are not.
Relationship to autism and neurodivergence
The medical model remains the dominant framework in most clinical and educational settings globally. It is not wrong to note that autism has a neurobiological basis. The problem is the inferential step from “neurobiologically different” to “disordered and in need of correction.” Critics within both the disability rights movement and the neurodiversity community argue that this step reflects social values about what counts as “normal,” not objective scientific conclusions (Chapman, 2021; Dwyer, 2022).
