Studies of infants at risk for autism have not yielded a test to predict who will eventually be diagnosed. But they have transformed our understanding of the condition.
The tendency of people with autism to not make eye contact is rooted in genetics, suggests a study of identical and fraternal twins.
The reasons some people with autism don’t make eye contact may differ between childhood and adulthood.
A camera embedded in a pair of eyeglasses can reliably gauge a child’s tendency to look another person in the eye.
The pupils of preschoolers with autism are slow to constrict in response to light, a phenomenon that may serve as an early marker of autism risk.
Toddlers with autism are oblivious to the social information in the eyes, but don’t actively avoid meeting another person’s gaze.
People with autism show atypical patterns of gaze even when they are explicitly asked to look at another person’s eyes.
Children with autism may be so consumed by their interests that they don’t pay attention to social information.
Childhood disintegrative disorder, a rare and severe condition, rapidly melts away a child’s abilities. A new theory proposes that this little-known condition turns back the developmental clock.
