3. The Science

What’s the evidence that there’s been a rise not just in diagnosis, but in autism itself?

We’ve heard that the exponential trend in autism diagnosis can be explained in large part, at least, by a widening definition and the diagnosis of groups - like women - who were previously missed. But could the amount of underlying autism also be rising? And if so, why? Professor Francesca Happé explains the role of genetics, environmental factors, and vaccine scares. And Ginny Russell, author of The Rise of Autism, talks through her research into the plausibility of various causes that people claim are behind a real rise in autism.
