最常见的症状COVID-19include fever, cough, shortness of breath, and fatigue. However,neurological symptoms- 那些影响您的大脑和神经系统的人 - 报告 25 percent 开发共vid-19的人。

Lingering “brain fog” is one neurological symptom that people with COVID-19 commonly report. In some cases, brain fog, or cognitive impairment, can last many months after the disease has passed.

在本文中，我们将仔细研究Covid-19为什么在某些人中引起大脑雾，多么普遍以及何时为这些神经系统获得帮助。

脑雾不是医学诊断。相反，这是一个通用术语，用于描述精神慢，模糊或间隔的感觉。

Symptoms of brain fog can include:

大多数人偶尔​​会经历大脑雾期。经过一夜睡眠不足或承受很大的压力，您可能会感到精神迟钝。

但是有些有COVID-19的人报告了大脑雾持续数周甚至在其他症状（例如咳嗽，疲劳或发烧）之后的几个月后，已经消失了。

Researchers are still investigating the potential cause of brain fog in people who’ve had COVID-19. It’s thought that both physiological and psychological factors may play a role.

人们认为，新的冠状病毒（称为SARS-COV-2）通常通过与感染的人密切接触而传播。该人的呼吸液滴可以通过鼻子，嘴或眼睛进入您的身体。

Once in your system, the coronavirus enters cells through an enzyme called angiotensin-converting enzyme 2 (ACE2) receptor. The virus is neuro-invasive, meaning that it can enter your brain tissue.

很多的 case studies 已经发现，有些与19 Covid-19的人发生了并发症，例如改变意识或脑病。Encephalopathy是指大脑损害或疾病的一般术语。

一个 study from January 2021 found increased levels of inflammatory cytokines in the fluid surrounding the brains of people weeks after their COVID-19 infection. Cytokines are molecules produced by your immune system that encourage inflammation.

大脑的炎症阻碍了神经元相互交流的能力。这可能是导致大脑雾的因素之一。

研究人员也有 identified Covid-19之后，海马和大脑其他区域的微结构变化。他们认为这些变化也可能导致认知障碍。

Other factors that may contribute to brain fog

一个s mentioned above, inflammation in and around your brain may contribute to brain fog. However, there are other ways that COVID-19 may indirectly lead to brain fog as well.

一些可能的因素包括：

研究人员仍在努力了解脑大脑在19岁的人中有多普遍。

One recent 分析 表明，有7.5％至31％的人经历了精神状态的改变，作为19 Covid-19的症状。但是，该估计基于小型研究，可能不适用于较大的人群。

一个nother recent study reports that neurological symptoms could be more widespread than originally thought and may occur in up to 69 percent of people who’ve had severe illness with COVID-19.

目前，目前尚不清楚为什么有些人会发展大脑雾，而其他人则没有。患有严重案例Covid-19的人似乎处于 higher risk for developing neurological symptoms than people with mild disease.

严重的与大脑有关的并发症 如delirium，，，，发作，，，，and inflammation of the brain and surrounding tissues are most common in critically ill patients.

It’s still not clear how long brain fog typically lasts after COVID-19. Some people report brain fog that lingers for weeks or months after their respiratory symptoms have gone away.

一个 study 2020年12月出版的发现，约有28％的人在Covid-19的住院后超过100天患有挥之不去的浓度问题。

In another study ,研究人员发现了一群60 patients who’d recovered from COVID-19, 55 percent still had neurological symptoms 3 months after their illness. These symptoms included:

  • 情绪变化
  • fatigue
  • headaches
  • visual disturbances

截至目前，Covid-19引起的最佳脑雾的治疗方法是采用健康的习惯。如果您要处理持续的大脑雾，以下技巧可能有助于提高您的心理功能。

  • 睡个好觉。Getting good quality sleep can help your body repair and recover.
  • Get regular exercise.Physical activity isn’t only beneficial to your heart and lungs, it’s also a great way to boost your brain function.
  • 吃好。Try to eat a均衡，健康饮食为了给您的身体，它需要恢复健康所需的营养。
  • 一个void tobacco and alcohol.Staying away from tobacco products and alcohol can help minimize inflammation in your brain.

研究人员正在继续研究类固醇对减少大脑炎症的潜在益处，这可能导致认知变化。

如果您的心理症状足够严重，可以干扰您的日常生活，或者几周后没有改善，这是一个好主意。

If you have COVID-19, it’s important that you seek immediate medical attention if you have any of the following symptoms:

  • 呼吸困难
  • ongoing pain or pressure in your chest
  • rapid heart rate
  • new mental confusion
  • trouble staying awake or difficulty waking
  • 蓝色指甲or嘴唇

有些患有COVID-19的人报告说，脑部雾气持续了数周或几个月。人们认为，大脑的生理变化和心理因素的结合可能会导致这种情况。

研究人员仍在试图理解为什么有些人会出现Covid-19的神经系统症状，而另一些人则没有。如果您有19岁，并且存在挥之不去的认知问题，这些问题会影响您清楚思考的能力，请确保跟进医生。
