海馬腫脹與長期和慢性疲勞患者的記憶和濃度問題有關

澳大利亞格里菲斯大學的研究人員使用超高的磁共振成像（MRI）機器來分析多長時間和肌動腦脊髓炎 - 也稱為慢性疲勞綜合徵（CFS） - 同樣會影響大腦結構

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.

一項研究週二說，患有長期和慢性疲勞的人往往會在與記憶和集中度有關的大腦區域腫脹。

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.

澳大利亞格里菲斯大學（Griffith University）的研究人員使用超高的磁共振成像（MRI）機器來研究互聯性和肌動腦脊髓炎多長時間- 也稱為慢性疲勞綜合徵（CFS） - 以類似的方式影響大腦結構。

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.

據新華社報導，這項研究發表在《科學雜誌》一書中，涉及17名長期興趣患者，29名CFS患者和15人既不狀態又有病人。

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

與健康個體相比，該小組在長期和CFS患者中確定了海馬體積明顯更大。

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.

海馬是大腦的一個小但重要的部分，可幫助學習和轉化短期記憶轉化為長期記憶以及言語和空間記憶。

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.

該研究發現，長期的共同和CFS患者的海馬體積相似，海馬腫脹與兩組的症狀嚴重程度有關。

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."

這項新研究的主要作者基蘭·塔帕利亞（Kiran Thapaliya）說，這些發現表明，長期相互企業和CFS患者的海馬受損“可能在認知困難中起著重要作用，例如記憶問題，集中精力和對問題或對話的延遲回答延遲。”

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.

他說，較大的體積可能是由神經發生引起的 - 大腦中新細胞形成新細胞的過程或大腦中的病毒。

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

此外，研究還發現，海馬的大小與兩個患者組的症狀嚴重程度有關。

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

Thapaliya說，海馬體積高的人“濃度受損，無情的睡眠，疼痛和疲勞”。

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

研究人員指出，CFS和長期共同的重疊可能為探索兩種情況的潛在治療鋪平道路。
