概括

在基线EEG中,左前方α不对称 (FAA) 预测了对治疗耐药性抑郁症 (TRD) 的重复性跨磁刺激 (rTMS) 甲爆刺激 (TBS) 的积极反应. 这种EEG生物标志物为优化TRD治疗选择提供了一个有前途的工具.

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.
生物标志物研究生物标志物研究

背景情况:

重复性横磁刺激 (rTMS) 是治疗耐药性抑郁症 (TRD) 的关键治疗方法.
识别生物标志物来预测RTMS反应对于个性化治疗策略至关重要.
现有的脑电图 (EEG) 标记器缺乏对TBS协议的特异性.

研究的目的:

为了确定预测性电脑电图 (EEG) 生物标志物,用于在接受TRD的rTMS TBS患者的治疗结果.
调查基线EEG标志物与对TBS-rTMS的反应之间的关联.

主要方法:

在TBS-rTMS治疗之前,从46名TRD患者获得了休息状态EEG记录 (10-15分钟).
在19-21个会议中,患者在左侧脊侧前额叶皮层接受了600个刺激.
抑郁症的严重程度使用汉密尔顿抑郁症评分表和贝克抑郁症库存II进行评估.

主要成果:

与非响应者相比,在基线EEG中观察到显著较低的前额α不对称 (FAA) 值在响应者中.
由FAA指出的左前额α优势与对TBS-rTMS的积极反应有关.
发现FAA独立于患者的年龄和性别.

结论:

基线EEG前额α不对称 (FAA) 是TRD患者TBS-rTMS治疗结果的一个有前途的预测生物标志物.
美国联邦航空局可能会帮助临床医生优化TRD的治疗选择.
需要对不同种群进行进一步的研究,以验证FAA作为可靠的生物标志物.

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...

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...
