Stress Prevention and Stress Management Techniques III01:25

Stress Prevention and Stress Management Techniques III

110
Regular exercise and meditation serve as essential tools in managing stress and promoting physical and mental well-being.
The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...

Physiological Foundation of Stress01:24

Physiological Foundation of Stress

165
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Altered States of Awareness01:06

Altered States of Awareness

493
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Brain Imaging01:14

Brain Imaging

320
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

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.
  • 放射学 放射学是一门学科.

背景情况:

  • 怀孕与显著的神经生物学变化有关.
  • 怀孕期间的孕产妇压力会对孕产妇和胎儿的结果产生负面影响.
  • 基于正念的压力减轻 (MBSR) 是减轻压力的潜在干预措施.

研究的目的:

  • 评估一个为期8周的基于正念的压力减轻 (MBSR) 计划对孕期母亲大脑结构和新陈代谢的影响.
  • 分析在MBSR组和通常护理组的孕妇之间皮质形态学和大脑代谢物度的差异.

主要方法:

  • 对IMPACT BCN随机临床试验的二次分析.
  • 磁共振成像 (MRI) 包括皮质表面积分析和质子磁共振光谱 (1H-MRS) 在妊娠的第三季度.
  • 使用五方面正念问卷 (FFMQ) 评估正念.

主要成果:

  • 与通常护理组相比,MBSR参与者在右上额头区域的表面积显著增加.
  • 1H-MRS显示,在MBSR组中,肌肉内醇度更高.
  • 较高的正念分数 (非判断性,非反应性) 与较大的右上额头区域相关.

结论:

  • 怀孕期间的MBSR计划显著影响母亲的大脑结构,特别是增加额叶表面积.
  • MBSR与母亲大脑代谢物度的变化有关,例如myo-inositol.
  • 怀孕期间的正念实践可能会促进母亲大脑的积极神经可塑性.
