摘　　要：目的了解脑震荡患者在受伤后不同时间段的记忆功能．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名健康成人为对照组．结果发现患者组长时记忆有4项（经历、1—100、100—1、累加）、短时记忆有3项（再生、触摸、理解）、瞬时记忆有1项（背数）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（P〈0．05）；短时记忆6项中有3项表现出显著的统计学差异（P〈0．05～0．01），短病程组记忆障碍较长病程组严重．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，受伤后不同时间的患者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 brain concussion in different phases alter injury. Methods 48 patients were divided into two groups according to different phases after injury, tested with the revised Wechsler Memory Scale （WMS） . And 32 normal adults were identified as a contrast group. Resuits Average scores decreased obviously in 4 tests of long - term memory, 3 tests of short - term memory and 1 test of immediate memory, which showed that memory impairment involved in the three aspects. 58. 3% of patients were abnormal in memory function. Memory functions of patients in different phases after injury were compared with each other. There were statistical differences in 3 of 5 tests of long - term memory （ P 〈 0. 05 ）, in 3 of 6 tests of short - term memory （ P 〈 0. 05 - 0. 01 ） ; differences also existed in immediate memory and memory Quotient. Conclusion Patients with brain concussion show degrees of dysmnesia relating to the whole process of memory. Dysmnesia in different time after injury is distinct. Memory impairment in earlier period is more serious than that in later. Memory function of patients shows some recoveries by time.
