Channel 4 is wading into one of the fiercest medialkrishi debates with The Great ADHD Myth?, a provocative 60-minute documentary hosted by NHS psychiatrist Dr. Max Pemberton, airing August 18.
With ADHD referrals soaring 200% between 2020 and 2025, Pemberton questions whether ADHD is fundamentally a neurodevelopmental disorder, a social construct, or something shaped by both biology and modern life.
