Signs & Symptoms

Children with highly folded and curved brains in utero tend to show autism-linked behaviors at 18 months of age, according to a longitudinal brain-imaging study.

So-called ‘baby sibs’ watch adults’ faces just as much as children without autistic siblings do, but they don’t understand spoken language as well.

A test of binocular rivalry may distinguish between autism subtypes and help researchers screen the efficacy of certain drugs.

More autistic women and girls report daily pain than do men and boys with the condition.

Autistic people with at least one sibling make greater gains in adaptive functioning than their only-child counterparts do.

Deleting the autism-linked gene CHD8 from specific cells in the cerebellum, a brain region important for movement, leads to motor deficits but does not alter social behaviors in mice.

A mobile phone app that tracks a toddler’s gaze as she watches short videos can distinguish between children who later receive an autism diagnosis and those who do not according to a new study.

Autistic children are up to four times as likely as their non-autistic peers to have digestive problems, and several small studies show they may also have atypical microbial communities living in their guts.
