概括

注意缺陷多动症 (ADHD) 脑网络在ADHD患者和健康对照者之间稳定性没有显著差异. 然而,较高的ADHD症状严重程度与网络灵活性降低相关.

科学领域:

神经科学是一个神经科学.
系统神经科学系统神经科学
计算精神病学是一种计算精神病学.

背景情况:

注意缺陷多动症 (ADHD) 与大脑功能网络连接的改变有关.
负链接 (反同步) 和网络拓在ADHD稳定性中的作用仍未得到充分探索.

研究的目的:

研究失联性和反同步性对ADHD患者大脑网络稳定性的影响.
用结构平衡理论来比较ADHD亚型中的大脑功能组织与典型的发展个体.

主要方法:

利用结构平衡理论来分析静态功能网络.
在ADHD患者和健康的对照组之间比较大脑功能组织.

主要成果:

在ADHD亚型和健康对照人群之间,没有发现休息状态网络平衡能量的显著差异.
在ADHD行为测量和平衡能量之间观察到负相关性,这表明网络灵活性较低,症状严重程度较高.

结论:

与ADHD相关的网络变化可能更局部,不会显著影响整体网络稳定性或灵活性.
研究结果表明,ADHD症状严重程度的增加与不那么灵活,更平衡的大脑网络状态有关.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Functional Brain Systems: Reticular Formation

Functional Brain Systems: Reticular Formation

The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
