概括
后COVID-19状态显示减少但持续的疲劳和大脑变化感染后长达两年. 大脑的适应发生,一些异常会消失,而另一些异常会持续存在,这表明非大脑因素会影响疲劳.
科学领域:
- 神经科学是一个神经科学.
- 传染性疾病 传染性疾病
- 精神病学是一个精神病学.
背景情况:
- 后COVID-19状态影响高达10%的SARS-CoV-2感染个体,疲劳和认知功能障碍作为主要症状.
- 追踪神经心理和临床轨迹以及相关的大脑变化的纵向研究是有限的.
- 了解这些症状和大脑变化的长期演变对于有效的患者管理至关重要.
研究的目的:
- 研究COVID-19后患者在感染后两年内神经心理和临床结果的演变.
- 通过神经成像技术检查大脑结构和功能的相关变化.
- 确定影响COVID-19后症状持续或消失的因素.
主要方法:
- 这是一项多中心的纵向研究,涉及79名COVID后患者和21名健康对照.
- 对神经心理表现和感染后23个月的自我报告结果的分析.
- 休息状态功能和结构磁共振成像 (MRI) 数据的评估.
主要成果:
- 疲劳严重程度降低,但在23个月后大多数COVID后患者中仍然存在.
- 观察到广泛的大脑变化,包括大脑干,前/后中心,和边缘嗅觉网络的变化.
- 观察到自我报告疲劳的减弱及其与大脑变化的关联,住院患者的脑异常更为明显.
结论:
- 复杂的大脑适应发生在SARS-CoV-2感染后的两年内.
- 一些大脑区域表现出持久的异常,而另一些则显示出恢复的迹象.
- 临床症状和大脑变化之间的联系正在减弱,这表明补偿机制和潜在的非大脑内在因素有助于持续疲劳.

Longitudinal Studies
145
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Longitudinal Research
11.9K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

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.
