To identify if concussive symptoms occur with greater frequency among military personnel with multiple lifetime TBIs and if a history of TBI increases risk for subsequent TBI.
One hundred and sixty-one military personnel referred to a TBI clinic for evaluation and treatment of suspected head injury at a military clinic in Iraq.
Military patients completed standardized self-report measures of concussion, depression and post-traumatic stress symptoms; clinical interview; and physical examination. Group comparisons were made according to number of lifetime TBIs and logistic regression was utilized to determine the association of past TBIs on current TBI.
Patients with one or more previous TBIs were more likely to report concussion symptoms immediately following a recent injury and during the evaluation. Although differences between single and multiple TBI groups were observed, these did not reach the level of statistical significance. A history of any TBI increased the likelihood of current TBI diagnosis, but this relationship was no longer significant when adjusting for injury mechanism, depression and post-traumatic stress symptoms.
Among deployed military personnel, the relationship of previous TBI with recent TBI and concussive symptoms may be largely explained by the presence of psychological symptoms.
确定在有多次终生创伤性脑损伤（TBI）的军事人员中，震荡症状是否更频繁出现，以及TBI病史是否会增加后续发生TBI的风险。
161名军事人员，他们因疑似头部受伤被转至伊拉克一家军事诊所的TBI诊所进行评估和治疗。
军事患者完成了关于脑震荡、抑郁和创伤后应激症状的标准化自我报告测量；临床访谈；以及体格检查。根据终生TBI的数量进行组间比较，并采用逻辑回归来确定既往TBI与当前TBI之间的关联。
有一次或多次既往TBI的患者在近期受伤后及评估期间更有可能报告震荡症状。虽然在单次和多次TBI组之间观察到了差异，但这些差异未达到统计学显著水平。任何TBI病史都会增加当前TBI诊断的可能性，但在调整损伤机制、抑郁和创伤后应激症状后，这种关系不再显著。
在部署的军事人员中，既往TBI与近期TBI及震荡症状之间的关系可能很大程度上由心理症状的存在来解释。
