Arteries of the Lower Limbs

181
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...

科学领域:

  • 神经科学是一个神经科学.
  • 神经学 神经学
  • 医疗成像医学成像

背景情况:

  • 涉到异常的大脑电活动影响新陈代谢和功能连接 (FC).
  • 中的间接现象可以影响脑代谢和超出焦点的FC.

研究的目的:

  • 调查是否影响皮质和皮质下大脑结构之间的静止状态功能连接 (FC).
  • 探索如何理解中的FC可以为病理生理学见解和治疗策略提供信息.

主要方法:

  • 在35名患者和28名健康对照中,使用休息状态fMRI分析了功能连接 (FC).
  • 与fMRI同时进行EEG记录有助于减轻间接性发性泄漏 (IED) 的影响.
  • 大脑结构之间的相关系数 (FC值) 在各组之间进行了比较.

主要成果:

  • 与对照组相比,患者表现出较低的FC值.
  • 受影响的连接涉及中部前额叶皮质 (MPFC),海马体,丘脑,杏仁体和副海马圈.

结论:

  • 显著改变了在皮下网络中的静止状态功能连接.
  • 病理性FC模式在子类型之间有所不同,海马体,杏仁体和丘陵体连接的显着减少.
  • 改变的FC可能会先于临床症状,可能有助于早期诊断的认知和情绪障碍.
