A new study from Yale University is the first study to evaluate the impact of oxytocin on brain function in children with autism spectrum disorders, finding that a single spray of oxytocin improves brain function in children with autism.
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 December 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 adjunct assistant professor, 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 nasal spray during a task involving social judgments. Oxytocin is a 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 brain regions 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 autism spectrum disorders,” Gordon added.
Other authors on the study include Brent C. Vander Wyk, Randi H. Bennett, Cara Cordeaux Zagoory-Sharon, James F. Leckman, and Ruth Feldman.
The study was funded by a Harris Family Professorship to Pelphrey; a Lee Foundation Postdoctoral Award to Gordon; and a grant from the Binational Science Foundation to Feldman, Pelphrey, Gordon, and Leckman.

The NYT article went into more detail and the best effect is on the mild cases, the other having almost no effect and the article cautioned against larger doses as lab studies show the opposite as the animals became even more aggressive.
It is true that autistic children responds more for non-social objects more than social figures and faces. This experiment exposes the effect of Oxytocin spray to enhance their attention of social figures withdrawing their attention from non-social objects. If the continued use of OT spray with the children can improve their behavior it is well and good. Thank You.
Essentially speaking, doctors diagnose autism based on officially issued guidelines, although these parameters can vary somewhat from one country to the next. Patients will usually be assessed during an interview, and more often than not, parents and even teachers might be asked to complete a questionnaire relating to a child’s behavior.
