Have you ever experienced episodes where your mind seems fuzzy, everything seems confusing and performing the simplest of activities, such as reading the morning paper or solving a simple question in an exam, seems like a Herculean job for you?
Well, the reason behind this strange feeling can be brain fog!
Brain fog is a common phenomenon where you end up experiencing periods of confusion, headaches and brain cloudiness. When examined at the cellular level, brain fog is thought to be caused by inflammation which offsets our delicate hormonal balance. This imbalance impacts the entire system and can take a toll on the quality of your life.
Commonly, brain fog can be caused due to extreme stress, depression, lack of sleep and overworking. But lately, brain fog has been much in the news due to its close link with COVID-19 infection.

There isn’t any concrete evidence as to why COVID-19 seems to cause brain fog. However, it is believed that psychological and physiological factors are at play. Once the coronavirus has invaded the system and enters the cells through the angiotensin-converting enzyme 2 (ACE2) receptor, the virus can also enter the brain tissue due to its characteristic of being neuro-invasive.
Many studies conducted have revealed that those who have suffered from COVID-19 experience complications such as altered consciousness or brain damage or brain disease which are referred to by the general term encephalopathy.
Case studies showed that high levels of inflammatory cytokine molecules, which are produced by immunity, were found to be present in the fluid that surrounds the brains of people who had recovered from COVID-19 infection probably a few weeks prior. One of the many factors of brain fog is inflammation within the brain which obstructs the ability of the neurons to communicate completely with each other.
