Study: Signs of autism may show up as early as first month

continued She also cautions that babies looking at videos of their mothers are not the same as the actual stimuli created by a mom interacting with her baby. "Are these babies less interested in eyes because mouths are more interesting to look at and more attractive because there's more movements? To me that's one of the big questions," says Stone.
Dr. Max Wiznitzer, a pediatric neurologist and autism specialist at the Rainbow and Babies Children's Hospital in Cleveland, Ohio, says this new study is a continuation of previous work in babies. He says this research makes sense to him. "There's a decrease in the amount of attention to eyes as an early marker of social behavior (think of it as a primitive level of socialization)." Wiznitzer suggests the failure to establish these early social skills has ramifications later as "social behavior shifts into more sophisticated patterns."
If this research bears out, then maybe at some point a pediatric practice could track eye movements as one way to diagnose a child with autism, says Stone. "But we're really, really far away from that."
Wiznitzer says this may explain why the autism symptoms may be more apparent at 18 to 24 months, "even though 'subclinical' onset was months earlier." He also suggests these study results may offer another explanation why the measles, mumps and rubella vaccine, which isn't administered until a baby is at least 12 months old, cannot be blamed for causing autism.
Everyone agrees this research needs to be replicated in bigger studies with more children, Wiznitzer says. "The authors are correct that a replication study using a larger number (of children) is necessary. Before that time, I would not devote extensive resources towards assessing eye attention in infants or designing major intervention programs."
Jones says, "what we really want to do is create growth charts for social behavior, just like we have growth charts for charting a child's height and weight." He says these those are the kind of tools that pediatricians need and parents are looking for.
