Clinical analysis and neuropsychological criteria derived from experimental studies of human amnesic syndromes, particularly the alcoholic Korsakoff's syndrome, have been used to characterise an unusual form of amnesia that occurred in two patients after rupture of an anterior communication cerebral artery aneurysm. Intraoperative observation and multiple CT scans did not reveal focal brain damage. Arteriography showed that both patients had arterial vasospasm. The amnesia has persisted over three years since the surgery. Study of the characteristics of their amnesia showed several features in common with other amnesic syndromes, including severely depressed free recall, and less depressed recognition of visual and verbal material. Chronic amnesic syndromes with characteristics of classical amnesic syndromes occur infrequently after rupture and repair of intracranial aneurysms, and, if not caused by parenchymal haemorrhage, may follow pre-operative vasospasm.
临床分析以及源自人类遗忘综合征（尤其是酒精所致科萨科夫综合征）实验研究的神经心理学标准，已被用于描述两例大脑前交通动脉动脉瘤破裂后出现的一种不寻常失忆形式。术中观察和多次CT扫描均未发现局灶性脑损伤。血管造影显示两名患者均有动脉血管痉挛。自手术以来，失忆症状已持续三年多。对其失忆特征的研究表明，与其他失忆综合征有几个共同特征，包括自由回忆严重受损，而对视觉和语言材料的识别受损程度较轻。具有经典失忆综合征特征的慢性失忆综合征在颅内动脉瘤破裂和修复后很少发生，若不是由实质出血引起，则可能继发于术前血管痉挛。
