Diagnosing autism is an evolving science but a crucial first step to understanding the disorder.

Harmful mutations in a gene that regulates the chemical environment outside of neurons are associated with both autism and epilepsy, according to a study published 31 March in Neurobiology of Disease.
Individuals with autism have multiple mutations in a pathway that functions in the mitochondria, the energy center of the cell, according to a study published 27 April in the European Journal of Human Genetics. They also have higher-than-average numbers of variants in pathways involved in metabolism, gene expression and the regulation of cell division.
Autism is diagnosed based on the severity and variety of its symptoms. This makes it very difficult to diagnose and easy to confuse with other disorders, such as language delay and intellectual disability, cautions Isabelle Rapin.
Individuals with intellectual disability are more likely than controls to have harmful mutations in autism candidate genes, according to a study published 11 March in the American Journal of Human Genetics.
Teenage boys with Asperger syndrome with higher-than-average scores on tests of abstract reasoning fare worse than controls on short-term memory and ability to filter out distractions.
