COVID-related loss of smell tied to changes in the brain | CIDRAP
“On MRI conducted during the game, loss of smell was associated with decreased functional activity during decision-making, loss of white-matter integrity, and thinning of the outer layer of the cerebrum in the parietal regions (responsible for processing sensory input, understanding spatial relationships, and how to navigate).”

Brain effects of mild COVID-19 in healthy young adults: A pilot study
Brain effects of mild COVID-19 in healthy young adults: A pilot study
“Our pilot data suggests that mild COVID-19 may result in brain pathology and impact neurocognitive function in younger adults in a manner parallel to prior findings in older individuals. Though findings may not generalize to other SARS-CoV-2 variants, larger longitudinal studies of mild COVID-19 should be undertaken to understand the potential clinical implications of these findings over the longer term.”

Study uncovers the basis of COVID-19-related brain fog | University of Minnesota

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.’”

Patients recovering from COVID-19 who presented with anosmia during their acute episode have behavioral, functional, and structural brain alterations
Patients recovering from COVID-19 who presented with anosmia during their acute episode have behavioral, functional, and structural brain alterations
: “Patients who presented with anosmia exhibited more IMPULSIVE alternative changes…Anosmia correlated with brain measures, including decreased functional activity during the decision-making task, thinning of cortical thickness in parietal regions, and loss of white matter integrity.”

SARS-CoV-2 is able to reach CNS of COVID-19 patients, infect astrocytes,and impair neuronal function/viability, contributing to the alterations of brain structure thereby resulting in neurocognitive/neuropsychiatric dysfunctions.
