Seizures: Classification

349
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Arteries of the Lower Limbs

189
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...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

301
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

科学领域:

  • 神经学 神经学
  • 神经科学是一个神经科学.
  • 临床神经生理学 临床神经生理学

背景情况:

  • 之前的研究表明,功能性 (FS) 在单个视频EEG监测 (VEEG) 会议中是一致的.
  • 这项研究研究了多年来在单独的VEEG会话中FS的长期一致性.

研究的目的:

  • 为了确定功能性 (FS) 在多个视频EEG监测 (VEEG) 会议中长时间保持类型,受影响区域和持续时间的一致性.
  • 评估VEEG会话之间的时间间隔与FS一致性程度之间的相关性.

主要方法:

  • 在VEEG会话中评估FS的一致性,使用以下标准:发作类型,涉及的初级/二级解剖区域,运动频率和持续时间.
  • 根据会话中一致的特征数量,将一致性级别分类为低,中等或高.
  • 分析了14名患者的数据,VEEG监测之间的平均间隔为3.8年.

主要成果:

  • 在14名患者中,有13名患者在第一次和第二次VEEG会话之间显示FS类型的一致性.
  • 运动FS在主要解剖区域 (9/12患者) 和其他涉及区域 (9/12患者) 中表现一致.
  • 大多数患者 (10/14) 在FS表现出高一致性,持续时间是最不一致的特征.

结论:

  • 功能性 (FS) 在几年内在个体患者中表现出显著的一致性,支持FS作为稳定的现象的概念.
  • 在VEEG会话间的时间和FS的一致性程度之间没有明确的相关性.
  • 这些发现表明了潜在的新研究方向,以了解功能性的潜在机制.
