We have witnessed COVID-19 affecting our lives at such a deep level. There are new variants coming around which gives chills down our spine. In this viral infection, it was observed that most of the people had shortness of breath, fatigue, cough and fever. People are unaware of the fact that these are also neurological symptoms of brain fog. Brain fog is not a disease but just a condition which affects your cognitive functions and results to have some lingering effects on the body. In last few months those who knew got COVID-19 also had symptoms linked to brain fog, this reveals that there is some connection between these two condition. To know about this topic in depth, we will discuss about link between corona virus and brain fog, by help of an expert.

How can COVID-19 affect brain fog?

It is not that brain fog particularly needs to be administered under category of COVID symptoms. Our expert Dr. Tanu Chowdhury, Clinical Psychologist from Healthcare Hospital, Lucknow, explains that brain fog can occur as a result of corona virus infection. This may not be necessary but symptoms are similar in some cases. Brain fog is a neurological condition that also affects cognitive and mental health.


In the previous months where the virus created havoc among the people, it raised cases of anxiety and fatigue. Both anxiety and fatigue result to more problems such as shortness of breath and decrease in immunity levels. Because of this the rate of infection of corona virus also increased and people found it hard to recover from it. 

Corona virus has been observed to impact your cognitive health and thus it may make you vulnerable to brain fog. However an important point is, brain fog affected by COVID-19 also goes away after few months as the symptoms of corona virus are healed. 

Symptoms of COVID-19 Brain fog

Basic symptoms of brain fog remain the same, here we are about to know about the mixed symptoms which COVID-19 infected people might witness if they are having brain fog. Symptoms of this condition includes-

  • Memory problems
  • Lack of mental clarity
  • Headaches
  • Confusion
  • Poor concentration

Most of people suffering from COVID-19 get these symptoms but are unaware of it because the fear of infection penetrates inside them. You must know that brain fog during COVID is not permanent; it may come occasionally and result to mental sluggish or poor sleep. Therefore, the best way to reduce symptoms is to sleep and avoid stress.


Why COVID-19 causes Brain Fog?

There are many researches still going on to find about the cause linked to brain fog with corona virus. Since corona virus is comparatively new, therefore not much is known about it. Also different variants have shown different symptoms over the time which is raising concern. Therefore there are both physiological and psychological factors involved in cause of brain fog during COVID-19 infection.

The delta variant typically enters the body of another person through coming in close contact with the person. This means that there may be chances that respiratory problems might occur from that source, the virus infects your mouth, eyes and through your nose. 

Once the virus gets into your body it goes through the enzyme called angiotensin-converting enzyme 2 receptor. This is neuro-invasive virus which means it enters your brain tissue. Once it enter your brain tissue then there is little left to do, it causes complications such as altered consciousness which is a term referring to a disease in your brain. Inflammation in your brain affects your neurons which probably is the main cause of getting brain fog in COVID-19.
