Even mild forms of COVID-19 can cause a reduction in brain size, according to scientists in the UK.

根據(jù)英國科學家研究發(fā)現(xiàn)，即使是新冠輕癥也能造成大腦縮小。

They scanned the brains of over 400 people who had previously had COVID-19, most of them mild cases.

科學家們掃描了超過400多名新冠康復(fù)者的大腦，其中絕大部分是輕癥。

They found that the overall brain size in infected participants had shrunk between 0.2 and 2 percent, and patients experienced losses in grey matter in the?olfactory?areas, linked to smell, and regions linked to memory.

總的來說，他們發(fā)現(xiàn)這些參與研究的新冠康復(fù)者大腦縮小了0.2%-2%，其中，患者損失的灰色神經(jīng)組織與（腦部）嗅覺區(qū)、記憶區(qū)域相關(guān)。

The apparent effect of this was that those who had recently recovered from COVID-19 found it a bit harder to perform complex mental tasks.

這造成的顯著影響是，那些近期克服新冠的康復(fù)者發(fā)現(xiàn)自己完成復(fù)雜的腦力作業(yè)變得困難了一些。

The study was published on Monday in the science journal Nature. Lead author of the study Professor Gwenaelle Douaud, from Oxford University’s Wellcome Centre for Integrative Neuroimaging said: “We were looking at essentially mild infection, so to see that we could really see some differences in their brain and how much their brain had changed compared with those who had not been infected was quite a surprise.” - ARAB NEWS

該研究成果于周一發(fā)布在科學期刊《自然》上。該研究的第一作者是Gwenaelle Douaud教授，來自于哈佛大學研究綜合性神經(jīng)影響的威康中心，他表示：我們觀察的基本都是新冠輕癥患者，所以當可以切實看到他們的大腦有一些不同以及與那些沒有被感染的人相比，大腦發(fā)生了多大程度的變化的時候，這是相當令人驚訝的。（阿拉伯新聞報）
