"After Severe COVID, Cognitive Trajectories Go One of Three Ways
— Cognitive impairment persisted for 1 year in some patients age 50 and older"
"Long Covid changes the human brain. We may finally know how
Lost connections between nerve cells in the brain may explain cognitive symptoms such as brain fog and memory lapses."
"How COVID-19 Can Affect Your Child's Brain
Some children develop neurological symptoms from COVID-19, including brain fog, memory issues, headaches, and trouble concentrating. We spoke with pediatric neurologists to learn more..."
"Instead of disease severity, loss of smell seems a more promising avenue for predicting who develops persistent cognitive changes after SARS-CoV-2 infection."
Loss Of Smell Linked To Long Term Covid Cognitive Impairment
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"
UK researchers scanned the brains of 400 people before and after mild covid, compared them with controls and found:
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."
According to a systematic review on the COVID-19 survivors, "Seventy-nine percent of COVID-19 survivors at 1 months and 75% at 3- and 6-month follow-up showed cognitive impairment.."
3 in 4 is a quite high ratio.
