title: Neuroimaging and social behavior in children after traumatic brain injury: findings from the Social Outcomes of Brain Injury in Kids (SOBIK) study.
abstract: BACKGROUND
  Neuroimaging studies identified either focal and/or non-specific frontotemporolimbic damage resulting from mild-complicated to severe traumatic brain injury (TBI) in a subset of 12 children 8-12 years of age who were part of the Social Outcomes of Brain Injury in Kids (SOBIK) study. The influence of identifiable damage on social behavior was examined.
  
  
  METHODS
  Magnetic resonance imaging was obtained on average 2.5 years post injury wherein cases with distinct abnormalities were selected. Various direct, performance-based measures of cognitive-social-emotional functioning were obtained along with data regarding peer relations and friendships in the classroom.
  
  
  RESULTS
  Overall, children with TBI were impaired on tasks of social-emotional processing compared to children with orthopedic injury (OI). Ten of the 12 children with TBI had multiple areas of impaired social-emotional functioning in comparison to OI controls. With regards to friendships, four of the nine children with TBI who had classroom data had no mutual friends, four also received low peer acceptance ratings, and two were perceived by peers as having high levels of rejection/victimization in the classroom.
  
  
  CONCLUSIONS
  Children with frontotemporolimbic or diffuse damage demonstrated variable social outcomes from their TBI. Results are discussed in terms of the heterogeneity of TBI-related abnormalities and their relationship to social behavior.
