A Channel 4 documentary, "The Great ADHD Myth?", presented by consultant psychiatrist and journalist Dr Max Pemberton, concluded that ADHD is a "social construct" rather than a neurodevelopmental disorder. Within days, the story became less about the documentary's claims and more about how it made them.
The featured expert says she was misrepresented
Professor Katya Rubia, professor of cognitive neuroscience at King's College London and one of the most cited ADHD neuroimaging researchers in the world, was interviewed in the documentary itself. She has publicly stated that her hours-long interview was "cherry-picked, truncated and presented out of context" to fit the programme's narrative that ADHD does not exist and has no brain basis. She says she agreed to take part precisely because she knew the film's angle and wanted to provide the alternative view. For fairness: Channel 4 responded that it is "satisfied that Katya Rubia's contribution has been edited fairly" and that her consent was informed.
The wider expert reaction was unanimous
The UK's Science Media Centre gathered reactions from researchers across institutions: Cardiff University, the Royal College of Psychiatrists (its president, no less), Brighton and Sussex Medical School, King's College London, Bournemouth University and more. Not one defended the programme. Their core points: ADHD shows heritability around 70 to 80%, three decades of consistent neuroimaging findings including the large ENIGMA brain-volume analyses, and a crucial distinction the documentary blurred: saying a diagnostic threshold is "constructed" is very different from saying the underlying condition is not real. Every diagnostic cutoff in medicine is constructed. The difficulties it describes are not.
The on-screen "experiment" that proves nothing
The documentary's emotional centerpiece followed Mason, a 10-year-old taken off his ADHD medication during filming, whose mother said he got his "sparkle" back. What viewers may not have registered: the medication stop came alongside roughly six simultaneous lifestyle changes, diet overhaul, screens removed, more one-on-one family attention, and more. As the experts pointed out, that is a single-child anecdote with expectancy and observer effects, in which nothing can be attributed to any one change. And there is a detail that undercuts the film's own thesis: by week five, his teacher documented him becoming "more disruptive, more talkative, more fidgety", a pattern entirely consistent with medication wearing off a real condition.
What is legitimate in the debate
To be fair to the underlying questions: rising diagnosis rates, assessment quality, and how readily medication is prescribed are real, worthwhile debates that researchers themselves engage in constantly. But there is a large gap between "we should examine diagnosis and treatment practices" and "the condition does not exist". The evidence, genetic, neuroimaging, longitudinal, sits firmly on one side of that gap, and the very expert the documentary chose to feature says her words were bent toward the other.
Bottom line
When a documentary's conclusion requires cherry-picking its own expert, the conclusion is doing the work the evidence would not. If you keep seeing "ADHD is not real" content, the response is not outrage, it is sourcing: the heritability data, the imaging data, and now the on-record statement of the scientist the film itself quoted.
If you want to explore your own neurotype, our free ADHD screening is a starting point for self-understanding, not a diagnosis.
