概括

与虚假治疗相比,间歇性甲基突发刺激 (iTBS) 在抑郁症中对情绪处理没有立即影响. 然而,随着时间的推移,情绪反应和大脑活动发生了变化,这表明潜在的长期益处和ACC参与治疗.

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.
医疗成像医学成像

背景情况:

抑郁症与改变的情绪处理有关.
重复性横磁刺激,包括间歇性甲基突发刺激 (iTBS),是一种新兴的抑郁症治疗方法.
这项研究调查了iTBS对抑郁症情绪预期和处理的影响.

研究的目的:

检查活跃与虚假iTBS对抑郁症患者情绪预期和处理的影响.
评估与情绪刺激相关的行为,生理和神经反应的变化.

主要方法:

42名抑郁症患者接受了活跃或假的iTBS.
在基线和四周记录了fMRI和皮肤导电性反应 (SCR).
参与者进行了情绪预测和处理任务,并收集了行为数据.

主要成果:

活跃和假 iTBS 组之间的行为,SCR 或神经活动没有显著差异.
在两组中,对积极预期的SCR增加,对负面处理的SCR减少.
杏仁体和胰岛素对负处理的反应性,以及右杏仁体对正处理的反应性下降.
活跃的iTBS增加的ACC活动与减少的无性相关.

结论:

与假的相比,活跃的iTBS并没有立即改变抑郁症中对情绪处理的行为,生理或神经反应.
随着时间的推移,观察到的变化表明假 iTBS 的正常化或部分效应.
前环皮质 (ACC) 似乎在iTBS治疗抑郁症的治疗机制中发挥作用.

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
