Oxytocin, a hormone often referred to as the "cuddle chemical" for its role in helping to foster intimate relationships—particularly between mothers and their newborns—may help people with autism to read and react to social cues, according to the preliminary results of a small study published in the Proceedings of the National Academy of Sciences. Individuals with autism spectrum disorders often have trouble engaging and interacting in social situations, frequently avoiding eye contact, for example, and previous research has also shown that people who are autistic often have lower levels of the hormone oxytocin. In this recent study, researchers from France's Center of Cognitive Neuroscience used nasal inhalers to give oxytocin to 13 individuals with high-functioning autism or Asperger's syndrome. Afterwards, the researchers examined the study participants' reactions to social stimuli. They found that, after the oxytocin, the subjects showed significant improvement on social tasks—including making more eye contact when shown pictures of faces, and responding to other players in a ball tossing game. 
 
 Oxytocin, sometimes referred to as the "love hormone", is one powerful chemical: during physical intimacy, it increases for both men and women; it acts as a hormone to help induce labor and lactation in mothers; and it also serves as a nuerotransmitter in the brain—research suggests that it influences everything from our ability to fall in love, to our tendency toward monogamous relationships and ability to trust others. Should these initial findings be confirmed, they may suggest a potential therapeutic use of oxytocin for individuals with autism spectrum disorders. What's more, it could even increase opportunities for early intervention for children diagnosed with autism. As Angela Sirigu, lead author of the study, told the Washington Post, "It's possible it can become a cure, if it's given early when the problems are detected in the little kids... We can change the way these patients interact with people from childhood." ||||| A nasal spray containing a hormone that is known to make women more maternal and men less shy apparently can help those with autism make eye contact and interact better with others, according to a provocative study released Monday. 
 
 The study, involving 13 adults with either a high-functioning form of autism or Asperger syndrome, a mild form of the disorder, found that when the subjects inhaled the hormone oxytocin, they scored significantly better on a test that involved recognizing faces and performed much better in a game that involved tossing a ball with others. 
 
 Although more research is needed to confirm and explore the findings, the results are the latest in a growing body of evidence indicating that the hormone could lead to ways to help people with the often devastating brain disorder function better. 
 
 "This is the first study that looked at whether oxytocin has an effect on social behavior, which is a major deficit in autism," said Angela Sirigu, who directs the National Center for Scientific Research in France and led the study, published online by the Proceedings of the National Academy of Sciences. "It looks like it could be very helpful." 
 
 Researchers who were not involved in the study praised the work, saying the findings were promising and could lead to the first effective treatment for the central problems affecting people with autism. 
 
 "I think it's going to be a very exciting finding for a lot of people," said Alex Martin, chief of cognitive neuropsychology at the National Institute of Mental Health. 
 
 Because oxytocin does not last long in the body and produces its effects for a relatively brief period, some experts said the findings were more likely to encourage drug companies to develop alternative substances that had the same benefits. 
 
 "This paper suggests that's worth doing," said Thomas R. Insel, director of the institute. "It adds another brick in the wall that suggests there may be an opportunity to develop treatment for one of the core symptoms of autism. That's been the brass ring." 
 
 But Sirigu was among those who said the finding should encourage more research on the potential benefits of oxytocin itself, especially for children. Administering the hormone soon after a child's autism is diagnosed might help him or her develop more normally, she said. 
 
 "It's possible it can become a cure, if it's given early when the problems are detected in the little kids," Sirigu said. "We can change the way these patients interact with people from childhood." 
 
 Because previous research has indicated that some people with autism might have abnormally low levels of oxytocin, conducting tests to identify those people and administering them the hormone might help as well, said Karen Parker, an assistant professor of psychiatry at Stanford University School of Medicine. 
 
 "If you can find someone who appears to have deficits in oxytocin biology, giving them what you might argue would be replacement oxytocin may be helpful," Parker said. 
 
 Autism is a baffling disorder that can cause a variety of symptoms, including speech and learning problems and profound, disabling difficulties understanding emotions and social cues when interacting with people. The number of children found to have autism has been increasing for reasons that remain mysterious. 
 
 Oxytocin is produced naturally in the bodies of humans and animals. It plays a key role in social interaction, promoting maternal behavior and monogamy in animals. The hormone also heightens social sensitivity, social awareness, generosity and trust in people. 
 
 Previous U.S. studies found that people with autism who received the hormone intravenously were less likely to engage in repetitive behavior that is another hallmark of autism and were more likely to be able to identify emotions in voices. Another study being published in the journal Biological Psychiatry found that 16 autistic males in Australia ages 12 to 19 who received the hormone through a nasal spray were better able to recognize other people's facial expressions. 
 
 "All the data seem to suggest that manipulating the oxytocin system has a powerful effect on the core symptoms of autism," said Eric Hollander, director of the compulsive, impulsive and autism spectrum disorders program at the Montefiore Medical Center in New York. 
 
 While cautioning that more research is needed on children and additional patients to make sure oxytocin is safe and effective, advocates for families with children with autism welcomed the findings. Oxytocin has been in use for several years as an "alternative" therapy for autism. 
 
 "Many families are using it with success and reporting improvement," said Wendy Fournier, president of the National Autism Association. "Getting double-blind clinical studies like this one published helps to bring credibility to parental reports." 
 
 "We need to be mindful of the fact that the majority of human studies of oxytocin have been conducted using adults, including this study, and only one paper has included individuals between the ages of 12 and 18. We have to be careful about the safety and efficacy of oxytocin on pediatric populations," said Clara Lajonchere, vice president of clinical programs for Autism Speaks.
– The hormone oxytocin may improve the social skills of people with high-functioning autism. In a new study, patients who received doses of it in a nasal spray were better able to recognize faces and interact with others in a game. In short, the so-called "love chemical" seems to help those with autism and Asperger's syndrome better able to pick up on social cues, reports Time. The researchers hope oxytocin therapy could become a powerful treatment therapy and perhaps even correct social deficits before they form. "It's possible it can become a cure, if it's given early when the problems are detected in the little kids," the lead scientist tells the Washington Post. "We can change the way these patients interact with people from childhood."
