摘要
目的：分析丘脑遗忘症异常的记忆过程，探讨其发病机理。方法：对１２例丘脑卒中病人的病前远、近期记忆内容进行测查，并观察病人病后对近期记忆的保持及形成远期记忆的能力。结果：所有病人均有不同程度的顺行性遗忘，部分病人尚有逆行性遗忘。后者可分为远期记忆内容的遗忘和近期记忆内容的遗忘。两者均可恢复，对近期记忆内容的遗忘恢复不全，留有对病前数小时到２ｄ的记忆空白。顺行性遗忘主要是对近期内容的保持时间过短，难以形成远期记忆。结论：丘脑遗忘症的核心问题是近期记忆的保持障碍和近期及远期记忆的回忆障碍。
Objective:To analysis the abnormal memory process in thalamic amnesia and probe into its mechanism. Methods: The remote and recent memory components before the onset were examined in twelve patients with thalamic stroke and the ability to preserve recent memory and format remote memory after stroke were investigated. Results: All the patients had anterograde amnesia in different degree, and some cases had retrograde amnesia. The later could be divided into two parts:amnesia for remote component and recent component. Both of them recovered, while the later resumed incompletely, leaving the memory lose for hours to 2 days just before the onset. The anterograde amnesia mainly consists in the shorted retention duration. Conclusion: The critical problems in thalamic amnesia are retention impairment for recent memory and the recall disorder for both of recent and remote memory.
