概括
患有中尖 (BECTS) 良性的儿童在语言任务中表现出大脑活动的改变. 新发病的BECTS可能涉及补偿性大脑激活,而药物和疾病持续时间会影响语言功能.
科学领域:
- 神经科学是一个神经科学.
- 儿科神经学 儿科神经学
- 认知神经科学 认知神经科学
背景情况:
- 带有中尖的良性 (BECTS) 是一个常见的儿童综合征.
- 神经心理学研究表明,BECTS儿童的语言障碍.
- 任务激活功能磁共振成像 (fMRI) 提供了一种在特定任务期间调查大脑功能的方法.
研究的目的:
- 用任务激活的fMRI研究BECTS儿童的语言功能.
- 为了比较在语言任务期间的脑激活模式,在新发病的药物原始BECTS (NODN-BECTS),药物治疗BECTS (Med-BECTS) 和健康对照 (HC) 的儿童之间进行.
- 探索大脑激活,学业表现和状态之间的关系.
主要方法:
- 在三个组进行了语言任务fMRI研究:NODN-BECTS (n=11),Med-BECTS (n=17) 和HC (n=18).
- 使用3.0TMRI扫描仪获取数据,并使用MATLAB和SPM12进行分析.
- 统计分析包括一个样本的t测试用于 intra-group激活和两个样本的t测试用于跨组比较. 收集了普通话学校考试成绩.
主要成果:
- 与HC相比,NODN-BECTS组在与语言相关的区域 (例如,左上额头,小脑) 显示了额外的激活.
- 与NODN-BECTS和HC组相比,Med-BECTS组表现出与语言相关的区域 (例如,左侧胰岛,额头回转,背回转) 的活化减少.
- 与HC相比,Med-BECTS和NODN-BECTS组的普通话学校考试平均分数较低,但只有Med-BECTS和HC之间的差异接近统计学意义 (p=0.074).
结论:
- 任务激活的fMRI显示,在新发病的BECTS中,语言网络中的补偿性大脑激活.
- 在BECTS中,抗发作药物和/或更长的疾病持续时间可能会对与语言相关的大脑区域和功能能力产生负面影响.
- 需要进一步的研究来了解BECTS及其对认知功能,特别是语言的治疗的长期影响.

Seizures: Classification
406
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:

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...
