Channel 4 announces a documentary called 'The Great ADHD Myth?' Lots of people - many of them with ADHD - react angrily, arguing the show's title adds to the stigma and distrust around diagnosing the disorder. The documentary aims to explore the causes of ADHD - some people think that's a conversation we urgently need to have, given growing rates of diagnosis, lengthening waiting lists, and rising benefit claims related to the disorder. We find out how ADHD is defined and diagnosed, ask whether there is any evidence of over-diagnosis, and explore the disorder's history.
