Postconcussive symptoms after mild traumatic brain injury (MTBI) may be exacerbated by anxiety associated with posttraumatic stress. The aim of this study was to investigate the relationship between postconcussive symptoms and posttraumatic stress disorder (PTSD) in an MTBI population. Survivors of motor vehicle accidents who either sustained an MTBI (N = 46) or no TBI (N = 59) were assessed 6 months posttrauma for PTSD and postconcussive symptoms. Postconcussive symptoms were more evident in MTBI patients with PTSD than those without PTSD, and in MTBI patients than non-TBI patients. Further, postconcussive symptoms were significantly correlated with PTSD symptoms. These findings indicate that postconcussive symptoms may be mediated by an interaction of neurological and psychological factors after MTBI.
轻度创伤性脑损伤（MTBI）后的脑震荡后症状可能会因创伤后应激相关的焦虑而加重。本研究的目的是调查MTBI人群中脑震荡后症状与创伤后应激障碍（PTSD）之间的关系。在创伤后6个月，对机动车事故幸存者进行评估，其中遭受MTBI的患者（N = 46）或未遭受创伤性脑损伤（TBI）的患者（N = 59）被评估是否患有PTSD和脑震荡后症状。与无PTSD的MTBI患者相比，患有PTSD的MTBI患者的脑震荡后症状更明显，并且MTBI患者比非TBI患者的症状更明显。此外，脑震荡后症状与PTSD症状显著相关。这些发现表明，MTBI后脑震荡后症状可能由神经和心理因素的相互作用介导。
