"People have been through a cultural change in understanding neurodiversity and autism has become a favourite of fiction and films," says Frith. "But it"s focussed on very few features, in particular positive features." The kind of autism most often being presented in popular media would be categorised as mild, she says. Also, on-screen characters with autism are often portrayed as being intellectually gifted. The danger, she says, is that this misses out those who need more support.
