概括
二次性发育,即健康的大脑区域发展成,在人类中是有争议的. 观测数据,特别是来自下丘脑瘤相关的,支持它的发生,可能是通过突触可塑性.
科学领域:
- 神经科学是一个神经科学.
- 发病学 (Epileptology) 是一个专业的学科.
- 临床神经学 临床神经学
背景情况:
- 二次性发生,即在以前正常的大脑区域的发展,是人类的一个有争议的概念.
- 虽然已在动物模型中建立,但由于道德和实际限制,在人类中确定的证明是具有挑战性的.
- 来自人类病例的观察数据对于理解这种现象至关重要.
研究的目的:
- 审查和提出支持人类发生二次性发生的观察证据.
- 检查特定的类型,如下丘脑瘤相关的和海马硬化症,作为二次发生的模型.
- 探索二次性发病的潜在机制和潜在的治疗标.
主要方法:
- 对当代手术系列和人类患者的观察数据的审查.
- 分析患有下丘脑瘤相关的病例,以确定二次性发生的阶段.
- 检查从双和双病理学系列的发现,考虑到海马硬化症.
- 考虑最近的实验数据和突触可塑性与神经元损伤之间的作用.
- 评估手术后的衰减现象,作为一种类似点火的过程的证据.
主要成果:
- 脑下垂体瘤相关的提供了对二次性发作的最有力的证据,显示了所有可观察到的阶段.
- 由于有限的纵向数据和相互矛盾的实验发现,对海马硬化中二次性发病的论证不那么有说服力.
- 突触可塑性被认为是驱动二次发作的更可能的机制,而不是发作引起的神经元损伤.
- 一些患者的手术后缩现象为一种类似于体内点火的过程提供了令人信服的证据.
结论:
- 观测数据强烈表明,二次性发生在人类中,特别是在特定的条件下,如下丘脑瘤相关的.
- 突触可塑性是二次发生的可能机制,而不是仅仅是引起的损伤.
- 进一步的研究,包括网络分析和皮质下干预的探索,是有必要的,以了解和管理二次性发.

Epilepsy and Seizures: Overview
230
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...

Seizures: Classification
443
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:
