海马肿胀与长期和慢性疲劳患者的记忆和浓度问题有关

澳大利亚格里菲斯大学的研究人员使用超高的磁共振成像（MRI）机器来分析多长时间和肌动脑脊髓炎 - 也称为慢性疲劳综合征（CFS） - 同样会影响大脑结构

People with Long Covid and chronic fatigue tend to have swelling in an area of the brain linked to memory and concentration, a study said Tuesday.

一项研究周二说，患有长期和慢性疲劳的人往往会在与记忆和集中度有关的大脑区域肿胀。

Researchers from Griffith University in Australia used an ultra-high-field magnetic resonance imaging (MRI) machine to investigate how Long Covid and myalgic encephalomyelitis -- also known as chronic fatigue syndrome (CFS) -- impact brain structure in a similar way.

澳大利亚格里菲斯大学（Griffith University）的研究人员使用超高的磁共振成像（MRI）机器来研究互联性和肌动脑脊髓炎多长时间 - 也称为慢性疲劳综合征（CFS） - 以类似的方式影响大脑结构。

The research, published in the scientific journal PLOS ONE, involved 17 Long Covid patients, 29 CFS patients, and 15 people with neither condition, Xinhua news agency reported.

据新华社报道，这项研究发表在《科学杂志》一书中，涉及17名长期兴趣患者，29名CFS患者和15人既不状态又有病人。

The team identified significantly larger hippocampus volume in Long Covid and CFS patients compared to healthy individuals.

与健康个体相比，该小组在长期和CFS患者中确定了海马体积明显更大。

The hippocampus is a small but important part of the brain that helps with learning and converting short-term memories into long-term memories, as well as verbal and spatial memory.

海马是大脑的一个小但重要的部分，可帮助学习和转化短期记忆转化为长期记忆以及言语和空间记忆。

The study found that hippocampal volume was similar among Long Covid and CFS patients and that hippocampal swelling was linked to symptom severity in both groups.

该研究发现，长期的共同和CFS患者的海马体积相似，海马肿胀与两组的症状严重程度有关。

Kiran Thapaliya, lead author of the new study, said that the findings show that hippocampal impairment in Long Covid and CFS patients "may play a significant role in cognitive difficulties such as memory problems, difficulty concentrating, and delayed responses to questions or conversations."

这项新研究的主要作者基兰·塔帕利亚（Kiran Thapaliya）说，这些发现表明，长期相互企业和CFS患者的海马受损“可能在认知困难中起着重要作用，例如记忆问题，集中精力和对问题或对话的延迟回答延迟。”

He said that the larger volume could be caused by neurogenesis -- the process by which new cells are formed in the brain -- or by a virus in the brain.

他说，较大的体积可能是由神经发生引起的 - 大脑中新细胞形成新细胞的过程或大脑中的病毒。

Further, the study also found the size of the hippocampus was associated with symptom severity in both patient groups.

此外，研究还发现，海马的大小与两个患者组的症状严重程度有关。

People with high hippocampus volume had “impaired concentration, unrestorative sleep, pain, and fatigue," Thapaliya said.

Thapaliya说，海马体积高的人“浓度受损，无情的睡眠，疼痛和疲劳”。

The researchers noted that the overlap between CFS and Long Covid may pave the way for exploring potential treatments for both conditions.

研究人员指出，CFS和长期共同的重叠可能为探索两种情况的潜在治疗铺平道路。
