概括
烟草使用障碍 (TUD) 的男性表现出大脑功能网络拓学的改变,与TUD的女性不同. 这些发现突出了TUD中性别特异的神经机制,为未来的治疗提供了信息.
科学领域:
- 神经科学是一个神经科学.
- 成研究 研究成研究
- 神经成像是一种神经成像.
背景情况:
- 以前的研究表明,吸烟成年人的大脑功能变化存在性别差异.
- 然而,缺乏对烟草使用障碍 (TUD) 中大脑功能拓改变的性别特异性模式的系统调查.
- 本研究通过检查全球,模块化和节点网络效率和连接来解决这一差距.
研究的目的:
- 调查吸烟障碍 (TUD) 患者大脑功能网络拓学变化的性别差异.
- 为了比较全球,模块化和节点级别的拓特征,在男性和女性之间使用TUD和对照.
主要方法:
- 休息状态功能磁共振成像 (fMRI) 扫描从56名TUD参与者 (25名女性) 和66名非TUD对照 (28名女性) 中获得.
- 构建了全脑功能网络.
- 为了分析拓差异,采用了共变率的双向分析与错误发现率校正.
主要成果:
- 与对照组相比,有TUD的男性,但不是女性,表现出明显较低的整体效率.
- 患有TUD的男性在特定的大脑区域的节点总效率显著降低,包括右上尾回形和双侧状回形.
- 较低的节点局部效率在 TUD 的男性左侧偏中心叶区观察到.
结论:
- 患有TUD的男性和女性在他们的大脑功能网络中显示出不同的拓性质.
- 这些网络拓学的性别特异性变化可能是TUD神经机制差异的基础.
- 研究结果为制定基于性别的TUD预防和治疗策略提供了基础.

68
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 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.

01:27CNS Depressants: Alcohol and Nicotine
209
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
