概括
重复的COVID-19感染可能会导致严重的抑郁症并改变白质 (WM) 的完整性. 这项研究发现,在多次感染后患有严重抑郁症的患者中,WM完整性下降,这凸显了心理支持的需要.
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.
- 传染性疾病 传染性疾病
背景情况:
- 长期冠状病毒疾病2019 (COVID-19) 可以动态地改变白质 (WM) 完整性.
- 在多次COVID-19感染后严重抑郁症中白质变化的研究缺乏.
- 这项研究调查了两次COVID-19感染后经历严重抑郁症的患者的长期WM变化.
研究的目的:
- 为了评估COVID-19感染后抑郁症患者的长期白质 (WM) 变化.
- 为了比较两次感染后患有严重抑郁症的患者和一次感染后患有轻度/中度抑郁症的患者之间的WM完整性.
- 分析心理症状和WM参数之间的相关性.
主要方法:
- 前性研究包括27名患有两次COVID-19感染后重度抑郁症的患者和28名患有轻度/中度抑郁症后一次感染的对照.
- 对抑郁,焦虑和失眠的心理评估是在感染后3-6个月进行的.
- 扩散张力成像 (DTI) 用于计算分数异构性 (FA) 和扩散度;分析相关性.
主要成果:
- 两组之间没有年龄,性别或教育方面的显著差异.
- 患者组表现出明显更高的抑郁,焦虑和失眠得分 (P<0.001).
- 在患者组中观察到皮质脊髓通道,前丘脑辐射和上纵向囊 (P<0.05) 的FA值下降.
- 心理评分与这些WM区域的FA值负相关 (r=-0.355到-0.570,P<0.01).
结论:
- 重复的COVID-19感染与患有严重抑郁症的患者的白质 (WM) 完整性损伤有关.
- 研究结果表明,COVID-19相关抑郁症的潜在机制涉及WM损伤.

Long-term Depression
2.5K
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.
