概括

与健康个体相比,阿片类药物使用障碍 (OUD) 患者表现出抑制控制受损和对药物线索的反应性增加. 这些上下控制的缺陷和增加的暗示灵敏度有助于OUD中持续的成行为.

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.
成研究研究成研究

背景情况:

阿片类药物使用障碍 (OUD) 是一种慢性复发性疾病,其特征是强迫性寻找药物.
了解OUD中抑制性控制缺陷的神经支柱对于开发有效治疗非常重要.
以前的研究表明,在OUD患者中,认知功能发生改变,包括抑制控制.

研究的目的:

与健康对照者 (HCs) 相比,研究OUD男性患者的抑制控制机制.
在Go-NoGo任务中使用事件相关潜力 (ERP) 检查抑制控制的神经相关物.
评估与药物相关的线索对OUD认知过程的影响.

主要方法:

招募了30名男性OUD患者和30名匹配的男性HC.
使用了修改后的Go-NoGo任务,结合了与片有关的和中性线索.
监控与事件相关的潜能 (ERP),以评估任务执行期间的神经活动.

主要成果:

OUD患者表现出更慢的反应时间和更多的调试错误,表明抑制控制受损.
健康对照组表现出显著的NoGo N2效应,表明抑制性处理,而OUD患者没有这种效应.
OUD受试者表现出减弱的NoGo N2和P3振幅,这表明冲突解决和后期抑制方面的缺陷,特别是在对片线索的反应中. 观察到对片线索的注意力偏差增强 (较大的N1幅度).

结论:

研究结果支持成的双过程模型,突出显示上下控制受损和OUD中药物暗示反应性增加.
抑制控制的缺陷和提升的暗示反应性与上行为持续存在有关.
建议针对抑制控制和提示诱导的渴望的治疗干预措施用于OUD康复.

关键词:

注意力偏差是一种注意力偏差.与事件相关的潜力与事件相关的潜力这是一个Go-NoGo任务.抑制性控制是一种抑制性控制.片类药物使用障碍.与片有关的线索.

Opioid Receptors: Overview

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!
