The presence of disproportionate memory impairment with relatively preserved intellectual functioning was examined in 87 survivors of moderate or severe closed head injury. Approximately one-fourth of the patients tested at 5 to 15 and/or 16 to 42 months after injury manifested defective memory on both auditory and pictorial measures despite obtaining Wechsler Verbal and Performance Intelligence Quotients within the average range. The findings indicate that disproportionately severe memory deficit persists in a subgroup of closed head injured survivors which is reminiscent in some cases of the amnesic disturbance arising from other causes. Evaluation of long term memory in relation to cognitive ability could potentially identify important distinctions for prognosis and rehabilitation in head injured patients.
对87名中度或重度闭合性颅脑损伤幸存者进行了研究,以考察在智力功能相对保留的情况下是否存在不成比例的记忆障碍。在受伤后5至15个月和/或16至42个月接受测试的患者中,约四分之一的患者尽管韦氏语言智商和操作智商处于平均范围内,但在听觉和图像测试中均表现出记忆缺陷。研究结果表明,在闭合性颅脑损伤幸存者的一个亚组中,存在不成比例的严重记忆缺陷,在某些情况下,这让人联想到由其他原因引起的失忆障碍。评估与认知能力相关的长期记忆可能有助于确定颅脑损伤患者预后和康复的重要差异。
