Andrew McKeon, Jennifer A Tracy
The glutamic acid decarboxylase 65-isoform (GAD65) antibody is a biomarker of autoimmune central nervous system (CNS) disorders and, more commonly, non-neurological autoimmune diseases. Type 1 diabetes, autoimmune thyroid disease, and pernicious anemia are the most frequent GAD65 autoimmune associations. One or more of these disorders coexists in approximately 70% of patients with GAD65 neurological autoimmunity. Neurological phenotypes have CNS localization and include limbic encephalitis, epilepsy, cerebellar ataxia, and stiff-person syndrome (SPS), among others...

Convulsive status epilepticus is the most extreme form of seizure. It is a medical and neurological emergency that requires prompt and appropriate treatment. Treatment of convulsive status epilepticus is usually divided into stages/steps. The International League Against Epilepsy has released a new definition of status epilepticus that may help to unify the definition in future studies. Over the last few years new information has become available regarding its management. The Rapid Anticonvulsant Medication Prior to Arrival Trial demonstrated non-inferiority of intramuscular midazolam in early status epilepticus compared with intravenous lorazepam...

Marlene Fischer, Erich Schmutzhard
The posterior reversible encephalopathy syndrome (PRES) is a neurological disorder of (sub)acute onset characterized by varied neurological symptoms, which may include headache, impaired visual acuity or visual field deficits, disorders of consciousness, confusion, seizures, and focal neurological deficits. In a majority of patients the clinical presentation includes elevated arterial blood pressure up to hypertensive emergencies. Neuroimaging, in particular magnetic resonance imaging, frequently shows a distinctive parieto-occipital pattern with a symmetric distribution of changes reflecting vasogenic edema...

OBJECTIVE: Autoimmune encephalitis, represented by anti-leucine-rich glioma-inactivated 1 (anti-LGI1) and anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, has increasing clinical significance based on recent discoveries of neuronal autoantibodies. However, its immunopathogenesis is not fully understood. Here, we investigated whether autoimmune encephalitis is associated with the human leukocyte antigen (HLA) subtypes. METHODS: We compared the HLA genotypes of 11 anti-LGI1 and 17 anti-NMDAR encephalitis patients to the control groups, which consisted of 210 epilepsy patients and 485 healthy Koreans...

The central function of the immune system is to protect the host from environmental agents such as microbes or chemicals, thereby preserving the integrity of the body, and preventing the onset of illness and infection. Moreover, the immune system is constantly challenged to discriminate self vs. non-self and mediate the correct response, a phenomenon called self-tolerance. The failure of mechanisms responsible for self-tolerance and induction of an immune response against components of the self, induces autoimmunity and culminates however, in several autoimmune diseases...

The aim of the paper is to show the various neurological and psychiatric symptoms in coeliac disease (CD). CD is a T cell-mediated, tissue-specific autoimmune disease which affects genetically susceptible individuals after dietary exposure to proline- and glutamine-rich proteins contained in certain cereal grains. Genetics, environmental factors and different immune systems, together with the presence of auto-antigens, are taken into account when identifying the pathogenesis of CD. CD pathogenesis is related to immune dysregulation, which involves the gastrointestinal system, and the extra-intestinal systems such as the nervous system, whose neurological symptoms are evidenced in CD patients...

OBJECTIVE: To describe newly identified autoantibodies associated with cerebellar disorders. DESIGN/METHODS: We first screened the sera of 15 patients with cerebellar ataxia, without any known associated autoantibodies, with immunocytochemistry on mouse brain. After characterization and validation of a newly identified antibody, 85 additional patients with suspected autoimmune cerebellar disease were screened using a cell-based assay. RESULTS: Immunoglobulin G from one of the first 15 patients demonstrated a distinct staining pattern on Purkinje neurons...

The prevalence of medical problems in pregnancy is increasing because of a complex interplay between demographic and lifestyle factors, and developments in modern medicine. Maternal mortality and morbidity resulting from treatable medical conditions, such as venous thromboembolism, epilepsy and autoimmune disease, have not decreased in recent years. This is despite a marked decrease in overall maternal mortality. It is vital that all physicians acquire a basic knowledge and understanding of medical problems in pregnancy...

