概括
对感觉寻求 (SS) 冲动性的遗传影响与早期物质使用开始密切相关. 了解这些与冲动性的遗传联系可以帮助防止未来的物质参与.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 精神病学是一个精神病学.
背景情况:
- 冲动性是吸毒的关键因素之一.
- 不同的冲动性领域 (例如,感觉寻求,紧迫性) 与物质使用阶段的相关性不同.
- 了解对冲动性的遗传影响可能会澄清成病因.
研究的目的:
- 调查多基因分数对冲动性领域与早期物质使用启动的差异预测关联.
- 探索冲动性在物质参与的病因学中的作用.
主要方法:
- 利用了来自欧洲祖先的青少年大脑认知发展研究 (n=4,808) 的数据.
- 对UPPS-P冲动性领域 (寻求感觉,缺乏预谋/坚持,负面/积极的紧迫性) 的多基因分数 (PGS) 与15岁时开始使用物质之间的估计关联.
- 采用调解模型来评估童年冲动性是否调解PGS和物质使用初始化之间的联系.
主要成果:
- 感觉寻求多基因分数 (SS-PGS) 显著预测了任何物质和酒精使用的开始 (ORs > 1.10,pFDR < 0.05).
- 缺乏坚持 (LPERSEV) 和紧迫性 (NU/PU) PGS 显示名义上的关联与酒精和尼古丁使用的开始,分别.
- 对于LPREMED-PGS或大麻使用启动没有发现任何显著的关联. 测量的冲动性解释了5-9%的PGS物质使用关联.

Attention-Deficit/Hyperactivity Disorder
743
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....

Human Genetics
1.4K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Drug Abuse and Addiction: Pharmacological Phenomena
1.1K
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...

Behavioral Genetics and Its Designs
1.0K
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.

Substance Use Disorders Affecting Sleep
398
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 Dependence
1.6K
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...
