研究发现得c19失去嗅觉的人长期认知水平减低

我是1月得的，到现在我觉得我嗅觉没有恢复好。估计是好不了了

It all makes sense, since olfactory bulb is the only cranial nerve actually belongs to central nervous system. It directly leads to midbrain, right next to hippocampus (in charge of memory), and amygdala (emotion). Loss/change of smell is because of the attack or damage from the viral infection. Theoretically, virus can enter the brain through olfactory bulb. Depending on the severity of the infection and how strong your innate immunity on your nasal mucosa, it could decide how spread out infection is. Once any infection gets in the brain, it's always harder to get rid than the rest of the body.

我嗅觉还行，味觉不太对，吃不出肉味道，水果只能吃出甜不甜也吃不出具体味道。基本上除非是草莓这种有气味的水果，一般的我吃着味道是一样的。

我擦，我现在在厕所都闻不到臭味，是不是我以后要变傻子了...但是新冠好像治好了我的过敏性鼻炎, 现在闻啥都没事

发帖写covid后遗症麻烦把苗没苗过写上，否则就是刷流氓……

难道不是味觉么？周围阳过得，很多是细微味觉丢失的

伤害了脑神经

嗅觉味觉丧失就是病毒入脑搞破坏了，还是戴口罩吧~

我几乎在新冠开始的时候，开始有一个古怪的症状，只要我闻到了焦糊味，比如camping的篝火味，就会接连几个礼拜总能闻到这种味，当然其实并不存在。

味觉理论上不如嗅觉有predictive value，决定味觉的facial nerve算是周边神经，离大脑比较‘远’，而且确实以前有研究来拿嗅觉来predict cognitive function的

打不打疫苗都会感染，感染了就有丧失嗅觉long covid的风险。这study里有vaccination status information，但唯一predict cognitive function in post covid sequalae就是嗅觉改变。
