Sudden onset of Cotard’s syndrome as a clinical sign of brain tumor

Abstract

We report the clinical case where the sudden onset of a Cotard syndrome in a 69 year old lady lead to the discovery of a multifocal glioblastoma in the right temporo-parietal lobe. Cotard’s syndrome is a rare psychiatric disorder in which the afflicted patient believes he or she is dead. These nihilistic thoughts are the expression of a rare syndrome first described by Jules Cotard in late XIX century. The Cotard’s syndrome has been studied and it seems that its psychopathology can be ascribed to the temporoparietal cortex. Although the Cotard’s syndrome is not part of the DSM-V it is common in psychiatric literature and is included in ICD-10-CM within code F22. It has been described associated with organic lesions and atrophy of the non-dominant temporo-parietal cortex, in pathologies like bipolar disorder, schizophrenia1, subdural hemorrhage2, multiple sclerosis, brain atrophy3 and cerebral infarction4 among others5-7. We observed the case of a female patient, 69 years old, with no relevant past medical history, that was admitted to the John Radcliffe Hospital in Oxford (UK) with an episode of numbness in the left hand and an episode of dizziness whilst at home, duration of symptoms was of 15 minutes and then resolved entirely. She had no history of head trauma. Neurological exam was unremarkable and the stroke team felt a CT scan was not required, however she failed occupational therapy assessment and was not sent home. During the night she developed the delusion of being dead. When being interviewed, in the next day early in the afternoon, she stated: – “I think I’m dead (...) it started during the night, like it was some kind of a dream, but this remain until now” (...) – “Do you rationally think you are dead?” – “I do. It may not make much sense since I realize I have blood pressure when they measure it but I rationally think I am dead.”
