Anfall av gåshud visade sig vara anti-LGI-1-encefalit

Hi everyone, I have been on a three and a half year journey of nervous system chaos. I have posted here before so you may be able to pull up my posts. Anti GAD65 antibodies have been implicated predominantly in limbic encephalitis in addition to systemic disorders like Type 1 diabetes mellitus. Here a patient presenting with seizures, behavior disturbances, memory and gait abnormalities and peculiar orofacial dyskinesias is reported, who was found to have high titre positivity of Anti-GAD 65 and excellent therapeutic response to steroids GAD65 antibodies have diverse clinical correlates, including SPS, cerebellar degeneration, epilepsy, and type 1 diabetes. 43 In the context of encephalitis, especially with epilepsy, a CSF GAD65 response is evidence of an autoimmune etiology. GAD65 antibody associated autoimmune epilepsy (GAD-epilepsy) is a rare but distinct neurological syndrome with a wide clinical spectrum ranging from mild non-pharmacoresistant epilepsy to refractory TLE , LE , and also extra-limbic encephalitis (ELE) .

Anti-glutamic acid decarboxylase (anti-GAD65) antibodies are a rare cause of autoimmune encephalitis (Malter et al., 2010). Serum anti-GAD65 antibodies are present at low titers in 1% of healthy people and in 80% of type 1 diabetes mellitus patients (Meinck et al., 2001). Anti-GAD65 antibodies (GAD65-Abs) have been described as a biological marker in patients with type 1 diabetes mellitus (T1DM), but also in some patients with neurologic diseases, such as stiff-person syndrome (SPS), cerebellar ataxia, or limbic encephalitis. Of note, glutamic acid decarboxylase 65 (GAD65) is an intracellular enzyme that catalyzes the conversion of GABA, however, AE presenting with anti-GAD65 antibodies is often non-paraneoplastic and shows better immune responsiveness than paraneoplastic LE. 19,20 In addition, anti-GAD65 antibody is related to diverse diseases including AE (GAD65)-antibody encephalitis, and should otherwise raise suspicion of a neurodegenerative disease or other etiolo-gies.9 Likewise, hyperacute presentations are also atypical and a vascular aetiology should be considered in those cases. A recurrent course may point towards an autoimmune aeti-ology but unlike the typical relapsing-remitting

Autoimmun epilepsi

Epilepsy may be more frequent and severe than currently suggested, as ictal semiology may be subtle for these outpatients in whom standard EEG is commonly falsely reassuring. Classical anti–GAD65-associated syndromes were seen in 34 of 36 patients with high concentration (94%): stiff-person syndrome (7), cerebellar ataxia (3), chronic epilepsy (9), limbic encephalitis (9), or an overlap of 2 or more of the former (6). Patients with low concentrations had a broad, heterogeneous symptom spectrum.

glutamate decarboxylase (GAD65) have been found in limbic encephalitis (LE) and other neurological conditions. The direct significance of anti-GAD65-ABs for epilepsy is unclear.

The course of GAD 65 antibody‐associated encephalitis is longer than other autoimmune encephalitides. The clinical symptoms of GAD 65 autoimmune encephalitis mainly manifested as chronic epilepsy, cerebellar ataxia, stiff‐person syndrome, and limbic encephalitis, and combined with or without thyroid autoimmune diseases, type 1 diabetes, and thymoma. 2019-10-19 · CONCLUSION: Encephalitis seems to be a frequent neurological syndrome associated with GAD65-Ab disorders.

Glutamic acid decarboxylase (GAD) antibody-associated encephalitis causes both acute seizures and chronic epilepsy with predominantly temporal lobe onset. This condition is challenging in diagnosis and management, and the incidence of GAD antibody (Ab)-related epilepsy could GAD65-Associated Limbic Encephalitis One autoantibody associated with limbic encephalitis (LE) targets intracellular neuronal antigens (IAg) (GAD65 receptor) and three others target the neuronal surface antigens (SAg) (NMDA [N-methyl-D-aspartate) receptor, VGKC [voltage-gated potassium channel]-complex, and AMPA [α‐amino‐3‐hydroxy‐5‐methylisoxazole‐4‐propionic acid] receptor). The course of GAD 65 antibody‐associated encephalitis is longer than other autoimmune encephalitides. The clinical symptoms of GAD 65 autoimmune encephalitis mainly manifested as chronic epilepsy, cerebellar ataxia, stiff‐person syndrome, and limbic encephalitis, and combined with or without thyroid autoimmune diseases, type 1 diabetes, and thymoma. 2019-10-19 2016-08-01 2020-08-25 The glutamic acid decarboxylase 65-kilodalton isoform (GAD65) antibody is a biomarker of autoimmune central nervous system (CNS) disorders and, more commonly, nonneurological autoimmune diseases.
