目的虽然中度或重度创伤性脑损伤 (TBI) 相关的意识丧失被认为会干扰 TBI 事件的编码，但人们对轻度 TBI (mTBI) 的影响知之甚少，轻度 TBI 通常只涉及短暂的意识破坏。方法 曾经历过爆炸的阿富汗和伊拉克战争退伍军人被要求回忆爆炸事件。根据爆炸是否与可能的 mTBI (n= 50) 或不相关 (n= 25) 对参与者进行分层。使用叙事连贯性编码方案（Reese 等人，2011）对叙事进行组织结构（即连贯性）评分，并使用自传访谈编码程序（Levine 等人，2002）对情景回忆进行评分。结果与非 TBI 组相比，mTBI 组的叙述不太连贯，但包含更多的情景细节。结论这些结果表明，mTBI 干扰了组织结构以独立于情景细节生成的方式提高记忆质量。
ObjectiveAlthough loss of consciousness associated with moderate or severe traumatic brain injury (TBI) is thought to interfere with encoding of the TBI event, little is known about the effects of mild TBI (mTBI), which typically involves only transient disruption in consciousness.MethodBlast-exposed Afghanistan and Iraq War veterans were asked to recall the blast event. Participants were stratified based on whether the blast was associated with probable mTBI (n= 50) or not (n= 25). Narratives were scored for organizational structure (ie, coherence) using the Narrative Coherence Coding Scheme (Reese et al., 2011) and episodic recollection using the Autobiographical Interview Coding Procedures (Levine et al., 2002).ResultsThe mTBI group produced narratives that were less coherent but contained more episodic details than those of the no-TBI group.ConclusionThese results suggest that mTBI interferes with the organizational quality of memory in a manner that is independent of episodic detail generation.
