據(jù)據(jù)路透社3月8日?qǐng)?bào)道，英國(guó)牛津大學(xué)發(fā)表在《自然》雜志上的一項(xiàng)研究表明，新冠病毒可能會(huì)導(dǎo)致大腦萎縮，患者大腦中控制情緒和記憶區(qū)域的灰質(zhì)可能會(huì)因此減少。

COVID-19 can cause the brain to shrink, reduce grey matter in the regions that control emotion and memory, and damage areas that control the sense of smell, an Oxford University study has found.



 
研究人員在當(dāng)天發(fā)表的研究報(bào)告中表示:“有強(qiáng)有力的證據(jù)表明，感染新冠病毒導(dǎo)致大腦相關(guān)的異常。”  

"There is strong evidence for brain-related abnormalities in COVID-19," the researchers said in their study.

據(jù)報(bào)道，這項(xiàng)研究涉及785名研究對(duì)象，年齡在51歲-81歲之間，研究人員對(duì)他們進(jìn)行了兩次腦部掃描，相隔時(shí)間平均為141天。其中有401人在此期間感染了新冠病毒。

The peer-reviewed study, published in the Nature journal, investigated brain changes in 785 participants aged 51–81 whose brains were scanned twice, including 401 people who caught COVID between their two scans. The second scan was done on average 141 days after the first scan.

研究人員對(duì)比發(fā)現(xiàn)，新冠病毒導(dǎo)致的大腦灰質(zhì)減少和組織受損程度，可能大于未感染者自然出現(xiàn)的此類(lèi)情況。在兩次掃描間，新冠肺炎患者額外失去了0.2%至2%的大腦灰質(zhì)，與嗅覺(jué)有關(guān)的大腦區(qū)域組織受損。

研究還發(fā)現(xiàn)，一些新冠患者還會(huì)出現(xiàn)包括注意力、專(zhuān)注力、信息處理速度下降和記憶力受損等情況。

 

Even in mild cases, participants in the research showed "a worsening of executive function" responsible for focus and organising, and on an average brain sizes shrank between 0.2% and 2%.

Studies have found some people who had COVID suffered from "brain fog" or mental cloudiness that included impairment to attention, concentration, speed of information processing and memory. 

研究人員表示，這些影響是否可以部分逆轉(zhuǎn)，或者是否會(huì)長(zhǎng)期存在，還需要進(jìn)一步調(diào)查。

Whether the impact could be partially reversed or if they would persist in the long term needed further investigation.

報(bào)道指出，這項(xiàng)研究是在阿爾法變異毒株為英國(guó)主要流行毒株時(shí)進(jìn)行的，因此無(wú)法體現(xiàn)德?tīng)査儺惗局陮?duì)病人腦部的影響。

The study was conducted when the Alpha variant was dominant in Britain and is unlikely to include anyone infected with the Delta variant.

研究人員也沒(méi)有說(shuō)明接種新冠疫苗是否會(huì)對(duì)這些現(xiàn)象產(chǎn)生任何影響，但英國(guó)衛(wèi)生安全局在上個(gè)月表示，綜合此前的15項(xiàng)研究發(fā)現(xiàn)，接種疫苗的人群出現(xiàn)新冠感染后遺癥的可能性約為未接種者的一半。

The researchers did not say if vaccination against COVID had any impact on the condition but the UK Health Security Agency said last month that a review of 15 studies found that vaccinated people were about half as likely to develop symptoms of long COVID compared with the unvaccinated.
