概括

耐治疗抑郁症 (TRD) 涉及改变的大脑连接. 电疗法 (ECT) 改善了前端对面网络 (FPN) 和语言网络 (LN) 的功能连接 (FC),这表明其抗抑郁作用的机制.

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:

耐治疗抑郁症 (TRD) 是一个重大的临床挑战.
异常的功能连接性 (FC) 涉及到TRD,但前端对象网络 (FPN) 和语言网络 (LN) 的模式需要进一步阐明.
电疗法 (ECT) 对TRD非常有效,但其神经生物学机制仍然不太清楚.

研究的目的:

在电治疗 (ECT) 之前和之后,研究治疗耐药性抑郁症 (TRD) 患者的前对对面网络 (FPN) 和语言网络 (LN) 的功能连接 (FC) 模式.
探索TRD中FC变化的基础的神经成像-转录关联.
阐明ECT抗抑郁作用的潜在机制.

主要方法:

基于种子的功能连接 (FC) 分析使用静止状态fMRI数据.
包括72名TRD患者 (52名完成随访) 和63名健康对照 (HC).
进行了神经成像-转录关联分析.

主要成果:

在基线时,TRD患者在FPN内以及FPN/LN和体运动网络 (SMN) 和默认模式网络 (DMN) 之间表现出降低的FC.
在ECT后,显著的症状减少与FPN内和FPN/LN和DMN之间增加的FC相关.
与基线FC改变相关的基因在离子通道活性和突触功能方面得到了丰富.

结论:

TRD的特点可能是认知,感官和自我参考大脑系统之间的功能整合减少.
ECT的抗抑郁作用似乎涉及高阶认知区域内以及认知和自我参考网络之间的FC调节.
这些调制可能支持TRD患者治疗ECT的情绪和认知调节的增强.

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...
