一些相对选择性海马损伤的患者表现出相应的回忆和识别缺陷。此外，在这些患者中，熟悉性和记忆力都被发现受损。相比之下，其他明显类似损伤的患者尽管记忆力严重受损，但他们的识别能力相对保持不变，其中一些患者已被证明保留了熟悉度。我们在这里报告的情况下，失忆症患者遭受双侧海马损伤和颞顶叶萎缩后一氧化碳中毒。在难度匹配的测试中，他的回忆表现比他的识别记忆受到了更严重的损害，无论是对口头材料还是对视觉材料。此外，他在十项识别测试中有九项在健康匹配对象的范围内。在使用过程分离程序的任务中，患者的熟悉度得到保留，尽管他的回忆受损。这些发现表明，即使在颞顶皮质萎缩的情况下，海马病变的健忘症患者的回忆记忆和识别记忆也可以分离。
Some patients with relatively selective hippocampal damage have shown proportionate recall and recognition deficits. Moreover, familiarity as well as recollection have been found to be impaired in some of these patients. In contrast, other patients with apparently similar damage presented with relatively preserved recognition despite having severely impaired recall, and some of these patients have been shown to have preserved familiarity. We report here the case of an amnesic patient who suffered bilateral hippocampal damage and temporoparietal atrophy after carbon monoxide poisoning. On tests matched for difficulty, his recall performance was more severely impaired than his recognition memory, for verbal as well as for visual materials. Moreover, he performed within the range of healthy matched subjects on nine recognition tests out of ten. In a task using the process dissociation procedure, the patient's familiarity was preserved although his recollection was impaired. These findings indicate that recall and recognition memory can be dissociated in amnesic patients with hippocampal lesions even when temporoparietal cortical atrophy is also present.
