We studied social cognition in 49 children 3 months after moderate to severe traumatic brain injury (TBI) and in 39 children with orthopedic injury (OI). Children underwent diffusion tensor imaging (DTI) and a mental attribution task showing two triangles. Mental state attributions increased when one triangle reacted to intentions of the other, but less so in the TBI than the OI group. DTI identified injury to white matter microstructure in the TBI group, but the relation of DTI to mental attributions did not differ between groups. Moderate to severe TBI produces white matter disconnections that may affect social cognitive networks.
我们对49名中重度创伤性脑损伤（TBI）患儿和39名骨科损伤（OI）患儿在受伤3个月后进行了社会认知研究。患儿接受了扩散张量成像（DTI）和一项展示两个三角形的心理归因任务。当一个三角形对另一个三角形的意图做出反应时，心理状态归因增加，但TBI组的增加幅度小于OI组。DTI显示TBI组存在白质微结构损伤，但两组中DTI与心理归因之间的关系并无差异。中重度TBI会导致白质连接中断，这可能会影响社会认知网络。
