EXTREME and incomplete oversimplification of the many complex neurological issues caused by SarsCov2, but important facet of the vaguely defined “brain fog” of Long Covid and post-acute Covid lingering symptoms.

“Neurological symptoms have been widely observed in COVID-19 patients, with many survivors exhibiting persistent neurological and cognitive impairment. New research from the University of Minnesota found that COVID-19 triggers inflammation in the brain, which is linked to many COVID-related symptoms such as fatigue and ‘brain fog.’”

UK researchers scanned the brains of 400 people before and after mild covid, compared them with controls and found:

1. greater reduction in grey matter thickness
2. greater reduction in global brain size
3. greater cognitive decline
4. greater change to primary olfactory cortex
