We describe a patient, RM, who suddenly became amnesic for premorbid autobiographic events in the absence of any known precipitating event. Learning abilities as well as semantic knowledge were normal. Knowledge of famous facts and persons was good, although not perfect. Whether RM suffered from organic or psychogenic isolated retrograde amnesia (IRA) could not be established on the basis of available clinical and neuropsychological elements. Regardless of its aetiology, RM's case respects the boundaries between semantic and episodic memory and so gives further support to the distinction between these two memory systems.
我们描述了一位名为RM的患者，他在没有任何已知诱发事件的情况下，突然对病前的自传性事件失忆。学习能力以及语义知识均正常。对著名事实和人物的了解良好，尽管并不完美。根据现有的临床和神经心理学因素，无法确定RM是患有器质性还是心因性孤立性逆行性遗忘症（IRA）。无论病因如何，RM的病例符合语义记忆和情景记忆之间的界限，因此进一步支持了这两种记忆系统之间的区别。
