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.
医疗器械医疗器械

背景情况:

侵入性迷走神经刺激 (iVNS) 是一种已批准用于重大抑郁障碍 (MDD) 的治疗方法.
对IVNS机制的有限理解阻碍了治疗分层和响应预测.
afferent 阴核向涉及情绪处理的大脑区域投射,表明一个潜在的治疗目标.

研究的目的:

为了调查急性跨静脉迷走神经刺激 (taVNS) 是否可以改善MDD患者的情绪处理.
评估taVNS对面部情绪识别和自我报告的情绪状态的影响.

主要方法:

进行了一项随机对照试验,有52名患有MDD的参与者和44名对照.
参与者在taVNS和假刺激期间执行了面部情绪识别任务.
使用线性混合效应模型来分析taVNS对情绪处理的影响.

主要成果:

在所有参与者中都观察到情绪识别的基线负偏差.
急性taVNS显著提高了检测积极面部表情的准确性.
taVNS减少了负面情绪状态的报告,对积极的情绪状态产生了群体依赖的影响.

结论:

急性横静脉迷走神经刺激 (taVNS) 影响情绪处理,无论诊断如何.
这些急性影响可以作为对长期taVNS治疗结果的预测标记.
需要进一步的研究来验证taVNS作为长期治疗效果的预测标志物.
