Abstract

Auditory verbal learning and memory was assessed in 18 patients with moderate-severe closed-head injury (CHI). Compared to a matched control group, performance of the CHI subjects on all measures of the Auditory Verbal Learning Test (AVLT) was significantly worse. Discriminant function analysis correctly classified 90% of subjects as CHI or control using the three most reliable measures of the AVLT. Retention of the learning list following the distractor trial varied with severity of injury as indexed by duration of post-traumatic amnesia (PTA). The more severe the injury (longer PTA), the fewer words were recalled after interference (r = -0.72). Susceptibility of verbal memory to retroactive interference is sensitive to the presence and severity of CHI.

摘要

对18名中重度闭合性颅脑损伤（CHI）患者的听觉言语学习和记忆能力进行了评估。与匹配的对照组相比，CHI受试者在听觉言语学习测试（AVLT）所有指标上的表现明显更差。判别函数分析使用AVLT中最可靠的三项指标，将90%的受试者正确分类为CHI患者或对照组。干扰试验后学习列表的保留情况随创伤后遗忘（PTA）持续时间所指示的损伤严重程度而变化。损伤越严重（PTA越长），干扰后回忆出的单词越少（r = -0.72）。言语记忆对倒摄干扰的易感性对CHI的存在和严重程度敏感。
