Broadcaster John Offord chats to award winning author, Steve Silberman who was once haunted by the question: Why have rates of autism diagnosis increased so steeply in the past 30 years? To solve that medical mystery for his book, NeuroTribes: The Legacy of Autism and the Future of Neurodiversity, Silberman went back to the first years of autism research, where he uncovered a series of events -- some long forgotten, and others deliberately buried -- that required the history of autism to be rewritten. Neurotribes was awarded the Samuel Johnson Prize in 2015, and has received wide acclaim from both the scientific and the popular press.
