The Channel 4 documentary The Great ADHD Myth? has sparked a national conversation, and it’s a heated one. For some, it was a much needed balance to the dominant narrative, while for others it was a biased and dangerous polemic. One of the contributors to the Channel 4 programme, Child and Adolescent Psychiatrist Dr Sami Timimi, argued in his book that the onus should be on those making claims about ADHD having a neurobiological cause to provide robust supporting evidence for such claims. The evidence often cited, he argues, is often overstretched and misinterpreted. Is he right? In this episode, we grapple with some of these issues. Naomi and I consider whether the documentary could have been framed differently, how diagnostic thresholds have changed and what this means for the research, the evidence behind claims that ADHD is a brain-based condition, how we talk about ADHD, and why all this matters. Here are some links to research and other sources referred to in the episode. Here is a link to webpage for Cambridge University’s Centre for Attention, Learning and Memory (CALM), and an ACAMH (Association for Child and Adolescent Mental Health) interview with a representative from CALM summarising their research as having “so far revealed that behavioural problems, patterns of cognitive difficulties and neural profiles do not align with specific diagnoses”. There’s also this ACAMH paper’s podcast. Naomi spoke about this NYT article, and the RDoC and HiTOP research. This is the 2025 meta-analysis on brain imaging research we discussed. And for the clinical applications, journal article discussing differences between the ICD-11 and DSM-5 diagnostic criteria for ADHD, and posing the question, amongst other dilemmas and uncertainties- “do we threshold impairment against the average peer or the hypothetical potential of the individual?”. Episode of the podcast series Navigating Neuropsychology examining a detailed case study of a young woman, described as being extremely bright, and therefore whose “areas of personal weakness”, which were not considered to be low for her age group, contributed to her ADHD diagnostic decision. This episode offers a detailed exploration of how diagnosticians might consider differential diagnosis, and the uncertainty often involved with diagnostic assessments, but also shows how such uncertainty can quickly become lost following assessment, as seen in the title of the episode where the clinical case is introduced as a young adult with type 1 diabetes, mental health, and ADHD.
