The so-called trust hormone, oxytocin, may not improve the symptoms of children with autism, a large study led by researchers at the University of New South Wales (UNSW) has found.
Professor Mark Dadds, of the UNSW School of Psychology, says previous research suggested that oxytocin — a hormone with powerful effects on brain activity linked to the formation of social bonds — could have benefits for children with the disorder.
“Many parents of children with autism are already obtaining and using oxytocin nasal spray with their child, and clinical trials of the spray’s effects are underway all over the world. Oxytocin has been touted as a possible new treatment, but its effects may be limited,” Professor Dadds says.
