NA A 20-year-old male with no known past medical history presented two months of episodic right-sided weakness. An extensive workup was notable for a lumbar puncture that positive antibodies to the N-methyl-D-aspartate (NMDA) receptor, confirming anti-NMDA receptor (NMDAR) encephalitis. Baseline cardiac included transthoracic echocardiogram (TTE) showed left ventricular (LV) hypokinesis borderl...

Seizures are a prominent clinical feature of encephalitis. Recent data suggest the adaptive as well as innate immune system to be involved directly in the pathomechanism of epileptogenesis. Cytotoxic T-cells and antibody-mediated complement activation are major components of the adaptive immune system, which can induce neurodegeneration, thereby probably contributing to epileptic encephalitis. ...

Treatments for anti-N-methyl-D-aspartate (NMDA) receptor encephalitis include immunotherapy with steroids, intravenous immunoglobulin, plasma exchange, or plasmapheresis as first-line treatments, immunotherapy with rituximab or cyclophosphamide as second-line treatments, and tumor removal. In this systematic review, we evaluated previous studies and examined the association between certain micr...

Catatonia is one of the main symptoms of anti-N-Methyl-D-aspartate receptor (NMDAR) encephalitis. However, it is unknown whether metabolic changes observed with (18)F-Fluorodeoxyglucose positron-emission tomography (FDG-PET) are correlated with the severity of the catatonic symptoms and clinical course. Three patients with anti-NMDAR encephalitis showing variable degrees of catatonia were perfo...

BACKGROUND Encephalitis with antibodies against N-methyl D-aspartate receptor (NMDAR) is recognized as a group of antibody-mediated neuropsychiatric syndromes, which occurs with and without a tumor association. Neoplasm may contribute to the pathogenesis of Anti-NMDAR encephalitis in tumor-positive patients. However, the underlying causes in tumor-negative patients are largely unknown. This is ...

Anti-N-methyl-D-aspartate receptor encephalitis is a recently identified autoimmune disorder with a prominent neuropsychiatric presentation. We present the case of a 15-yearold girl with partial complex seizures with secondary generalization and acute mania with psychotic features. A positive diagnosis of anti-NMDA-receptor encephalitis suggested the specific treatment. Despite first-line immun...

Anti-N-methyl-d-aspartate (anti-NMDA) receptor encephalitis is a newly recognized, potentially fatal, but treatable autoimmune disease. Good outcome predictors include milder severity of symptoms, no need for intensive care unit admission, early aggressive immunotherapy, and prompt tumor removal. We report a case of a young girl aged 3 years 2 months and diagnosed as recalcitrant anti-NMDA rece...

Case presentation: Three-years-old male attended with a generalized tonic-clonic seizure. No history of traumatic brain injury, fever or associated flu-like symptoms. Days before, aggressive behavior, slurred speech, visual hallucination. Only one previous seizure, month ago, without status epilepticus. Electroencephalogram (EEG): brush pattern extreme delta, cerebrospinal fluid (CSF) IgG+ for ...
