概括

超直流刺激 (tDCS) 有效治疗抑郁症,但结果各不相同. 这项研究发现,准前极和轨道前皮层,而不仅仅是L-DLPFC,通过考虑个体大脑解剖学来提高tDCS的有效性.

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.
医疗工程医学工程

背景情况:

通过调节皮质活动,超直流刺激 (tDCS) 显示出治疗抑郁症的前景.
在tDCS抑郁症治疗中不一致的结果与可变的电极安装和电场强度有关.
当前的元分析往往忽略了组装和电场分布对治疗变异性的影响.

研究的目的:

为了研究电场分布,安装参数和抑郁症tDCS的临床结果之间的关系.
确定特定的大脑区域和电场强度与抑郁症中积极的tDCS反应相关.
通过纳入头部模型中的解剖学差异来解决实验间的变异性.

主要方法:

一个元分析,将临床结果 (效果大小) 与电场强度相关联.
利用8种不同的头部模型来模拟29项研究 (1766名患者,2000-2023) 的电场分布.
分析了考虑到组装异质性和个体解剖变异性的数据.

主要成果:

tDCS对抑郁症具有显著的整体影响 (Hedge的g=0.66).
与预期的L-DLPFC (BA 46) 准相反,电场显示了额叶的广泛分布,具有显著的异质性.
在BA 10,BA 11和前部BA 46中发现电场强度与临床结果之间的相关性.

结论:

针对前极前额叶皮层 (BA 10,BA 11) 和轨道前额叶皮层 (前面的BA 46) 可能对抑郁症中的tDCS更有效.
个体解剖学变异性和精确的电场建模对于优化tDCS治疗至关重要.
强调需要模拟导向,个性化tDCS试验用于抑郁症管理.

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...
