Olfactory Dysfunction and Its Relationship with Neurological Conditions and COVID-19 | Nature Research Intelligence

How COVID Might Sow Chaos in the Brain
SARS-CoV-2 appears to travel widely across the cerebral cortex
Headaches, hallucinations, vivid dreams, smell & taste anomalies, strokes and seizures
80% of COVID patients encountered neurological complications
Strange New Symptoms Emerge with Latest New Jersey COVID Variant
More loss of smell and taste, insomnia and pronounced anxiety are new symptoms of latest Covid variant as the virus continues to mutate unrestrained, is neuroinvasive, persists in the body and has multiple effects on the brain:
Neuroinvasion and anosmia are independent phenomena upon infection with SARS-CoV-2 and its variants
SARS2 can invade your brain.
All variants are neuroinvasive.
Neuroinvasion and anosmia are independent phenomena upon infection.
SARS2 can travel retrogradely and anterogradely along axons in neuron-epithelial networks.
Long COVID smell loss linked to changes in the brain
"The findings suggest smell loss, known as anosmia, caused by long COVID is linked to a change in the brain that stops smells from being processed properly"

Brain imaging before and after COVID-19 in UK Biobank
"These brain imaging result...hallmarks of a degenerative spread of the disease — or of the virus itself — via olfactory pathways...or of neuroinflammatory events due to the infection, or of the loss of sensory input due to anosmia."
I recovered from COVID but my nose didn't. Here's how I cope
"Roughly 5% of people who experience smell loss during COVID-19 will develop long-term anosmia, according to Dr. Bradley J. Goldstein, an ear, nose and throat doctor at Duke University Hospital.
The impact is more drastic than most people realize."
