BACKGROUND: Anti-NMDA receptor antibody (anti-NMDAr) encephalitis, although still a rare condition, is well known to neurologists as it is the leading cause of non-infectious acute encephalitis in young women. However, this is less well known to gynecologists, who may have a decisive role in etiological management. Indeed, in 30-60% of cases in women of childbearing age, it is associated with the presence of an ovarian teratoma, whose removal is crucial in the resolution of symptomatology...

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a potentially fatal autoimmune disease, characterized by autoantibody-mediated neurotransmission impairment in multiple brain locations. The course of this condition often comprises altered mental status, autonomic dysfunctions, refractory seizures and hyperkinetic movement disorders. Available disease-modifying therapies include corticosteroids, i.v. immunoglobulins, plasma exchange, rituximab and cyclophosphamide. In a subgroup of patients not responding to B-cell depletion, bortezomib, a proteasome inhibitor, has shown promising evidence of efficacy...

We herein report a 50-year-old man with alcoholic cirrhosis who developed loss of consciousness and tremor of the upper limbs. Magnetic resonance imaging findings were suggestive of limbic encephalitis with bilateral hippocampal damage, and a cerebrospinal fluid (CSF) examination confirmed anti-N-methyl-D-aspartate (NMDA) and anti-glutamate receptor antibodies. Despite initial corticosteroid therapy, meningeal irritation symptoms appeared, owing to the development of cryptococcal meningitis (CM), diagnosed by the detection of cryptococcal capsular polysaccharide antigen in the follow-up CSF analysis...

A 61-year-old Japanese man presented with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. NR1 antibodies were detected in his cerebrospinal fluid. Chest computed tomography revealed lung tumor. The patient was diagnosed with paraneoplastic anti-NMDAR encephalitis associated with lung cancer and treated with two cycles of intravenous high-dose methylprednisolone and one cycle of intravenous immunoglobulin. However, he died one year later without improvement. An autopsy confirmed small-cell lung cancer (SCLC)...

Brain positron emission tomography imaging with 18Fluorine-fluorodeoxyglucose (FDG-PET) has demonstrated utility in suspected autoimmune encephalitis. Visual and/or assisted image reading is not well established to evaluate hypometabolism/hypermetabolism. We retrospectively evaluated patients with autoimmune encephalitis between 2003 and 2018. Patients underwent EEG, brain magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) sampling and autoantibodies testing. Individual FDG-PET images were evaluated by standard visual reading and assisted by voxel-based analyses, compared to a normal database...

Immune-mediated inflammatory diseases of the central nervous system (CNS) are a group of neurological disorders in which inflammation and/or demyelination are induced by cellular and humoral immune responses specific to CNS antigens. They include diseases such as multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), acute disseminated encephalomyelitis (ADEM) and anti-NMDA receptor encephalitis (NMDAR encephalitis). Over the years, many in vivo and in vitro models were used to study clinical, pathological, physiological and immunological features of these neuroimmunological disorders...

OBJECTIVE: The gold standard for diagnosing anti-NMDAR encephalitis is demonstration of the antibody in CSF. Clinical diagnostic criteria have been proposed for when this is not available in a timely manner which is evaluated, in this study, for a psychiatric population. METHODS: This study retrospectively assessed the proposed criteria in patients presenting to psychiatric services for the first time with known anti-NMDAR antibody status. Antibody positive cases were derived from the literature (conception to December 2019) and a state wide (Queensland, Australia) cohort...

This article reports the case of a 40-year-old male patient with isolated metamorphopsia and visual pseudohallucinations lasting for 2 weeks. As the ophthalmological findings were not pathological, a further neurological examination was performed. After diagnosis of anti-N-methyl-D-aspartate (NMDA) receptor encephalitis, which can be manifested in various psychiatric, neurological and ophthalmological ways, the oligosymptomatic patient received high-dose corticosteroid treatment with intravenous immunoglobulins, which stopped the symptoms...

Optic neuritis is an inflammatory demyelinating disorder of the central nervous system. Anti-NMDA receptor (NMDAR) antibodies encephalitis is also mediated by the inappropriate immunological response. We report a girl who was readmitted because of unilateral eye pain and vision impairment in the remission period of anti-NMDAR encephalitis. Based on the limited available literature on the treatment of optic neuritis associated with anti-NMDA receptor antibody, she was treated with a combination of corticosteroids and intravenous immunoglobulin with clinical improvement...

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a serious autoimmune disorder characterized by psychiatric symptoms, seizures and movement disorder. Predisposing factors have been reported since the time it was described, and its pathophysiology has been tried to be clarified over the years. Although overlap with other demyelinating diseases had been reported, such an association between Multiple Sclerosis (MS) anti ANTİ-NMDAR encephalitis is limited to only a few case reports. In this article, a patient diagnosed with relapsing remitting multiple sclerosis (RRMS) for ten years who then developed NMDA-R encephalitis while on disease modifying treatment will be presented and possible common pathophysiology with previously reported literature will be discussed...
