概括
在左背侧前额叶皮层进行重复性横磁性刺激 (rTMS) 显著减少了吸烟,而不是准奖励回路. 这表明加强执行控制是rTMS辅助戒烟的关键.
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 药物 药物 药物 药物
背景情况:
- 重复性横磁性刺激 (rTMS) 是一个有前途的戒烟帮助.
- 对于烟草使用障碍 (TUD) 的rTMS疗效背后的神经机制尚未完全理解.
- 这项研究调查了rTMS是否增强执行控制或抑制奖励活动以减少吸烟.
研究的目的:
- 为了比较刺激性和抑制性rTMS对TUD患者不同脑电路的影响.
- 为了确定rTMS是否通过改善执行控制或调节奖励处理来减少吸烟.
- 为了阐明rTMS用于戒烟的神经机制.
主要方法:
- 这是一项双盲,模拟控制试验,涉及46名TUD患者.
- 参与者接受了15次fMRI指导的,E场剂量的rTMS:假的,在左侧脊侧前额叶皮层 (L-DLPFC) 上进行10 Hz,或在左侧中间轨道前额叶皮层 (L-mOFC) 上进行1 Hz.
- 主要结局包括减少每天吸烟 (CPD) 和在fMRI扫描上BOLD活动的变化.
主要成果:
- 与1赫兹L-mOFC和假装组相比,10赫兹L-DLPFC组显示出明显更大的CPD减少 (分别为-11.14和-4.92和-6.43).
- rTMS到L-DLPFC增加了前额活动和减少了轨道前额活动.
- 减少CPD与增强的L-DLPFC激活相关.
结论:
- 通过10 Hz rTMS在L-DLPFC上加强执行控制,比调节奖励电路更有效地减少吸烟.
- 加强奖励处理的前额调节似乎是rTMS诱导的戒烟的关键机制.
- 这些发现支持L-DLPFC刺激作为TUD治疗的有针对性的方法.

Blinding
3.0K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
