Signs & Symptoms

Children with dup15q syndrome may have telltale patterns of brain activity during sleep and get less non-REM sleep than neurotypical children do.

Connections between the cerebellum and brain networks do not seem to contribute substantially to the emergence of autism traits.

People with autism or autism traits may be especially vulnerable to brain aging and cognitive decline, two studies suggest.

Young male rats can recognize rats they’ve recently met, whereas young females treat new acquaintances like strangers, research shows.

During conversations, girls with autism use “we,” “they” and other plural personal pronouns differently than autistic boys do.

Autistic people’s skill at managing the demands of daily life decline after they leave high school, according to a new study. But those who maintain more abilities are more likely to pursue further education than those who don’t.

People with autism who carry DNA variants in the same protein-coding region of a gene have more similar cognitive abilities and behaviors than those who carry mutations in different regions of the same gene.

Some social behaviors associated with autism are heritable, but the extent to which genes and the environment influence these behaviors changes as a child grows.
