title: Autism spectrum disorder: prevalence and cause may be bound together.
abstract: Autism has been in the forefront of science and public concern because of reported increases in its prevalence. Changing diagnostic practice and improved identification explain some of this rise, but there may also be a true increase. Aetiological research needs to include environmental factors to understand the causes of autism.
