科学领域:
- 神经科学是一个神经科学.
- 睡眠医学 睡眠医学
- 数字健康数字健康
背景情况:
- 快速眼动 (REM) 睡眠抑制,以较短的REM延迟和较大的REM分数为特征,是主要抑郁症的已知的实验室标志物.
- 在日常生活中使用消费者可穿戴设备捕捉这些REM睡眠模式的可行性尚未确立.
研究的目的:
- 评估从Apple Watch数据中获得的REM延迟和REM睡眠系数是否可以在日常环境中有效测量.
- 检查可穿戴设备衍生REM睡眠指标与抑郁症状严重程度之间的关联.
主要方法:
- 191名成年人使用Apple Watch记录了15晚的睡眠时间,数据通过自定义iOS应用程序流传.
- 用经过验证的神经网络模型确定睡眠阶段;计算REM延迟和REM睡眠系数.
- 使用贝克抑郁 inventory (BDI) 评估抑郁症的严重程度.
主要成果:
- 平均BDI得分为13.52±6.79,REM睡眠系数为24.05±6.52%,REM延迟时间为103.63±15.44分钟.
- 雷姆睡眠延迟与BDI得分有显著的负相关性 (ρ = -0.673,p < 0.001).
- 雷姆睡眠系数与BDI得分有显著的正相关性 (ρ = 0.678,p < 0.001).
结论:
- 由可穿戴设备衍生的REM延迟和REM比例共同解释了抑郁症状严重程度差异的很大一部分 (62%).
- 这些REM睡眠指标显示,它们可以作为抑郁症的可访问的数字生物标志物.
- 进一步的纵向和干预研究是有必要的,通过修改REM架构来探索治疗潜力.

REM Sleep Behavior Disorder
1.4K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

Sleep-Wake Cycles

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).
