概括
即使在创伤后应激障碍诊断之外,创伤暴露也会损害默认模式网络 (DMN) 的功能,如自我反射和社会认知. 大脑结构保持完整,这表明认知变化是功能介导的,而不是结构性的.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 创伤研究 创伤研究
背景情况:
- 创伤后应激障碍 (PTSD) 研究往往忽略了更广泛的创伤反应.
- 默认模式网络 (DMN) 与受创伤影响的各种认知功能有关.
研究的目的:
- 探索DMN的神经心理功能,在创伤暴露但没有PTSD诊断的个体中.
- 调查DMN功能,认知表现和创伤暴露个体的大脑结构之间的关系.
主要方法:
- 关于DMN和创伤反应的文献综述.
- 一项系统的探索性研究,共27名参与者 (16名受创者,11名对照者).
- 神经成像和神经心理评估DMN的功能.
主要成果:
- 暴露于创伤的个体表现出自我参考处理,社会认知,自传回忆和前能力的降低.
- 与对照组相比,在遭受创伤的组中观察到心灵流浪的增加.
- 尽管存在认知缺陷,但两组之间没有发现显著的体积差异.
结论:
- 在遭受创伤的个体中,与DMN功能相关的认知障碍似乎是功能介导的.
- 维护DMN的结构完整性可能是弹性的一个标记.
- 降低海马体积可能是PTSD的脆弱性因素,而不是仅仅是后果.

Traumatic Brain Injury l: Introduction
25
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Spinal Cord Injury ll: Pathophysiology
25
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
