A split in the spectrum? The ongoing battle to define autism

When the Label Expands: England’s Autism Diagnosis Surge and the Fight Over Who Counts

Constantvpn.com – A government-commissioned independent review examining the sharp rise in diagnoses of neurodivergent conditions — including autism and ADHD — alongside a steep climb in reported poor mental health is expected to be published in the coming weeks. Its findings will land in a landscape already fractured by a bitter dispute over whether the autism label has stretched beyond its useful boundaries, or whether it has finally begun reaching the people who need it most.

The numbers behind the controversy are stark. In England, the count of adults and children carrying an Autism Spectrum Disorder (ASD) diagnosis on their GP record jumped from just over 700,000 three years ago to roughly 1.1 million today. The National Autistic Society points to evidence of significant underdiagnosis, especially among women and older adults who were overlooked by earlier, narrower diagnostic criteria. Yet the very same surge has prompted a vocal minority of researchers to ask whether some of those new diagnoses are, in fact, errors.

The Voice That Split the Community

At the centre of that minority sits Professor Dame Uta Frith, an 85-year-old cognitive scientist whose work on autism stretches back to the 1960s. She has argued that the autistic spectrum has effectively collapsed because the people now included under it have such radically different needs that the shared label obscures more than it clarifies. Her concern is not abstract: she worries that autistic individuals who require intensive, ongoing support are being crowded out of services and research attention by a flood of milder presentations.

“In my worst moments, I think it’s a great number, but in my best moments, I think it is a small number.”

That was Frith’s measured response when pressed on how many people she believes have been wrongly told they are autistic. She stopped short of giving a figure, but her framing — misdiagnosis rather than overdiagnosis — has drawn sharp criticism from fellow researchers, charities, and autistic advocates who call her position “dangerous” and “misinformation,” arguing it pits autistic people against one another and threatens hard-won identity and rights.

A History Written in Shifting Definitions

The question of what autism actually is has never had a single, stable answer. The term was coined in 1911 to describe what was then understood as a symptom of childhood schizophrenia — excessive fantasies and hallucinations. By 1943, clinicians were using it to label children displaying what one observer called “fascinating peculiarities,” children who seemed disinterested in the world around them. Through the 1960s, estimates placed childhood autism at roughly 0.04% of the population, and most affected children also carried intellectual disabilities.

The early 1980s brought a conceptual rupture. Researchers began embracing the notion of an autism spectrum, arguing that autistic individuals could possess average or even exceptionally high intelligence. This broader category was initially called Asperger’s Syndrome, named after a little-known Austrian paper from the 1940s. The term has since been retired. In 2013, ASD became the single official diagnostic umbrella for all autistic people, folding together presentations that range from non-verbal individuals requiring round-the-clock care to high-functioning adults who navigate professional life with relative independence.

The Human Cost Beneath the Debate

Behind the statistics and the academic argument sits a person like James Fitzpatrick, a 34-year-old man who does not speak, lives with a learning disability, and requires constant daily care. His existence is the reason Frith says she feels “almost a duty” to speak: she believes autistic people with intellectual disabilities are being ignored both in research and in public awareness. Approximately one-third of autistic people have intellectual disabilities, yet a 2019 study found they constituted only about 6% of participants in autism research.

The backlash against Frith has been personal as well as professional. Social media has alternately hailed her as a “pioneer” and a “brilliant” figure and branded her a “traitor” and an “out-of-touch grifter” who is “past her sell-by date.” During one interview, she received an email — hate mail — telling her she would have blood on her hands, laced with expletives. She chose to continue speaking.

“Some people would say it would be better for me to stop. But I want to get at the truth.”

She hesitated for years before voicing her concerns, partly because, in her own words, she “really, really” did not want to hurt people. That hesitation, and the ferocity of the response it eventually provoked, underscore how deeply the autism label is woven into identity, access to services, and political advocacy.

What Comes Next

Whatever the pending government review concludes, it is unlikely to settle a question that has been contested for over a century: where the boundaries of autism lie, and whether a single diagnostic category can serve people whose needs span the full range of human cognition and communication. For advocates, the stakes are concrete — funding, support services, inclusion in research, and the right to be seen. For scientists, the stakes are methodological — whether a spectrum label helps or hinders targeted intervention. And for individuals like Fitzpatrick, the stakes are simply whether the system will find them, support them, and not lose them in the noise of a debate about labels.
