概括
阻塞性睡眠呼吸暂停 (OSA) 与昼夜节律的扰乱有关,导致白天活动减少和睡眠增加. 这项研究证实OSA患者的昼夜活动周期较弱,这表明昼夜调节失调有助于他们的症状.
科学领域:
- 睡眠医学 睡眠医学
- 时间生物学 时间生物学
- 神经学 神经学
背景情况:
- 阻塞性睡眠呼吸暂停 (OSA) 与睡眠碎片化和过度的白天嗜睡 (EDS) 有关.
- 假设循环节律失调会恶化与OSA相关的白天症状.
- 了解睡眠-清醒节奏和OSA中的EDS之间的关系至关重要.
研究的目的:
- 在未经治疗的OSA患者中使用动图来评估睡眠-清醒节奏.
- 为了研究在OSA患者中通过动图测量睡眠-清醒节律参数和EDS之间的关系.
- 为了比较OSA患者和健康对照者 (HC) 之间的睡眠-清醒节奏和日间症状.
主要方法:
- 对中度至重度OSA患者 (呼吸暂停-呼吸暂停指数≥15/h) 和HC进行了为期7天的动图记录.
- 参与者填写了EDS (爱普沃思嗜睡量表,ESS),睡眠质量 (匹兹堡睡眠质量指数,PSQI) 和时间型 (早晨和晚上的问卷,MEQ) 的问卷.
- 对时间型 (MEQ分数) 进行统计分析,以比较组间的睡眠-清醒参数和症状分数.
主要成果:
- 与HC相比,OSA患者的睡眠时间更短,睡眠效率更高,睡眠延迟和碎片化更高.
- 动图显示,在最活跃的10小时期间,平均活动减少,在OSA患者中,白天/夜间活动比较低.
- OSA患者报告ESS和PSQI得分显著更高,以及早晨的时间型比HC少.
结论:
- 患有OSA的患者表现出失调的昼夜睡眠-清醒节律,其特点是白天运动活动减少和白天/夜间活动比率降低.
- 在OSA中这种昼夜节律失调可能与过度的白天嗜睡和白天功能减弱相互关联.
- 研究结果强调了解决昼夜节律障碍在OSA管理中的重要性.

Sleep Apnea
143
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Sleep-Wake Cycles
1.3K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Management of Insomnia
244
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...

Sleepwalking and Sleep Talking
142
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Circadian Rhythms and Gene Regulation
4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Narcolepsy
101
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
