概括

在急性缺血性中风患者中,睡眠 (SS) 的数量,持续时间和幅度减少,影响认知功能. 睡眠指数N2的变化可能表明中风后的认知障碍.

科学领域:

神经科学是一个神经科学.
睡眠医学睡眠医学
认知神经学认知神经学

背景情况:

睡眠 (SS) 是非快速眼动 (NREM) 睡眠的关键脑电图特征,与记忆巩固和认知功能有关.
研究表明,SS特征,生理衰老和认知衰退之间存在关联.
急性缺血性中风可以显著影响神经和认知功能.

研究的目的:

调查急性缺血性中风患者SS数量,幅度和持续时间的变化.
分析中风患者中SS参数和认知功能 (通过MoCA评估) 之间的关系.
探索SS作为脑卒中后认知评估的生物标志物的潜力.

主要方法:

对314名患者 (229名中风患者,85名对照患者) 进行过多睡眠图 (PSG) 的回顾性研究.
在中风和对照组之间比较SS参数 (数量,指数,持续时间,振幅) 和MoCA得分.
多重线性回归分析以确定影响中风患者MoCA得分的因素.

主要成果:

与对照组相比,中风患者的MoCA分数较低,NREM2/NREM3中的SS数和指数减少,N2中的SS平均持续时间较短,N3中的SS最大幅度较低.
脑卒中患者的MoCA得分与年龄,睡眠效率和N2睡眠线索 (N2-SS) 指数显著相关.
在中风患者中观察到SS数量,持续时间和振幅的减少,N2-SS变化可能与认知障碍严重程度有关.

结论:

急性缺血性中风与睡眠活动的显著减少有关.
睡眠线索活动减少可能会导致中风后的认知障碍.
睡眠线圈参数,特别是N2-SS指数,显示为客观的生理指标,用于评估中风幸存者的认知功能.

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

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.
Understanding the concepts of physical dependence,...

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

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.
RBD is significantly associated with...

Correlations

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
