概括

创伤性脑损伤 (TBI) 可以导致睡眠障碍. 神经成像显示白质损伤,特别是在未切割的囊,与TBI后的失眠有关.

科学领域:

神经科学是一个神经科学.
神经学神经学
睡眠医学睡眠医学

背景情况:

睡眠障碍是创伤性脑损伤 (TBI) 后常见的神经精神病症状.
现有的研究缺乏对与TBI后睡眠问题相关的神经成像发现的全面审查.
了解这些神经成像相关性对于管理TBI恢复至关重要.

研究的目的:

系统地审查TBI后与睡眠障碍相关的神经成像变化.
确定特定的神经成像模式和与TBI后睡眠问题相关的大脑区域.

主要方法:

对21项涉及3176名TBI患者和396名对照者的研究进行了系统审查.
来自计算机断层扫描 (CT),磁共振成像 (MRI) 和定量电脑图 (qEEG) 的神经成像数据的分析.

主要成果:

急性CT异常并不能可靠地预测失眠.
扩散张力成像 (DTI) 测量了轴突完整性,特别是在皮层-皮下白质组织中,如未经切割的囊,与自我报告的睡眠障碍有很强的相关性.
定量脑电图 (qEEG) 显示,TBI患者在睡眠期间的Delta功率下降和Beta功率增加,这表明下丘脑的参与.

结论:

白质完整性,特别是在特定区域,是TBI后睡眠障碍的显著神经成像相关因子.
qEEG的发现表明,下丘脑在TBI相关睡眠问题的发病过程中可能发挥作用.
需要进一步的功能神经成像研究来澄清TBI后睡眠障碍背后的神经电路.

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,...

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...
