A study has found that COVID-19 has an impact on human cognition. It is not peer-reviewed, and further evaluation is needed.
Many participants have experienced chronic memory loss, confusion, and delirium. Research held down that the damage caused by the SARS-CoV-2 virus can age the brain by ten years or cause a 8.5 point decline in IQ levels. The analysis was observed after recovered patients were subjected to several tests that determined their cognitive skills.
Participants in the study were asked to do nine tasks to assess their cognitive function, and a team of experts analyzed the results. The subjects were not told that the study assessed the COVID-19's effects until after they had finished to avoid any bias. The findings were published online, and the team is to cross-reference results from the behavioral study with detailed imaging to get a deeper understanding of the damage to the brain. Experts have said that severe forms of illness can cause a host of gradual and lifelong damages, from lung fibrosis, severe fatigue, damage to the heart and nervous system, cognitive impairment, mental illness, and musculoskeletal problems.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
