Two unrelated studies have identified new ways to augment behavioral therapy for the treatment of autism. One, published in the journal Translational Psychiatry, suggests functional magnetic resonance imaging (fMRI) can identify which children will respond best to Pivotal Response Treatment (PRT). A second study, published in Scientific Reports, found oxytocin could enhance social motivation by supporting neural networks associated with rewarding social behavior.
Using fMRI to Predict Autism Treatment Effectiveness
Pivotal Response Treatment targets areas of development, such as motivation and social skills, rather than single behaviors. PRT uses rewards, encourages child-directed learning, and endorses natural reinforcement. The program works for about 60% of children with autism, but it can be expensive and time-consuming.
Researchers used functional magnetic resonance imaging (fMRI) screenings on the brains of 20 children with autism. The children were all in good health, with no significant history of brain injuries. Each child underwent 16 weeks of PRT.emotional information revealed children with more activity in these regions were more likely to experience improvements with PRT. Identifying children most likely to respond to this treatment may prompt future research into how to better prepare children who are less likely to respond to PRT.
Oxytocin to Support Social Skills in Children with Autism
For the second study, researchers explored how oxytocin affects the behavior of children with autism. Oxytocin is a hormone involved in bonding and social behavior.
Researchers conducted two separate trials on 21 children with autism, though some children were eventually excluded from the study. One trial ultimately involved 14 children and another involved 16. Almost all participants were boys. Using a double-blind, placebo-controlled model, researchers administered oxytocin via a nasal spray.
After the oxytocin or placebo dose, children participated in various social experiences. Children who received oxytocin responded better to social cues, but only when the cues were positive, such as smiles or laughing. Brain scans revealed the oxytocin helped support neural networks associated with social processing. Even with these promising results, the researchers do not suggest this oxytocin method as a main treatment for autism. Instead, it could complement other behavioral treatment methods.
The sample sizes of both studies were small, so the results are preliminary. Further research could strengthen the results and perhaps point to more effective treatments for autism.
