概括
与健康个体相比,分离性显示出脑部激活和功能连接的明显神经生物学差异. 这些发现突出了分裂性患者的情绪,认知和感官运动处理的改变.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 神经成像是一种神经成像.
背景情况:
- 分离性与有共同的症状,使诊断和治疗复杂化.
- 了解分离性的神经生物学基础对于准确诊断至关重要.
研究的目的:
- 为了研究分离性的神经生物学基础.
- 探索功能磁共振成像 (fMRI) 在认知,情感和休息状态中的差异.
主要方法:
- 17名患有分离性的女性患者和17名健康对照患者接受了fMRI.
- 使用基于任务的 (情感,认知) 和静止状态的fMRI.
- 分析了血液氧气水平依赖 (BOLD) 激活和功能连接 (FC).
主要成果:
- 患者在参与情绪,认知和感官运动处理的大脑区域的激活率较低.
- 在特定的部,部和边缘区域之间观察到休息状态的增加FC.
- 在包括前带皮质 (ACC) 和默认模式网络 (DMN) 在内的网络中观察到 FC 的降低.
结论:
- 分离性与情绪,认知,记忆和感官运动功能的显著神经生物学缺陷有关.
- 分离的严重程度与情绪,认知和记忆处理领域的功能改变有关.

01:13Seizures: Classification
443
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:

152
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
