COVID-19 Leaves Its Mark on the Brain.

[Maxmars]

No one knows why some people do not totally clear the virus.  But it is not only SARS-2 that creates Post Viral Syndrome.  Scores of people have Chronic Fatigue Syndrome [CFS] from bouts with the flu, EBV, and other viruses.
Personally, I have suffered from tinnitus since a 1993 bout with the flu.

People's lives have been ruined.  Their careers in the toilet.  Relationships gone. 
They are not lying or making it up.

Some people have suffered with various types of conditions...some for years.  This is not a narrative.  This is what is left of their lives.  
Doctors send many people home with drugs to treat their ailments, basically saying it is all in their minds.

I suppose this is essentially one form of a "post viral syndrome," if that isn't already a thing. Except people's biases make it a hit or miss to discuss especially when paired with "new" diseases like COVID, heavily laden with social baggage,

I am familiar with doctors saying something is only in the patient's mind ... (and how they never discuss just how wrong they have been on more than one occasion, and even less about the fate of the patient so dismissed from treatment. But that's another story.)
