概括

睡眠 (SSD) 和它们的频率 (PSF) 与年轻人的认知发展有关. 较高的螺旋活动通常支持更好的认知,在ADHD中出现了特定的模式.

科学领域:

神经科学与认知发展
睡眠研究睡眠研究
儿童和青少年精神病学儿童和青少年精神病学

背景情况:

睡眠对认知功能至关重要,但研究主要集中在健康的年轻人群中.
了解不同年轻人群中的螺旋活动,包括那些患有精神病/行为障碍的人,至关重要.
这项研究探讨了睡眠旋转特征与整个发育过程中的认知能力之间的关系.

研究的目的:

检查睡眠密度 (SSD) 和峰值频率 (PSF) 与典型发育儿童和青少年认知表现之间的关联.
探索这些协会在青年无药精神病/行为障碍,包括特别关注ADHD.
为了确定童年螺旋活动是否预测青少年的认知结果.

主要方法:

使用睡眠电脑电图 (EEG) 来自456名典型发育儿童和258名青少年的9小时多睡眠图.
包括89名儿童和89名青少年,患有未经药物治疗的精神病/行为障碍.
采用多变量调整的线性回归来将睡眠旋密度 (SSD) 和峰值旋频率 (PSF) 与韦克斯勒认知指数联系起来.

主要成果:

在典型发育的儿童中,较高的SSD和PSF与更好的工作记忆和口头智力相关.
在青少年中,较高的SSD与改善工作记忆和非语言智力有关;较慢的PSF与更好的非语言智力有关.
纵向分析显示,童年SSD预测了典型发育的青少年更好的青少年非语言智力. 精神病/行为障碍中通常没有关联,除了ADHD,儿童高SSD和青少年慢PSF支持工作记忆.

结论:

睡眠可以作为神经和认知成熟的生物标志物,发育变异反映了从童年到青春期的大脑变化.
在未经药物治疗的精神病/行为障碍中观察到改变了线活动.
低频线可能为患有多动症的青少年的工作记忆提供保护机制.

Information Processing Approach

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

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...
