Study: Baby's Gaze May Signal Autism

When and how long a baby looks at other people’s eyes offers the earliest behavioral sign to date of whether a child is likely to develop autism, scientists are reporting.

In a study published Wednesday, researchers using eye-tracking technology found that children who were found to have autism at age 3 looked less at people’s eyes when they were babies than children who did not develop autism. But contrary to what the researchers expected, the difference was not apparent at birth. It emerged in the next few months and autism experts said that might suggest a window during which the progression toward autism can be halted or slowed.

Baby's Poor Head and Neck Control Could Provide Autism Clue

Early research suggests that if a 6-month old baby has "head lag," or weak head and neck control, it may be an early sign of autism or another language/social developmental delay.

The test is simple – babies who are lying on the floor are pulled up into a sitting position. If the baby's head is not moving forward as you pull the baby up, it's a sign of weak head and neck control.
Researchers already know that head lag could be an early sign that a child's nervous system is not developing correctly. They've seen this in children with cerebral palsy and preterm infants, for example. But so far it had not been documented in children with autism.
