Covid s harmful effects on the brain reverberate years later
Covid-19 survivors remain at higher risk of psychotic disorders, dementia and similar conditions for at least two years, according to a large study that highlights the mounting burden of chronic illness left in the pandemic’s wake
Omicron better at invading young noses than other variants; smell loss may predict memory issues | Inquirer News
Brain damage after even mild Covid in kids: Omicron is much better at invading children's noses, predicts memory issues. "Severity of smell dysfunction after infection may be a better predictor of long-term cognitive impairment than severity of COVID-19"
Common viruses may be triggering the onset of Alzheimer’s disease
"... researchers also noted the #long_term #neurological effects that some COVID patients have experienced from the #SARSCoV2 virus, particularly among the elderly, and that both #VZV and #HSV_1 can be reactivated after a #COVID #infection."
SARS-CoV-2 is associated with changes in brain structure in UK Biobank
UK researchers scanned the brains of 400 people before and after mild covid, compared them with controls and found:
- greater reduction in grey matter thickness
- greater reduction in global brain size
- greater cognitive decline
- greater change to primary olfactory cortex
COVID-19 Linked to Significant Brain Changes, Shrinkage
Covid linked to significant brain shrinkage: "Even a mild COVID-19 infection can change the brain. People infected had a greater reduction in brain volume and performed worse on cognitive tests than those who did not contract COVID-19."
You're not imagining 'COVID brain' — here's the latest evidence
COVID cognitive decline more widespread than thought say researchers at Australia's first long-COVID clinic Some sort of cognitive decline was recorded in almost all of the participants, regardless of the severity of the initial infection.
How Effects on the Brain Can Produce Long COVID - Neuroscience News
"Even with mild cases, COVID-19 can cause confusion, delirium, sleepiness, poor cognitive function, intense headaches, and uncomfortable skin sensations. In more severe cases, patients have suffered complications as serious as strokes."
COVID-19 brain fog | CityNews Toronto
"Bluntly and rather disconcertingly, Pirzada says if someone is dealing with significant brain fog, there isn’t much that can be done...
'We can refer you to a specialist that will see you in the long term, but they won’t know what to do either,'"
Physical, psychological and cognitive profile of post-COVID condition in healthcare workers, Quebec, Canada
"Persistent cognitive and other professionally-disabling sequelae of COVID-19 in essential workers could have critical implications for quality healthcare delivery during and after the pandemic."
Memory loss and 'brain fog' may be side effects of COVID-19, new study shows
Study: Long-term COVID-19 side effects could include memory loss and other cognitive dysfunctions.
Most common cognitive deficits: memory encoding and memory recall, which showed up in 24% and 23% of the participants, respectively.
