Autism symptoms aided by 'love' hormone: study
Last Updated: Tuesday, February 16, 2010 | 3:55 PM ET Comments0Recommend10CBC News
A hormone associated with emotional bonding promotes social behaviour in adults with autism, French researchers say.
Scientists at the Center of Cognitive Neuroscience in Lyon found that patients who inhaled the hormone oxytocin paid more attention to pictures of faces and were more likely to notice social cues when playing a game.
In the small study, Angela Sirigu and colleagues gave the hormone to 13 patients with Asperger's syndrome, considered to be a high-functioning autism spectrum disorder.
They then observed those patients and an equal number of other patients who didn't receive the treatment playing a virtual ball-passing game.
In another experiment, the researchers measured the patients' attentiveness to emotional expressions on pictures of human faces.
The patients who received the hormone showed more attention to the visual cues in the pictures of faces, and were more likely to understand the social cues in the game.
Sirigu said the study, published this week in the Proceedings of the National Academy of Sciences, merits future research on the possible benefits of the hormone in promoting social behaviour.
People with classical autism are often uncommunicative, while those with Asperger's are often very bright but have problems with social interaction.
Previous research has found that some children with autism are deficient in oxytocin, sometimes called the "love hormone."

Oxytocin is best known for its actions in prompting childbirth and lactation, but it is also produced throughout life. Previous research has suggested roles for the hormone in emotional regulation and social behaviors. One study found that inhaled oxytocin made adults more trusting of others in a game situation.
Some investigators have also found that oxytocin levels are depressed in autistic individuals. One of the hallmark symptoms of autism is social withdrawal and impaired responsiveness to other people, marked by such behaviors as greatly diminished eye contact.
Participants in the study were 17 to 39 years old, with an average age of 26. Ten had received clinical diagnoses of Asperger's syndrome, and three were considered to have high-functioning autism.
Patients received either a nasal spray containing oxytocin or an ineffective dummy nasal spray and participated in behavioral experiments 50 minutes later. In the video ball game, participants played a game of toss-and-catch with three cartoon characters whose interaction with the player could vary. Initially, each character sent the ball to the player 33 percent of the time, passing it between themselves the rest of the time. After awhile, the percentages changed such that one character would send the player the ball 70 percent of the time, the second sent 30 percent of balls to the player, and the third sent just 10 percent of balls to the player. The player was promised a payment for each ball he or she received.
