One hundred and two consecutive head injured patients were studied at 1 and 12 months after injury. Their performances were compared with a group of uninjured friends. The results indicate that impairment in memory depends on the type of task used, time from injury to testing, and on the severity of head injury (that is, degree of impaired consciousness). Head injury severity indices are more closely related to behavioural outcome early as compared with later after injury. At 1 year, only those with deep or prolonged impaired consciousness (as represented by greater than 1 day of coma, Glasgow Coma Scale of 8 or less, and post traumatic amnesia of 2 weeks or greater) are performing significantly worse than comparison subjects.
对102例连续的头部受伤患者在受伤后1个月和12个月进行了研究。将他们的表现与一组未受伤的朋友进行了比较。结果表明,记忆障碍取决于所使用的任务类型、从受伤到测试的时间以及头部损伤的严重程度(即意识受损程度)。与受伤后期相比,头部损伤严重程度指数在早期与行为结果的相关性更强。在1年时,只有那些意识深度或长时间受损的患者(表现为昏迷超过1天、格拉斯哥昏迷量表评分为8分或更低、创伤后遗忘持续2周或更长时间)的表现明显比对照组差。
