This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.

Background:

Cotard-Syndrome (CS), the delusion of being dead, was first described in 1880.
Literature primarily consists of case reports, often in anxious-depressive, demented, or paranoid patients.
Previous research has not extensively explored the prevalence and psychopathological context of CS.

Purpose of the Study:

To investigate the prevalence of Cotard-Syndrome (CS).
To examine the psychopathological context in which CS occurs.

Main Methods:

Analysis of Austrian data (N=346) from the International Study of Psychotic Symptoms in Schizophrenia.
Diagnosis of CS based on established criteria.

Main Results:

CS was diagnosed in 3 cases (0.87% prevalence).
In all cases, CS developed from nihilistic-hypochondriac delusions and progressive loss of energy.
Patients used visual illusions or spatial displacement to reconcile the delusion of being dead with reality.

Conclusions:

CS can be viewed as a specific manifestation of death-related themes in schizophrenic delusions.
CS may represent a nihilistic delusional identity.
This uncommon psychotic phenomenon remains a significant area for psychopathology and philosophy of mind research.
