概括
与小脑体积的减少有关,特别是在参与非运动功能的后部区域. 这项研究强调小脑.
科学领域:
- 神经成像是一种神经成像.
- 发病学 (Epileptology) 是一个专业的学科.
- 神经解剖学是一个神经解剖学.
背景情况:
- 小脑在中的作用在当前的皮质中心模型中未得到充分研究.
- 以前的研究还没有完全描述中小脑神经解剖学.
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:
- 通过ENIGMA-工作组,利用了1,602名患有的成年人和1,022名对照人的结构性MRI数据.
- 使用深度学习将小脑分为28个子区域.
- 应用线性混合模型来比较类型 (TLE-HS,TLE-NL,GGE,ETLE) 和对照组的体积.
主要成果:
- 在所有类型中观察到大脑小脑总体量的显著减少 (d=0.42).
- 脊髓体 (dmax=0.49) 和后叶区域 (VIIB,Crus I/II,VIIIA,VIIIB叶) 的最大体积损失.
- 早期发作和更长的持续时间与后脑小叶体积减少相关;芬伊托因治疗与后脑叶体积减少相关.
结论:
- 在慢性中,大脑小脑深部和后部区域显示出显著的灰质体积损失.
- 后部子区域对于非运动功能至关重要,显示最大的体积减少.
- 这些发现支持将小脑子子区域纳入的神经生物学模型,因为它们与大脑变化和综合征有关.

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
378
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:
