When Halloween “Hyper” Meets ADHD: What a New Study Reveals About Overdiagnosis

Every October 31st, kids go wild - costumes, sugar, excitement - but what if that same energy is quietly shaping ADHD diagnoses? In this Doctor’s Desk episode, Justin and Kylie unpack a fascinating new study showing a 14% spike in ADHD diagnoses on Halloween day. They explore what this says about subjectivity in diagnosis, the risks of overlabelling kids, and how our environments - not just our children - might need rethinking. KEY POINTS: A new Harvard study found ADHD diagnoses rise 14% on Halloween compared to surrounding days. ADHD remains a subjective diagnosis — there’s no blood test or scan to confirm it. Why environment and maturity often explain behaviours mistaken for “disorder.” The real risks of misdiagnosis — medication, labelling, and self-perception. Why it’s time to look at what’s happening around kids, not just within them. QUOTE OF THE EPISODE: “There isn’t anything wrong with her — she just doesn’t fit the mould of what we consider normal.” RESOURCES MENTIONED: Study: Halloween, ADHD, and Subjectivity in Medical Diagnosis (National Bureau of Economic Research) Searching for Normal by Sami Timimi The Parenting Revolution by Justin Coulson ACTION STEPS FOR PARENTS: Before seeking a diagnosis, consider context — sleep, stress, diet, and school environment. Avoid rushing to label; focus on understanding and supporting your child’s unique needs. Ask questions — about treatment pathways, environment, and alternative perspectives. Create calmer spaces where kids can regulate, play, and thrive. See omnystudio.com/listener for privacy information.
