Implications of Reduced Callosal Area for Social Skills after Severe Traumatic Brain Injury in Children

Abstract

The corpus callosum has been shown to be particularly vulnerable to the effects of traumatic brain injury (TBI) in childhood, and severe injury frequently results in a smaller corpus callosum post-injury. However, the long-term effects of TBI on the integrity of the callosum, as well as the potential functional significance of callosal injury are poorly understood. Some studies suggest the corpus callosum may be involved in social skills, which are often reduced following TBI. In this study, callosal size was investigated in 37 individuals 10 years post-childhood TBI, and its relationship with social competence was examined. The results indicate that individuals who sustain severe TBI in chi..
