Study shows that COVID-19 causes cognitive decline among those without long COVID symptoms
“A new study in eClinicalMedicine has found that healthy volunteers infected with SARS-CoV-2 had measurably worse cognitive function for up to a year after infection when compared to uninfected controls. Significantly, infected controls did not report any symptoms related to these cognitive deficits, indicating that they were unaware of them.”

The net effect is that potentially billions of people worldwide with a his
“But this week 2 new publications have substantially added to our understanding of the extent that Covid can impair cognitive function across the full gamut— from young, healthy individuals with mild infections to older, hospitalized patients with severe Covid.”

Cognitive and psychiatric symptom trajectories 2–3 years after hospital admission for COVID-19: a longitudinal, prospective cohort study in the UK
“Participants had worse cognitive scores than would be expected on the basis of their sociodemographic characteristics across all cognitive domains tested (average score 0·71 SD below the mean [IQR 0·16–1·04]; p<0·0001). Most participants reported at least mild depression (263 [74·5%] of 353), anxiety (189 [53·5%] of 353), fatigue (220 [62·3%] of 353), or subjective cognitive decline (184 [52·1%] of 353), and more than a fifth reported severe depression (79 [22·4%] of 353), fatigue (87 [24·6%] of 353), or subjective cognitive decline (88 [24·9%] of 353). Depression, anxiety, and fatigue were worse at 2–3 years than at 6 months or 12 months, with evidence of both worsening of existing symptoms and emergence of new symptoms. Symptoms at 2–3 years were not predicted by the severity of acute COVID-19 illness, but were strongly predicted by the degree of recovery at 6 months”

“We found persistent subjective and objective cognitive issues even two years after infection, including brain fog, word-finding problems, working memory deficits and reduced processing speed.”

COVID's Inflammation Linked to Long-Term Brain Effects - Neuroscience News
“A significant portion of COVID-19 survivors, even those who had mild cases, may experience cognitive decline and difficulty concentrating for extended periods after the infection.”