Febrile infection-related epilepsy syndrome (FIRES, AERRPS, or DESC) is one of the most severe, mostly irreversible, and presumably immune-mediated epileptic encephalopathies affecting healthy children. Refractory status epilepticus or a cluster of seizures start a few days after the onset of an acute febrile illness; however, encephalitis cannot be proved. Sequelae of FIRES are drug-resistant epilepsy and neuropsychological impairments occurring without latency. Clinical knowledge is limited because FIRES is sporadic and extremely rare...

Epilepsy is one of the most widespread serious neurological disorders, and an aetiological explanation has not been fully identified. In recent decades, a growing body of evidence has highlighted the influential role of autoimmune mechanisms in the progression of epilepsy. The hygiene hypothesis draws people's attention to the association between gut microbes and the onset of multiple immune disorders. It is also believed that, in addition to influencing digestive system function, symbiotic microbiota can bidirectionally and reversibly impact the programming of extraintestinal pathogenic immune responses during autoimmunity...

Despite intensive research activity leading to many important discoveries, the pathophysiological mechanisms underlying seizures and epilepsy remain poorly understood. An important number of specific gene defects have been related to various forms of epilepsies, and autoimmunity and epilepsy have been associated for a long time. Certain central nervous system proteins have been involved in epilepsy or acute neurological diseases with seizures either due to underlying gene defects or immune dysfunction. Here, we focus on 2 of them that have been the object of particular attention and in-depth research over the past years: the N-methyl-D-aspartate receptor and the leucin-rich glioma-inactivated protein 1 (LGI1)...

The antiphospholipid syndrome (APS) is an autoimmune disease characterized by the occurrence of venous and/or arterial thrombosis and pregnancy morbidity in the presence of pathogenic autoantibodies known as antiphospholipid antibodies (aPL). APS may be associated with other diseases, mainly systemic lupus erythematosus (SLE). The presence or absence of SLE might modify the clinical or serological expression of APS. Apart from the classical manifestations, APS patients with associated SLE more frequently display a clinical profile with arthralgias, arthritis, autoimmune hemolytic anemia, livedo reticularis, epilepsy, glomerular thrombosis, and myocardial infarction...

Autoimmune encephalitis with GABAB receptor antibodies has been rarely reported. Two cases of GABAB receptor antibodies encephalitis were presented here.Epilepsy was the onset symptom, followed by declined consciousness and frequent seizures. Fever was presented in the whole course of the disease. Myorhythmia of the two hands and pilomotor seizures were shown in the later course of the disease. No specificity was demonstrated in electroencephalograms and magnetic resonance imaging. Sensitive response was shown to the first-line immunotherapy...

INTRODUCTION: Neurological diseases are important co-morbidities found in association with bullous pemphigoid. Various neurological conditions (stroke, Parkinson's disease, dementia, epilepsy and multiple sclerosis) have been reported as associations of this bullous disease; whether these are significant has not been definitely proved. However, the presence of neurological conditions is a predictor of poorer prognosis. OBJECTIVES: Our aim was to examine the association of bullous pemphigoid and neurological diseases in Iranian bullous pemphigoid patients...

Autoimmune neurology is a rapidly evolving new subspecialty driven by the discovery of novel neural- (neuronal- or glial-) specific autoantibodies and their target antigens. The neurologic manifestations affecting the central nervous system include encephalitis, dementia, epilepsy, and movement and sleep disorders. Laboratory testing is now available for most of these neural-specific autoantibodies, which serve as diagnostic markers, in some instances directing the physician toward specific cancer types (e...

Bullous pemphigoid (BP) is a chronic, autoimmune vesiculobullous disease that frequently occurs in the elderly population. Previous epidemiological studies have suggested an association between BP and neurological diseases; some studies, however, showed conflicting results. This study aimed to investigate if patients with BP have significantly higher risks for neurological disorders, compared to controls. A comprehensive search was performed using MEDLINE, EMBASE and Cochrane library databases. Case-control and cohort studies that assessed the relationship between BP and neurological diseases were included...

Ten mammalian diacylglycerol kinase (DGK) isozymes (α-κ) have been identified to date. Our previous review noted that several DGK isozymes can serve as potential drug targets for cancer, epilepsy, autoimmunity, cardiac hypertrophy, hypertension and type II diabetes (Sakane et al., 2008). Since then, recent genome-wide association studies have implied several new possible relationships between DGK isozymes and diseases. For example, DGKθ and DGKκ have been suggested to be associated with susceptibility to Parkinson's disease and hypospadias, respectively...
