概括

神经抗体在长期中很罕见 (0.4%),但在存在时表明自身免疫性疾病. 这些抗体仅在叶患者中发现,与特定的临床特征有关.

科学领域:

神经学神经学
免疫学免疫学免疫学

背景情况:

神经元抗体是自身免疫性脑炎的关键生物标志物,这种疾病会导致神经系统的快速衰退.
了解长期的患病率和相关性对于诊断和管理至关重要.

研究的目的:

确定长期患者中神经元表面和细胞内抗体的频率.
确定与这些抗体存在相关的临床和实验室特征.

主要方法:

测试了223名患者 (没有自身免疫性脑炎症状) 和12名患者和新的神经症状的血清.
对抗体阳性和阴性组之间的临床和实验室数据进行了比较.
评估了ACES,APE分数和ONES检查清单的诊断准确性.

主要成果:

抗体在0.4%的长期患者中被发现 (一种病例是抗GAD,耐药MTLE-HS).
在患有和新症状的患者中,33.3%具有抗体 (抗GAD,抗LGI1,抗Hu).
抗体阳性患者出现了晚期发作,发作频率波动和药物反应;所有人都患有叶 (TLE).

结论:

神经抗体在孤立的长期中很罕见,但与TLE强烈相关,特别是在抗GAD病例中的MTLE-HS.
该ONES检查清单显示了高灵敏度和特异性,用于识别具有神经元抗体的患者.

关键词:

抗-GAD的使用方法.与自身免疫相关的.神经元抗体的神经元抗体在叶发作.

Epilepsy and Seizures: Overview

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
