Studies suggest that coronovirus may cause cognitive decline in some patients


Patients who recover from coronavirus may suffer from an infection of cognitive issues, especially those who develop a severe case of the disease, a new study suggests. The study, which is not yet peer reviewed, analyzed data from 84,285 Great British Intelligence Test participants who completed a questionnaire about suspected and biologically confirmed COVID-19 infection.

The study stated that the trial is part of an ongoing collaborative project with BBC2 Horizon and has not been advertised as a coronovirus-related questionnaire.

Of the test participants, 60 were placed on ventilators, 147 others were hospitalized but did not need ventilators, 176 received medical attention at home for respiratory difficulties, 3,466 had respiratory problems. , But did not receive medical help and 9,201 were ill. Respiratory symptoms. The team stated that 361 self-reports contained a positive biological test.

Dr. of Imperial College London. The research team led by Adam Hampshire found that those who had age, gender, education level, income, racial-ethnic group and demonstrated significant cognitive deficits while accounting for pre-existing medical disorders.

For participants who were reported to be hospitalized and placed on ventilators, researchers found a 10-year decline in cognitive performance. The researchers said the findings echoed previous studies that included patients with respiratory illnesses, but were surprising to patients who remained at home.

Will the enemies have to face?

“[Cognitive deficits] Was of sufficient effect size for those who were hospitalized, but in mild and biologically confirmed cases who reported difficulty breathing, ”the researchers wrote in a post published on Medrix is. “Granular analysis of improved performance supports the hypothesis that COVID-19 has a multi-system effect on human cognition.”

However, experts not included in the study told Reuters that the findings should not be viewed definitively, as the test did not measure for cognitive function pre-infection, and did not provide long-term follow-up.

Derek Hill, a professor of medical imaging science at University College London, told Reuters, “Overall (this) is an intriguing but inconclusive piece of COVID’s impact on the brain”. “As researchers have tried to better understand the long-term effects of COVID, it will be important to examine the extent to which cognition is affected in the weeks and months following infection, and the result of permanent damage to brain function in some people.” Happens in. ”

The team said their findings should promote more research into cognitive deficits in coronovirus survivors.
