概括
与小脑灰质体积的减少有关,特别是在后部区域. 这种体积损失与早期发作和更长的疾病持续时间相关,这表明小脑.
科学领域:
- 神经成像是一种神经成像.
- 的研究研究.
- 小脑解剖学 大脑小脑解剖学
背景情况:
- 小脑在中的作用在当前的皮质中心模型中未被充分探索.
- 以前的研究还没有完全描述患者小脑神经解剖学变化的特征.
研究的目的:
- 与健康对照人群相比,在患有的成年人中量化区域大脑小叶体积.
- 研究小脑体积与特征 (发病年龄,持续时间,治疗) 和大脑皮层厚度之间的关系.
主要方法:
- 利用了来自1602名患者和1022名对照者的结构磁共振成像 (sMRI) 数据 (ENIGMA-联盟).
- 采用深度学习方法将小脑分为28个子区域.
- 应用线性混合模型来比较不同类型的小脑体积,并与临床变量相关联.
主要成果:
- 在所有类型中观察到小脑总体积的显著减少 (d = 0.42).
- 最大的体积损失发生在小脑后部区域 (大脑髓体,第七B 叶片,I/II,VIIIA,VIIIB 叶片),与更早发作和更长的持续时间有关.
- 在叶与海马硬化 (TLE-HS) 和外焦点 (ETLE) 中体积损失最为明显;芬伊托因治疗与后叶体积减少有关.
结论:
- 提供了强有力的证据,在慢性中,深小脑和后叶灰色物质体积损失.
- 后部子区域,涉及非运动功能,显示最大体积损失.
- 在综合征中,小脑损伤的变异性需要精确地纳入的神经生物学模型.

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
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:
