If you are hospitalized with severe COVID-19, you are more likely to experience Long COVID symptoms such as difficulty breathing, fatigue, and memory loss. [사진=게티이미지뱅크]Research has shown that there are no signs that long-term COVID-19 causes brain damage. Additionally, research has shown that if you are hospitalized with severe COVID-19, you are more likely to experience Long COVID symptoms such as difficulty breathing, fatigue, and memory loss. On the 27th, the health and medical portal WebMD published a bundle of papers by Swedish researchers published in the Journal of Infectious Diseases and papers by Norwegian researchers published in BMC Infectious Diseases. local time) as reported.
Long Covid refers to various symptoms lasting from three weeks to several months after being infected with COVID-19. Scientists around the world are working to understand the wide-ranging condition of Long Covid, from its causes and risks to potential treatments.
The first study used cerebrospinal fluid and blood extracts from 31 Swedish adults to examine changes in the immune system and changes in nerve cells that may affect signaling to the brain. Twenty-five of the participants showed neurocognitive symptoms caused by long Covid, including memory loss and attention problems. Six participants fully recovered from COVID-19, and 17 had never had COVID-19.
People infected with COVID-19 were confirmed between March 2020 and May 2021. Their body fluid samples were collected at least three months after the first symptoms appeared.
Studies have shown that Long Covid is not related to the SARS-CoV-2 virus that invades the brain or causes active brain damage. Researchers at the University of Gothenburg in Sweden said, “There was no significant difference between the two groups when analyzing blood and cerebrospinal fluid for indicators of immune activation or brain damage.” “Therefore, the results of this study suggest that the post-coronavirus state is related to persistent infection, immune activation, or brain damage.” “It suggests that this is not the result,” he said.
In a second study, Norwegian researchers compared the likelihood of developing 17 different Long Covid symptoms. Between February 2020 and February 2021, 53,846 people tested positive for COVID-19 and more than 485,000 people who were not infected were targeted. Most of them did not receive the COVID-19 vaccine during that period.
Studies show that people infected with COVID-19 are more than twice as likely to experience shortness of breath or fatigue. They were also more likely to experience memory loss or headaches compared to people who had never been infected with COVID-19. The researchers only examined symptoms that occurred at least 3 months after diagnosis of COVID-19.
They found that being hospitalized increased the risk of experiencing long Covid symptoms such as difficulty breathing, fatigue and memory loss. The researchers noted a limitation that in Norway, not all symptoms reported during visits to general practice clinics are often recorded, which may have affected the results.
