This study compared the acute stress disorder and post-traumatic stress disorder (PTSD) symptom profiles in motor vehicle accident survivors who sustained a mild traumatic brain injury (MTBI) or no TBI. Consecutive adult patients who sustained a MTBI (n = 79) and no TBI (n = 92) were assessed for acute stress disorder within 1 month of their trauma and reassessed for PTSD (MTBI: n = 63; non-TBI; n = 72) 6-months post-trauma. Comparable rates of acute stress disorder and PTSD were reported in MTBI and non-TBI patients. Intrusive memories and fear and helplessness in response to the trauma were reported less frequently by MTBI than non-TBI patients at the acute phase. Six-months post-trauma fewer MTBI patients than non-TBI reported fear and helplessness in response to the trauma. These findings suggest that, whereas impaired consciousness at the time of a trauma may reduce the frequency of traumatic memories in the initial month post-trauma, MTBI does not result in a different profile of longer-term PTSD.
本研究比较了在机动车事故中遭受轻度创伤性脑损伤（MTBI）或未遭受脑损伤的幸存者的急性应激障碍和创伤后应激障碍（PTSD）症状特征。对连续的成年患者进行评估，其中遭受MTBI的患者（n = 79）和未遭受脑损伤的患者（n = 92）在创伤后1个月内接受急性应激障碍评估，并在创伤后6个月重新评估PTSD（MTBI组：n = 63；非MTBI组：n = 72）。MTBI患者和非MTBI患者报告的急性应激障碍和PTSD发生率相当。在急性期，MTBI患者报告的侵入性记忆以及对创伤的恐惧和无助感的频率低于非MTBI患者。创伤后6个月，报告因创伤而产生恐惧和无助感的MTBI患者少于非MTBI患者。这些发现表明，虽然创伤时意识受损可能会降低创伤后最初一个月内创伤性记忆的频率，但MTBI并不会导致长期PTSD症状有所不同。
