Speaking with Neo Science Hub said, “Dr. Shiva Kumar R. (Senior Consultant – Neurology & Epileptology, Sakra World Hospital Bengaluru)
While not many are aware of what brain fog is, it is essential to understand that brain fog is not a medical diagnosis but a general term used to describe the feeling of being mentally slow, fuzzy or spaced out. 
Memory problems, lack of mental clarity, poor concentration, headaches, confusion are some of the common signs of brain fog. One may have faced brain fog and felt mentally sluggish after a poor night’s sleep or under quite a bit of stress”.

It could be attributed to both physiological and psychological factors. Covid-19 virus, it enters cells via an enzyme known as angiotensin-converting enzyme 2 (ACE2) receptor. This virus is neuro-invasive in nature which means it can seep inside one’s brain tissue. As a result, several people who get infected by Covid develop altered consciousness or encephalopathy that refers to damage to the brain in general. 

Also, a latest study found increased levels of inflammatory cytokines in the fluid surrounding the brain of those who have been affected by Covid and the levels remain high for weeks after the Covid-19 contraction. Cytokines which are molecules generated from the immune system encouraging inflammation prevent the ability of the neurons to communicate with each other, thereby leading to brain fog.  The brain fog may last up to several weeks and months post Covid-19 infection and its various symptoms among Covid-19 patients post recovery include mood changes, fatigue, headaches, visual disturbances, etc.
