What this study means for families
This study looked at brain scans of 38 people with autism before and after 14 weeks of social skills training. The training changed how different parts of the brain connect with each other - like improving the brain's internal communication system. People who received training also showed better social skills on questionnaires. While researchers couldn't prove the brain changes directly caused the social improvements, this suggests that social skills training might actually rewire the brain in helpful ways.

Research summary
This controlled study examined brain changes in 38 individuals with autism spectrum disorder (aged 12-30) following 14 weeks of social skills training. Using advanced brain imaging techniques, researchers found that social skills training led to measurable changes in white matter connectivity - the brain's communication pathways. The training group showed four significant changes in brain connections, with three increasing and one decreasing. Participants also showed improved social responsiveness scores.
However, the study couldn't establish a direct link between brain changes and behavioral improvements, likely due to the small sample size. These findings provide early evidence that social skills training may physically reshape brain networks in autism.

Clinical implications
Social skills training appears to induce measurable brain changes alongside behavioral improvements. While the relationship between neural and behavioral changes requires further investigation, these findings support the neurobiological basis for social skills interventions and may inform development of more targeted autism therapies.

Original abstract
Social skills training (SST) has demonstrated efficacy in improving social deficits in individuals with autism spectrum disorder (ASD), but the underlying neural mechanisms remain unclear. This study investigated alterations in whole-brain white matter network topology after SST in ASD individuals and explored potential correlation with improvements in social interaction deficits. 38 ASD patients aged 12 - 30 years were recruited, including 19 who completed magnetic resonance imaging (MRI) scans and social responsiveness scale (SRS) assessments at both baseline and the endpoint of a 14-week SST (training group) and 19 age-, sex-, and IQ-matched patients who underwent MRI scans and SRS assessment at the same time points but did not receive SST (control group). White matter connectivity matrices were constructed using diffusion tensor imaging (DTI), and graph theory analysis was used to assess global and nodal network properties. Paired t-tests and independent-samples t-tests were used for within- and between-group comparisons, respectively.
Pearson's partial correlation was used to examine associations between network changes and SRS scores changes. After SST, four edges showed significant changes in white matter connectivity (FDR-corrected), with three increased and one decreased in the training group. Changes in nodal betweenness were also observed. While SRS scores significantly decreased in the training group, no significant correlations were found between neuroimaging changes and behavioral improvements, possibly due to the limited sample size.
These findings suggest that SST may reshape white matter network, offering insights into its neural mechanisms and informing novel ASD intervention strategies.
