In the past people who have had high-functioning autism were considered by others to have Asperger’s syndrome. Recently, American Psychiac Association members have stated that they prefer that those with a diagnosis of Asperger’s syndrome be classified as instead having an autism spectrum disorder.
Prof. Francesca Happe of the Institute of Psychiatry in London, England, said “The Asperger’s distinction is based on early language delay, but many people come in as adults and have difficulty reporting this reliably. We have known for years that autism is a spectrum, which is enormously heterogeneous. … There is no good basis to distinguish Asperger’s from high-functioning autism. The distinction doesn’t make scientific sense.”
