概括

在患有严重抑郁症的成年人中,添加D-环素与间歇性甲爆刺激 (iTBS) 快速降低了自杀念头和隐性自杀风险. 这种组合疗法对治疗抑郁症和减轻自杀风险充满希望.

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.
药理学药理学是指药理学的学科.

背景情况:

大型抑郁症 (MDD) 是自杀的主要原因.
间歇性甲型突发刺激 (iTBS) 是一种用于治疗耐药抑郁症的非侵入性脑刺激.
作为NMDA受体激动剂的D-cycloserine可能会增强抗抑郁药的效果,但其对自杀风险的影响尚不清楚.

研究的目的:

研究D-cycloserine与iTBS结合对MDD成年人的自杀念头和隐性自杀风险的影响.
为了比较iTBS与D-cycloserine与iTBS与安慰剂在减少自杀念头和隐性自杀风险方面的疗效.

主要方法:

进行了两项临床试验:一项开放性试验 (n=12) 和一项随机的安慰剂对照试验 (RCT,n=50).
使用计算机化的死亡/自杀隐性关联测试 (IAT) 来测量隐性自杀风险.
用蒙哥马利-阿斯伯格抑郁评分表 (MADRS) 评估抑郁症状和自杀念头.

主要成果:

开放标签iTBS与D-cycloserine显著降低了自杀念头和隐性自杀风险.
使用D-环素的iTBS在减少自杀念头和死亡/自杀IAT得分方面优于安慰剂的iTBS.
单剂量单独的D-环素并没有影响隐性自杀风险.

结论:

附加的D-环素与iTBS是减少抑郁症患者自杀念头的有希望的策略.
这种组合疗法也可能降低隐性自杀风险,为抑郁症中预防自杀提供了一种新的方法.

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...

Cognitive Therapy

Cognitive Therapy

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
