概括
这一元分析揭示了与冲动性相关的物质使用障碍 (SUD) 患者中大脑奖励回路连接的中断. 这些发现为开发有针对性的SUD治疗提供了基础.
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.
- 神经成像是一种神经成像.
背景情况:
- 药物使用障碍 (SUD) 涉及与奖励电路功能障碍相关的冲动和强迫行为.
- 之前的休息状态功能磁共振成像 (rs-fMRI) 研究显示在SUD中不一致的结果.
- 在SUD中识别常见的神经生物学模式对于理解和治疗至关重要.
研究的目的:
- 对rs-fMRI研究进行元分析,以确定SUD中常见的神经生物学模式.
- 研究SUD患者中关键奖励回路区域的连接性改变.
- 探索休息状态功能连接 (rsFC) 和SUD中的冲动性之间的关系.
主要方法:
- 一个全面的元分析53个全脑rs-fMRI研究涉及SUD患者和健康对照.
- 利用基于种子的d绘图工具包来分析前带带皮层 (ACC),前额皮层 (PFC),条纹体,乳头和杏仁体的连接.
- 检查了rsFC模式和冲动性得分之间的相关性 (例如,BIS-11).
主要成果:
- 与健康对照组 (N=1792) 相比,SUD患者 (N=1700) 在皮质-状-甲状腺-皮质回路中表现出显著的干扰.
- 具体的变化包括改变了ACC,PFC,纹状,乳头和杏仁体与下额头 (IFG) 和上额头 (SFG) 等区域的连接.
- 条纹体和中间环状回形 (MCG) 之间减少的rsFC与冲动性得分负相关.
结论:
- SUD的特点是特定的网络异常和大脑奖励回路中的连接中断.
- 这些连接性改变与SUD的冲动性有关.
- 这些发现为旨在恢复SUD患者正常大脑连接模式的干预提供了理论基础.

Substance Use Disorders Affecting Sleep
225
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.

Drug Abuse and Addiction: Pharmacological Phenomena
676
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Drug Dependence
1.2K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

CNS Depressants: Alcohol and Nicotine
373
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...
