A single dose of the hormone oxytocin, delivered via nasal spray, has been shown to enhance brain activity while processing social information in children with autism spectrum disorders, Yale School of Medicine researchers report in a new study published in the Dec. 2 issue of Proceedings of the National Academy of Sciences.

"This is the first study to evaluate the impact of oxytocin on brain function in children with autism spectrum disorders," said first author Ilanit Gordon, a Yale Child Study Center postdoctoral fellow, whose colleagues on the study included senior author Kevin Pelphrey, the Harris Professor in the Child Study Center, and director of the Center for Translational Developmental Neuroscience at Yale.

Gordon, Pelphrey, and their colleagues conducted a double-blind, placebo-controlled study of 17 children and adolescents with autism spectrum disorders. The participants, between the ages of 8 and 16.5, were randomly given either oxytocin spray or a placebo during a task involving social judgments. Oxytocin is naturally occurring hormone produced in the brain and throughout the body.

"We found that brain centers associated with reward and emotion recognition responded more during social tasks when children received oxytocin instead of the placebo," said Gordon. "Oxytocin temporarily normalized brain regions responsible for the social deficits seen in children with autism."

Gordon said oxytocin facilitated social attunement, a process that makes the involved in social behavior and social cognition activate more for social stimuli (such as faces) and activate less for non-social stimuli (such as cars).

"Our results are particularly important considering the urgent need for treatments to target social dysfunction in ," Gordon added.
