[Cotard's syndrome in chronic schizophrenia]

Area of Science:

• Psychiatry
• Neurology
• Clinical Psychology

Background:

• Chronic schizophrenia is a severe mental disorder characterized by psychosis.
• Cotard's syndrome, a rare condition, involves delusions of negation, nihilism, and immortality.

Observation:

• A middle-aged woman with a history of chronic schizophrenia presented with Cotard's syndrome.
• She exhibited profound delusions of negation, believing she had no possessions and that her internal organs were absent.
• The patient also held a fixed delusion of immortality.

Findings:

• The patient's delusions of negation and immortality persisted despite pharmacological interventions.
• This case highlights the complex interplay between schizophrenia and secondary delusional syndromes.

Implications:

• Further research is needed into the neurobiological underpinnings of Cotard's syndrome in schizophrenia.
• Investigating novel therapeutic strategies beyond standard medication is crucial for managing such refractory cases.
• Understanding these complex delusions can improve patient care and diagnostic accuracy in severe mental illness.
