概括
互联网游戏障碍 (IGD) 在控制抑制控制和视听处理的大脑区域显示局部功能障碍. 这些变化与神经递质系统的改变有关,这表明针对GABAergic和胆固醇系统的潜在治疗方法.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 放射学 放射学是一门学科.
背景情况:
- 互联网游戏障碍 (IGD) 涉及对抑制控制至关重要的大脑皮层功能障碍,但其神经生物学基础尚未完全理解.
- 研究IGD中的局部内在神经活动 (INA) 改变对于理解其神经生物学至关重要.
- 需要探索INA变化与临床特征之间的关系,以及潜在的分子架构.
研究的目的:
- 通过静止状态功能磁共振成像 (rs-fMRI) 来研究互联网游戏障碍 (IGD) 患者的局部内在神经活动 (INA) 改变.
- 确定这些INA变化是否与IGD的临床特征相关.
- 探索与这些神经变化相关的分子架构,并评估已识别的生物标志物的诊断潜力.
主要方法:
- 从rs-fMRI利用低频波动的分数幅度 (fALFF) 和区域同质性 (ReHo) 来评估IGD中的本地INA.
- 进行了相关性分析,将ReHo和fALFF的发现与临床数据和PET/SPECT衍生分子图进行联系.
- 使用接收器运行特征 (ROC) 曲线分析,以评估fALFF和ReHo的诊断准确性,以区分IGD与健康对照.
主要成果:
- 与对照人群相比,IGD患者在前额叶皮质中呈现出增加的ReHo和fALFF.
- 在叶,叶和小脑中观察到降低的ReHo,小脑的ReHo与成严重程度相关.
- 通过ReHo和fALFF识别的改变的大脑区域有效地将IGD与健康对照区分开来,交叉模式的相关性指向单胺,胆能和GABAerg系统.
结论:
- 视听和抑制控制回路的局部功能障碍是IGD的特征.
- 这些神经缺陷可能与神经递质系统的改变有关,包括单胺,胆固醇和GABAergic通路.
- 研究结果表明,IGD的潜在治疗策略包括GABAergic受体激活剂和胆固醇受体抑制剂.

Attention-Deficit/Hyperactivity Disorder
50
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....

Substance Use Disorders Affecting Sleep
163
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.
