概括
系统性炎症和改变的大脑血流,而不是焦虑或无情,预测大抑郁症发作结果. 结合这些标志物,可以随着时间的推移改善抑郁症严重程度的预测.
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:
- 系统性炎症与主要抑郁发作 (MDE) 严重程度和治疗耐药性抑郁症 (TRD) 相相关.
- 关联炎症和抑郁症持续性的大脑机制尚不清楚.
- 需要预测抑郁症治疗结果的预测标记.
研究的目的:
- 确定临床,炎症和脑血流 (CBF) 标志物,预测6个月后MDE的结果.
- 评估结合这些标记物的综合方法的实用性.
- 探索焦虑和无情感作为预测者的作用.
主要方法:
- 60名MDE患者的长度研究.
- 使用伪连续动脉旋转标记 (pcASL) 评估抑郁症严重程度,炎症 (C-反应蛋白 - CRP) 和CBF.
- 引导弹性净回归分析用于识别预测标记.
主要成果:
- 基线抑郁症强度,剧情持续时间,CRP和特定的CBF区域 (右侧,轨道前皮层) 积极预测了抑郁症的结果.
- 其他区域的年龄,疾病持续时间和CBF (尾状核,杏仁体,中额头,腹中前额叶皮层) 是负面预测因素.
- 焦虑和快乐感并不是显著的预测因素;一个整合模型表现优于其他模型.
结论:
- 系统性炎症和情绪/奖励回路中的改变CBF是持续性抑郁症的潜在生物标志物.
- 结合临床,炎症和神经成像数据的综合方法可以提高对抑郁症严重程度变化的预测.
- 这些发现强调了系统性炎症和脑 perfusion 在抑郁症预后的重要性.

Long-term Depression
33.1K
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.
