背景情况:
- 带有中尖的良性 (BECTS) 是一种常见的儿童.
- 行为问题和认知障碍经常伴随BECTS.
- 之前对BECTS大脑结构的研究使用单变量分析产生了不一致的发现,与不清楚的神经递质关联.
研究的目的:
- 通过使用多变量方法,研究BECTS的未使用毒品的儿童的大脑结构变化.
- 在BECTS中探索灰色物质体积 (GMV) 变化和神经递质系统之间的关系.
- 为了更清楚地了解BECTS的基础的神经生物学和分子机制.
主要方法:
- 结构磁共振成像 (MRI) 对21名BECTS药物素朴儿童和35名健康对照 (HC) 进行.
- 基于源的形态测量 (SBM) 用于将分段灰质体积 (GMV) 图像分解为独立组件 (IC).
- 空间相关性分析检查了GMV变化,发作频率和神经递质系统之间的关系.
主要成果:

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
347
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:
