UCSD research finds COVID damages brain cell synapses
"An international team of researchers led by scientists at UC San Diego School of Medicine has shown that the virus which causes COVID-19 can damage brain cell synapses, according to a report published Thursday."
Like a "fire in the brain": COVID can cause brain inflammation
"A new study in the journal Molecular Psychiatry shows for the first time that SARS-2 can trigger the same inflammatory processes seen in patients with Alzheimer's or Parkinson's."

Another study showing that metabolic pathways activated in brain by covid are similar to the ones that happen in Alzheimer & Parkinson diseases. While the drugs to stop this inflammation are being tested, the inflammation is affecting millions of ppl.
Brazilian study reveals the effects of SARS-CoV-2 infection on the central nervous system
"COVID-19 can infect brain cells, especially astrocytes...Research also broke new ground by describing alterations in the structure of the cortex, the most neuron-rich brain region, even in cases of mild COVID-19."
Long COVID Experts: ‘So Incredibly Clear What’s at Stake’
"It is estimated that more than 1/3 of people who have had COVID-19 also have neurological complications that persist or develop 3 months after infection. And 2/3 of people with long COVID still have neurological symptoms after 6 months"
Study explores COVID-19 effects on cognition
"The study also found that the degree of cognitive impairment was not related to the amount of time that had elapsed between COVID-19 infection and the assessment, suggesting that they might be long-lasting."
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."

Study: A Third of COVID Patients Develop Neuropsychiatric Symptoms
According to research published in JAMA Psychiatry, "1/3 of COVID-19 patients have long-term neuropsychiatric symptoms, including psychosis and anxiety. Researchers believe that the symptoms could be the result of how the virus itself damages the brain."
