Broadcaster John Offord chats to Siena Castellon, an award-winning advocate for neurodiversity, an author, a student and the founder of the ‘Neurodiversity Celebration Week' – to talk about what being neurodivergent means to her. Siena classes herself as a ‘maths and physics nerd’ and claims her dog is the cutest dog in the world. Siena is also neurodiverse: She is autistic, dyslexic, dyspraxic and has ADHD.
