Daily Oxytocin Does not Improve Social Functioning in Children with ASD

Giving children with autism spectrum disorder (ASD) regular doses of the hormone oxytocin does not appear to overcome deficits in social functioning, according to a study funded by the National Institutes of Health. 

The findings contradict earlier reports that indicated oxytocin, a hormone associated with empathy and social bonding, could alleviate the difficulties in social functioning characteristic of ASD. 

The study, believed to be the largest of its kind to date, appears in the New England Journal of Medicine, and was conducted by Linmarie Sikich, MD, of Duke University, and colleagues.

ASD is a complex neurological and developmental disorder that begins early in life and affects how a person interacts with others, communicates and learns. Many individuals with ASD have been prescribed oxytocin by their physicians. Several small studies have tested the potential of oxytocin to improve social functioning in ASD but have produced inconsistent results.

For the current study, oxytocin was administered by nasal spray every day for 24 weeks to children with ASD who are minimally or fluently verbal. Participants ranged from 3 to 17 years old. Of those completing the study, 139 received oxytocin and 138 received a placebo. During the study, participants’ caregivers rated them on a questionnaire measuring irritability, social withdrawal and other behaviors associated with ASD. When the participants completed the trial, the differences between the two groups’ initial score and last score did not differ significantly. The researchers concluded that the 24-week course of oxytocin did not improve social interaction or other measures of social function related to ASD.
