概括
睡眠障碍导致的慢性耳声与淋巴系统功能障碍有关,MRI检测结果表明. 这些干扰可能解释了与耳相关的睡眠问题背后的神经机制.
科学领域:
- 神经成像是一种神经成像.
- 睡眠医学 睡眠医学
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 慢性耳声通常与睡眠障碍同时发生,但潜在的神经机制尚不清楚.
- 淋巴系统负责大脑的废物清理,在维持大脑平衡中起着至关重要的作用,可能与睡眠调节有关.
研究的目的:
- 用多式磁共振成像 (MRI) 调查慢性耳和睡眠障碍患者的潜在淋巴系统功能障碍.
主要方法:
- 一项前性研究涉及30名带有睡眠障碍 (TSD) 患者的耳声,30名没有睡眠障碍 (TNSD) 患者的耳声,以及38名健康对照 (HC).
- 采用多式核磁共振 (MRI) 来评估淋巴系统指数,包括胆管体体积 (CPV),扩大周周血管空间 (EPVS) 和沿周周血管空间 (DTI-ALPS) 进行扩散张力图像分析.
- 临床评估包括匹兹堡睡眠质量指数 (PSQI) 和耳障碍问卷 (THQ).
主要成果:
- 与HC相比,TSD组的CPV和EPVS显著更高 (p < 0.0001).
- 而TNSD组的DTI-ALPS值明显低于HC组的DTI-ALPS值 (p = 0.044).
- 在慢性耳患者中,降低的DTI-ALPS与PSQI得分负相关 (r = -0.428,p = 0.001),而增加的CPV和EPVS与PSQI得分正相关 (r = 0.374,p = 0.005;r = 0.335,p = 0.013). 降低的ALPS也与THQ分数负相关 (r = -0.378,p = 0.005).
结论:
- 这项研究表明,慢性耳患者的淋巴功能受损,可能与睡眠障碍有关.
- CPV,EPVS和ALPS可以作为有价值的神经成像标记,以了解慢性耳与睡眠障碍并发症的神经病理机制.

Substance Use Disorders Affecting Sleep
225
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Management of Insomnia
328
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
