Cotard’s syndrome


Cotard’s delusion or walking corpse syndrome is a monothematic delusion in which the patient denies existence of one’s own body to the extent of delusions of immortality.


The first description of the syndrome was made in 1880 by the French psychiatrist Jules Cotard,, who presented the case of a female patient in a lecture. He originally named it “hypochondriac delusion”, and some years later “delusion of negations”, while it was named “Cotard delusion” after his death. In international literature, the terms “nihilistic delusion” and “Cotard’s syndrome” prevailed over “delusion of negations” and “Cotard delusion”.
