记忆被定义为神经系统的一种特性，它能有效地存储和提取信息。在神经病学实践中或在神经病学文献中很少遇到或报告100%的“纯”记忆丧失而不伴有其他智力功能损害，并且不伴有其他神经病学体征或症状或意识状态模糊或改变。在诸如老年性脑疾病、早老性和其他器质性精神病、中毒和缺乏状态、脑炎、创伤后和缺氧后后遗症以及电击治疗和癫痫持续状态等情况下，最常发现记忆丧失与脑功能的广泛紊乱相关。[2]然而，在所有这些疾病中，除了其他智力功能和意识障碍外，通常还有其他相关的神经系统异常。即使在病变局部化的情况下（Korsakoff-Wernicke脑病，
MEMORY has been defined as that property of the nervous system whereby it is effective both in the storage and the retrieval of information. 1 Instances of "pure" memory loss without associated impairment of other intellectual functions and not complicated by the presence of other neurologic signs or symptoms or by clouded or altered states of consciousness are rarely encountered in neurologic practice or reported in the neurologic literature. Memory loss is most frequently found in association with widespread disturbance of cerebral function in conditions such as senile brain disease, the presenile and other organic psychoses, toxic and deficiency states, encephalitis, posttraumatic and postanoxic sequelae, and after electroshock therapy and status epilepticus. 2 In all of these, however, there are usually other associated neurologic abnormalities as well as disturbances of other intellectual functions and of consciousness. Even in those conditions in which the lesions are somewhat localized (Korsakoff-Wernicke encephalopathy,
