Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.

Depression may show up in children with autism in an unusual way — most commonly as insomnia and restlessness.

Heightened sensory perception in toddlers with autism may predict sleep problems at around age 7.

Scientists have created five monkey clones, all carrying an edit to a specific gene.

About one in three autistic people in the United Kingdom is prescribed drugs designed to alter brain function.

Children with autism are more likely to have both sleep problems and constipation than would be expected based on the prevalence of each of those conditions.
