John Davidson: 40 years of living with Tourette syndrome

John Davidson has been the poster boy for Tourette syndrome since 1988, when a documentary about him called ‘John’s Not Mad’ aired on BBC One. It showed the then 16-year-old from the Scottish Borders, living with explosive, often sweary tics, in a world that didn’t understand the condition. Three decades on, we’re much more aware of Tourette syndrome and that’s in no small part down to John and his campaigning. Now, a film based on his life - ‘I Swear’ - starring Maxine Peake and Robert Aramayo is about to be released.In this episode, John talks to Emma Tracey about the challenges of teenage tics, being shut in a school cupboard by a teacher so he didn’t distract the class, and the impact the physical tics are having on his joints and muscles as he gets older.
