概括
微剂量 lysergic acid diethylamide (LSD) 在治疗主要抑郁症 (MDD) 方面表现有前途. 这项研究发现微剂量LSD是安全和可行的,显著减少抑郁症症状. 需要进一步的随机试验.
科学领域:
- 精神病学是一个精神病学.
- 神经科学是一个神经科学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 大型抑郁症 (MDD) 影响全球5%的人口,需要新的治疗方法.
- 经典的迷幻药正在成为各种心理健康状况的潜在治疗方法.
- 以前的研究表明,迷幻药可能具有治疗效益,但对MDD微量剂量的数据有限.
研究的目的:
- 评估8周微剂量lysergic acid diethylamide (LSD) 治疗主要抑郁症 (MDD) 的可行性和耐受性.
- 评估重复微剂量LSD的安全性.
- 探索微剂量LSD在减少抑郁症状方面的初步疗效.
主要方法:
- 一个开放标签的2A期试验 (LSDDEP1),涉及19名患有MDD的参与者.
- 参与者在8周内接受了16剂微剂量的LSD (8-20微克每周两次).
- 耐受性通过戒断率,可行性通过临床上诊,安全性通过不良事件和临床措施来评估. 抑郁症使用蒙哥马利-阿斯伯格抑郁症评分表 (MADRS) 进行测量.
主要成果:
- 没有观察到严重的不良事件或安全措施的显著临床变化.
- 一名参与者因焦虑而退出;所有预定的访问都参加了,表明可行性和耐受性良好.
- 在干预结束时,MADRS得分下降了59.5%,持续了六个月. 他们还注意到焦虑,反,压力和生活质量的改善.
结论:
- 微剂量LSD似乎是安全的和可行的治疗中度抑郁症.
- 这项研究提供了微剂量LSD显著抗抑郁作用的初步证据.
- 需要进一步的随机对照试验来证实这些发现并确定疗效.

Depressive Disorders: MDD and Dysthymia
606
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Long-term Depression
3.1K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
