概括
和偏头痛并发症与显著的大脑结构差异有关. 患者的结构性大脑变化可能会影响偏头痛的发展,反之亦然.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 偏头痛和经常同时发生,这表明存在复杂的潜在相互作用.
- 以前的研究还没有利用大脑形态分析来研究和偏头痛之间的关系.
研究的目的:
- 使用先进的神经成像技术,研究和并发性偏头痛没有光环 (EM) 患者的结构性大脑变化.
- 探索大脑形态与并发性和偏头痛的表现之间的潜在双向关系.
主要方法:
- 在30名EM患者,30名控制者 (EC) 和20名健康控制者 (HC) 上,采用了基于声素的形态测量 (VBM),基于表面的形态测量 (SBM) 和结构共差网络 (SCN).
- 分析了灰质体积,皮质厚度和图形理论网络指标,以确定群体差异.
- 与观察到的大脑结构变化相关的临床数据 (头痛持续时间和频率).
主要成果:
- 与HC相比,VBM显示EM患者的右极灰质缩,与头痛持续时间负相关.
- 在EM患者中,SBM在多个左半球区域 (岛屿,后带膜,后中心,中,状回转) 确定了皮质缩,皮质厚度与头痛频率具有正相关性.
- 在SCN分析中,右后中心 (EM与HC) 的节点间中心性降低,右状 (EM与EC) 的节点程度降低.
结论:
- 在患有并发性和没有光环的偏头痛的患者中存在显著的结构性大脑差异.
- 研究结果表明,偏头痛发作可能会影响患者的大脑结构,而异常的大脑结构可能会导致并发性和偏头痛的发展.
- 需要进一步的研究来阐明大脑结构在这种并发症中的确切作用.

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
309
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:
