BACKGROUND: Anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis is a common type of autoimmune encephalitis characterized by complex clinical signs and variable imaging manifestations. The pathogenesis of the disease is unclear. Syphilis is an infectious disease caused by Treponema pallidum that can invade the nervous and immune systems and cause systemic symptoms. There are few reports of anti-NMDAR encephalitis with syphilis, and the association between them is unknown; both diseases are related to immune system damage...

Cerebellar ataxia is an atypical presentation of anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. In patients with anti-NMDAR encephalitis, cerebellar ataxia often develops simultaneously or sequentially with clinical features of demyelinating disorders, paraneoplastic neurologic syndromes, despite unremarkable brain magnetic resonance imagerying (MRI) findings. Herein, we report a patient with anti-NMDAR encephalitis who developed dizziness and gait ataxia as the initial symptoms, simultaneously showing MRI hyperintensities involving the cerebellum, even before manifesting behavioral and cognitive symptoms...

Introduction Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is one of the most common autoimmune encephalitides. The frequency of anti-NMDAR encephalitis is known to exceed the frequency of any individual viral encephalitis in young subjects. Epileptic seizures are a cardinal symptom in anti-NMDAR encephalitis; a significant amount of pediatric patients exhibit seizures as the first symptom of the disease, and most of them will develop them during the acute phase. The use of antiepileptic drugs (AEDs) is a cornerstone of the treatment of these patients, but the choice of agent and duration of treatment is currently unknown...

Introduction: Paraneoplastic limbic encephalitis (PLE) is a rare disease that presents as rapid onset dementia characterized by short-term memory loss (STM), anxiety, and behavioral changes. Anti-NMDAR antibodies are unfrequently reported in PLE associated with small-cell lung cancer (SCLC). Given that PLE can precede the diagnosis of cancer, it is very important that once infectious, metabolic, nutritional, or structural disorders associated with short-term memory loss are ruled out that vigorous effort must be made to rule out underlying malignancy...

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...

Several studies have certified that autoantibodies play an important role in the manifestation of neuromuscular diseases. Scientists have discovered specific neuronal tumor antibodies in patients with typical paraneoplastic neurological disorders. But in some clinical cases, it is not useful to cure this disease with common treatments unless the autoantibodies are addressed. In addition, recent studies have shown a close relationship between certain antibodies and neuronal surface proteins in some special cases...

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...
