Longitudinal Changes of Regional Cerebral Blood Flow on a Single-Photon Emission Computed Tomography (SPECT) Scan in a Patient With Schizophrenia Having Cotard's Syndrome.

Cotard's syndrome is a rare clinical condition characterized by the presence of nihilistic delusions, delusions of immortality, depressive mood, and anxiety. Longitudinal changes in regional cerebral blood flow (rCBF) obtained under different conditions with and without Cotard's syndrome have rarely been reported in the literature. We report a case of a patient with Cotard's syndrome in whom longitudinal rCBF was assessed using single-photon emission computed tomography (SPECT).

Case report: A case of anti-recoverin antibody-positive encephalitis exhibiting Cotard and Capgras delusions that was successfully treated with electroconvulsive therapy.

Recoverin is a neuron-specific calcium-binding protein that is mainly located in the retina and pineal gland. Few reports have described patients with anti-recoverin antibody-positive encephalitis, and no cases of psychosis associated with this encephalitis have been reported. We report a patient with anti-recoverin antibody-positive encephalitis with Cotard and Capgras delusions who was successfully treated with electroconvulsive therapy (ECT).

A fatal case of fulminant neuroleptic malignant syndrome: A case report.

Background: Neuroleptic malignant syndrome (NMS), a rare but potentially life-threatening adverse reaction to treatment with antipsychotic drugs, is characterized by hyperthermia, muscle rigidity, impaired consciousness, and autonomic disturbances. Some reports have described rapidly progressing cases of NMS resulting in death within several days. This report describes a clinical course of fatal and fulminant NMS in a patient with schizoaffective disorder.
