A ‘predictive coding’ theory of autism suggests that many of the condition’s hallmark traits occur when sensory input overrides expectation in the brain.

Raphael Bernier and James Mancini describe the similarities and differences between autism and attention deficit hyperactivity disorder.

Autism and attention deficit hyperactivity disorder often coincide, but the search for common biological roots has turned up conflicting evidence.

Common genetics may help forge social ties, a nonspeaking woman with autism hosts “The Late Show,” and the mix of bacteria in the gut may relate to brain structure.

A novel take on a widely used test could help clinicians assess impulsivity in people with autism.

Young children with autism sustain injuries primarily because of co-occurring attention deficit.

Eye-tracking studies cement monkeys’ promise for studying autism and related conditions.

A monkey study suggests facial recognition is not innate, a puzzle piece symbol carries negative connotations, and scientists are using a federal law to snoop on colleagues.

Transcranial treatment may bolster memory in adults with autism, inflammatory molecule may alter an emotional brain region in newborns, and examining ants could yield insights into autism

Babies with a family history of autism have heart rates that are unusually low and that respond aberrantly to speech sounds.
