Investigations during the last 10 years have revealed a group of disorders mediated by antibodies against ion channels and synaptic receptors, which cause both neurologic and psychiatric symptoms. In this review, I discuss the process of discovery and immunologic triggers of these disorders, and use anti-NMDA receptor encephalitis to emphasize the importance of understanding the underlying physiopathologic mechanisms in those diseases. A better knowledge of these mechanisms reveals points of convergence with other disorders (e...

A 19-year-old male came to the Emergency Room of our hospital due to an episode of dystonic movements and disorientation 4 days after consuming methamphetamine, which evolved to a catatonic frank syndrome and eventually to status epilepticus. Definitive diagnosis was anti-NMDA receptor encephalitis, an acute inflammation of the limbic area of autoimmune origin in which early diagnosis and treatment are key elements for the final outcome. In this case, initial normal tests and previous methamphetamine poisoning delayed diagnosis, because inhaled-methamphetamine poisoning causes similar clinical symptoms to anti-NMDA receptor encephalitis...

BACKGROUND: N-methyl-D-aspartate (NMDA) receptor encephalitis is an immune-mediated condition that has a broad spectrum of manifestations, including seizures, coma, psychosis, and focal neurological deficits. Although usually a diffuse process, unihemispheric involvement mimicking early stages of Rasmussen encephalitis can occur. Rasmussen's encephalitis is a unique syndrome characterized by progressive hemiplegia, drug-resistant focal epilepsy, cognitive decline, and hemispheric brain atrophy contralateral to the hemiplegia...

We present an atypical case of relapsed anti-NMDAR encephalitis in a young female patient without an associated ovarian teratoma. She presented with recurrent seizure attacks with muscle weakness, psychosis, dyskinesia, autonomic failure and insomnia. She was first misdiagnosed as mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) then Hashimoto's encephalopathy due to diffuse cerebral lesions, elevated serum lactic acid concentration, increased amount of thyroid peroxidase and thyroglobulin antibodies in serum and diffuse lesions of the thyroid gland...

INTRODUCTION: Morbidity and mortality of Herpes simplex virus encephalitis (HSE) remain high. Relapses of neurological signs may occur after initial clinical improvement under acyclovir treatment. METHODS: We report here a case of post-HSE anti-N-methyl-d-aspartate receptor-mediated encephalitis in an adult and perform a systematic search on PubMed to identify other cases in adults. RESULTS: We identified 11 previously published cases, to discuss diagnostic and therapeutic management...

Electroencephalogram (EEG) abnormalities are very common in anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. Extreme delta brush (EDB) is a distinctive EEG pattern that is can be suggestive of the diagnosis; however, the etiology of the EDB remains unclear. Furthermore, there is question with regard to its ictal or interictal nature. We report a 20-year-old woman with anti-NMDAR encephalitis whose serial video-EEG monitoring was obtained at 2, 2.5, 4, and 6 months after admission. There was a long-standing EDB lasting up to several hours, with no evolution in frequency, amplitude, or morphology, and without clear association her frequent orofacial dyskinesia...

OBJECTIVE: Anti-NMDA (N-Methyl-D-Aspartate) receptor encephalitis (NMDA-E) is the second cause of autoimmune encephalitis in adults. The objectives of this presentation are to describe the main clinical elements and rehabilitation specificities. OBSERVATIONS: Three female inpatients (mean age: 25) present with moderate to severe behavioural and/or psychiatric disorders, seizures and presence of associated tumor in one patient. Presence of anti-NMDA antibodies in the cerebrospinal liquid confirmed diagnosis...

Five consecutive cases of anti-NMDA-receptor encephalitis that we encountered were marked by a rapidly fluctuating level of consciousness associated with psychotic and delirious mental states. Opisthotonus, catatonia, and rhythmic and non-rhythmic involuntary movements of the mouth and jaw were also characteristic features of these particular cases. Serious and potentially fatal problems included epilepsia partialis continua, partial and generalized seizures, and respiratory depression, resembling the symptoms of encephalitis lethargica...

Recently, the search for diagnostic antibody markers has drawn considerable attention in relation to autoimmune encephalitis. Among the antibody markers, the most frequently detected is the anti-N-methyl-D-aspartate receptor (NMDAR)antibody. Patients with this antibody develop characteristic clinical features. This disease tends to affect young women, and starts with psychiatric symptoms followed by seizures, involuntary movements, autonomic failure, and respiratory failure. Nearly half of these female patients have ovarian teratoma...

BACKGROUND: Anti-N-methyl-d-aspartate receptor (NMDA-R) encephalitis is a recently identified but increasingly recognized autoimmune paraneoplastic disease. Because these patients present complex neuropsychiatric symptoms due to NMDA-R dysfunction, the optimal methods of sedation/anesthesia remain controversial. Here, we present animal experiment data, along with a related case report, implying the safe and effective use of dexmedetomidine in patients with anti-NMDA-R encephalitis. FINDINGS: (1) Animal experiment: in order to investigate whether dexmedetomidine may interfere with NMDA-R activity, an NMDA antagonist (MK-801) model in rats was used to simulate anti-NMDA-R encephalitis...

The aim of this study was to analyze the clinical presentation and provocation factors of rhabdomyolysis in anti-NMDAR encephalitis. Among the 16 patients with anti-NMDAR encephalitis in our institutional cohort, nine patients had elevated CK enzyme levels and clinical evidence of rhabdomyolysis. Rhabdomyolysis was more frequent after immunotherapy. The use of dopamine receptor blocker (DRB) increased the risk of rhabdomyolysis. None of the patients without rhabdomyolysis received DRBs. Rhabdomyolysis is a frequent complication in anti-NMDAR encephalitis and more common after immunotherapy and the use of DRBs increases the risk...

OBJECTIVE: To precisely describe the initial psychiatric presentation of patients with anti-NMDA receptor (NMDAR) antibodies encephalitis (anti-NMDAR encephalitis) to identify potential clues enhancing its early diagnosis. METHODS: We retrospectively studied the French Reference Centre medical records of every adult patient with anti-NMDAR encephalitis to specify the patients' initial psychiatric symptoms leading to hospitalization in a psychiatric department and the reasons underlying the diagnosis of anti-NMDAR encephalitis...

We describe a 43-year-old patient with subacute appearance of neurological and atypical complaints of anergia, anorexia and weight loss six months earlier. In spite of several admissions in different hospitals, no underlying somatic cause could be found and he was admitted to a psychiatric hospital with a tentative diagnosis of major depressive disorder. Subsequently, he was referred to the unit of medically unexplained physical symptoms within the department of general internal medicine for assessment by the psychiatrist, involved in this programme...

We describe a young woman who developed POTS with positive serum anti-NMDA receptor antibodies and no evidence of encephalitis after vaccination with HPV vaccine, Cervarix. Her symptoms improved significantly with immunomodulatory therapy and re-occurred after immunomodulatory therapy was stopped, suggesting an autoimmune etiology of POTS after vaccination.

Autoimmune encephalitis, an inflammatory disease of the brain, is usually attributed to antibody-mediated damage and dysfunction of neuronal structures. A distinction is made between onconeuronal antibodies (directed against intracellular neuronal antigens with resulting paraneoplastic neurological syndromes) and antibodies directed against neuronal cell surface proteins (with resulting synaptic encephalopathies). Anti-NMDA-Receptor-Encephalitis, the most common form of autoimmune encephalopathy, is characterized by a phased course of disease...
