摘　　要：目的了解轻型闭合性颅脑损伤即脑震荡患者在受伤后不同时间的记忆功能。方法采用韦氏成人记忆量表对48例受伤后不同时间的患者进行评估,同时取32名健康成人为对照。结果发现长时记忆有4项、短时记忆有3项、瞬时记忆有1项分测验平均成绩明显降低,记忆损害涉及瞬时记忆、短时记忆和长时记忆,患者组异常率为58.3%。受伤后不同时段的患者之间的比较,长时记忆中5项有3项两组之间有显著性统计学差异;短时记忆6项中有5项表现出显著的统计学差异;瞬时记忆和记忆商两组间也存在显著统计学差异。结论脑震荡患者存在不同程度的记忆障碍,涉及记忆的各个环节,受伤后不同时间的病人记忆障碍的程度有一定差异,受伤早期记忆损害的程度较重,随时间的推移,记忆功能有一定程度的恢复。Objective To study memory function in patients with mild closed traumatic brain injury(brain con- cussion)at different time after injury.Methods 48 patients,divided into two groups according to different time after injury,were tested with the revised Wechsler Memory Scale(WMS).32 normal adults served as the control group.Results Average scores of patients decreased obviously on 4 tests for long-term memory,on 3 tests for short-term memory and on 1 test for immediate memory,which showed that memory impairment involved in the three aspects.58.3% of patients were abnormal in memory function.Memory function of patients at different time after in- jury were compared with each other.There were statistical differences on 3 of 5 tests for long-term memory,on 5 of 6 tests for short-term memory between the two groups;differences also existed in immediate memory and memory quo- tient.Conclusion Patients with brain concussion show degrees of dysmnesia relating to the whole process of mem- ory.Dysmnesia of patients at different time after injury is distinct.Memory impairment at earlier period is more seri- ous than that at the later one.Memory function of patients shows some recoveries with the elapse of time.
