Signs & Symptoms

A child’s risk of autism is slightly elevated if a parent or sibling has asthma or an autoimmune disease.

For autistic people, social difficulties may contribute to troubles with daily living — from brushing teeth to taking a bus.

Australia has become the latest country to establish guidelines for diagnosing autism, but getting clinicians to comply may be difficult.

The brains of autistic children show few differences from those of children with attention deficit hyperactivity disorder, or even of controls.

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

Motor problems in autistic infants may parallel those in infants with other developmental conditions.
