释义

Cotard delusion

中文百科

科塔尔症候群

科塔尔症候群(英语:Cotard's Syndrome),或称科塔尔氏妄想虚无幻想症候群行尸症候群(Walking Corpse Syndrome)、活死人症候群,是一种罕见的精神妄想症,患者虽然意识清楚,但是认定自己已经死亡、不存在,只有精神存在。1880年,由法国神经学家科塔尔(Jules Cotard)首次提出这是一种病症,于一场讲学中称这病为「负面谵妄」(negation delirium),此后以他的名字来命名此症。

由于病例稀少(全球患者仅数百人),不同医生的判断和分析仍具争议。有医师认为,此病症是因服用了抗忧郁药物,间接影响到脑部的新陈代谢而致幻。但是另有医师却并不认同此分析结果。

The Cotard delusion (also Cotard's syndrome and walking corpse syndrome) is a rare mental illness in which an afflicted person holds the delusion that they are dead, either figuratively or literally; yet said delusion of negation is not a symptom essential to the syndrome proper. Statistical analysis of a hundred-patient cohort indicates that the denial of self-existence is a symptom present in 69% of the cases of Cotard's syndrome; yet, paradoxically, 55% of the patients present delusions of immortality.
