Brain Fog And COVID-19: Let’s Clear The Confusion!

Introduction

Have you ever experienced episodes in which your mind seems foggy, everything seems perplexing, and the simplest tasks, such as perusing the morning paper or answering a simple exam question, seem like a Herculean task? 

Well, this peculiar sensation may be due to brain fog! 

Brain fog is a common condition characterized by periods of perplexity, migraines, and mental cloudiness. On a cellular level, brain fog is believed to be caused by inflammation, which disrupts our delicate hormonal equilibrium. This imbalance affects the entire system and can diminish your life's quality. 

Frequent causes of brain fog include extreme tension, depression, lack of sleep, and overwork. However, brain fog has been in the news recently due to its close association with COVID-19 infection.

The purpose of this article is to define brain fog and explain why COVID-19 causes it.

Symptoms of Brain Fog

Brain fog is a term used to define the sensation of being mentally hazy, sluggish, and disoriented. These are some symptoms of brain fog that you may experience:

• Poor concentration
• Constant headaches
• Absence of proper clarity of mind
• Confusion
• Issues with memory
• Feeling as if you are detached mentally
• Mental fatigue
• Difficulty in thinking and understanding simple situations

  

What is the link between COVID-19 & Brain Fog?

There is no solid evidence explaining why COVID-19 appears to cause brain fog. However, psychological and physiological factors are believed to be at play. Once the coronavirus has invaded the system and entered the cells via the angiotensin-converting enzyme 2 (ACE2) receptor, it is able to penetrate brain tissue due to its neuro-invasive nature.

Numerous studies have shown that COVID-19 patients experience complications such as altered consciousness, brain injury, or brain disease, which are collectively referred to as encephalopathy.

High levels of inflammatory cytokine molecules, which are produced by the immune system, were detected in the fluid surrounding the brains of individuals who had recovered from COVID-19 infection a few weeks earlier, according to case studies. One of the many causes of brain fog is inflammation within the brain, which impedes the neurons' ability to communicate fully with one another. 

Brain Fog is one of the commonest Long Covid Symptoms reported.
