许多以前的研究调查创伤性脑损伤（TBI）后的长期认知障碍，重点是极其严重的受伤患者，依赖于主观报告的变化，并没有使用人口统计学相关的对照数据。本研究的目的是调查TBI后10年的认知障碍及其与损伤严重程度的关系。对60名TBI和43名对照参与者进行了注意力、处理速度、记忆力和执行功能测试。TBI组在处理速度方面表现出明显的认知障碍（符号数字模态测试[SDMT]，Smith，1973;数字符号编码，Wechsler，1997），记忆（Rey听觉言语学习测试[RAVLT]; Rey，1958; Lezak，1976），门和人测试; Baddeley，Emslie & Nimmo-Smith，1994）和执行功能（Hayling C [Burgess & Shallice，19971 and SART errors，Robertson，Manly，Andrade，Baddeley & Yiend，1997）。Logistic回归分析表明，SDMT，雷伊AVLT和海林C和SART错误最强烈区分组的注意/处理速度，记忆和执行功能，分别领域。在所有领域，更严重的损伤与更差的测试表现显著相关。这项研究表明，认知障碍是目前许多年后，创伤性脑损伤，并与损伤的严重程度。
Many previous studies investigating long-term cognitive impairments following traumatic brain injury (TBI) have focused on extremely severely injured patients, relied on subjective reports of change and failed to use demographically relevant control data. The aim of this study was to investigate cognitive impairments 10 years following TBI and their association with injury severity. Sixty TBI and 43 control participants were assessed on tests of attention, processing speed, memory, and executive function. The TBI group demonstrated significant cognitive impairment on measures of processing speed (Symbol Digit Modalities Test [SDMT], Smith, 1973; Digit Symbol Coding, Wechsler, 1997), memory (Rey Auditory Verbal Learning Test [RAVLT]; Rey, 1958; Lezak, 1976), Doors and People tests; Baddeley, Emslie & Nimmo-Smith, 1994) and executive function (Hayling C [Burgess & Shallice, 19971 and SART errors, Robertson, Manly, Andrade, Baddeley & Yiend, 1997). Logistic Regression analyses indicated that the SDMT, Rey AVLT and Hayling C and SART errors most strongly differentiated the groups in the domains of attention/processing speed, memory and executive function, respectively. Greater injury severity was significantly correlated with poorer test performances across all domains. This study shows that cognitive impairments are present many years following TBI and are associated with injury severity.
