主要目标：研究复杂性轻度创伤性脑损伤患者在伤后即刻、伤后1个月和3个月的认知功能，研究设计、方法和程序：本研究采用组间比较。具体而言，患者和健康对照组进行神经心理学评估测量注意力，记忆力和执行功能在三个时间points.Results：调查结果表明，患者表现出显着更差的信息处理和分散注意力，持续的注意力，言语识别和言语流畅性立即受伤后。虽然轻度TBI患者的信息处理和注意力分散在1个月改善，并在3个月后恢复正常，他们的持续注意力仍然显着较差的3个月period.Conclusions：研究结果表明，注意力功能障碍是明显的立即轻度TBI。随着时间的推移，不同的注意力功能似乎以不同的速度恢复，这表明这种情况可能对不同的注意力子类型产生不同的影响。
Primary objective: To examine the cognitive functioning in patients with complicated mild traumatic brain injury immediately post-injury and at 1 and 3 months post-injury.Research design, methods, and procedures: Between-group comparisons were adopted for this study. Specifically, both patients and healthy controls were administered neuropsychological assessments measuring attention, memory and executive functions at three time points.Results: Findings indicate that patients performed significantly more poorly in information processing and divided attention, sustained attention, verbal recognition and verbal fluency immediately post-injury. While the information processing and divided attention of mild TBI patients improved at 1 month and returned to normal at 3 months post-injury, their sustained attention remained significantly poorer over the 3-month period.Conclusions: Findings suggest that attention dysfunction is noticeable immediately following a mild TBI. Different attention functions appear to recover at a different pace over time, suggesting that the condition may have a differential impact on the different sub-types of attention.
