Neurological symptoms are commonly reported in people with post-COVID conditions – symptoms that last for four or more weeks after the initial infection.
But a new study by Yale University researchers found that even people with mild infections can sustain neurological damage.
In an interview with NBC Connecticut, Dr. Akiko Iwazaki, who conducted the study, explained that the researchers deliberately gave mice a mild respiratory infection caused by the virus that causes SARS-CoV-2, COVID-19.
In seven days, they examined the impact of the infection on the brain.
“What we found was that even with the mildest infection that could not measure the phenotype of any of these mice, we still found some significant damage to brain cells,” said Ivasaki, an immunologist at Yale University School. Medicine. “This means that even a mild respiratory infection can lead to neurological symptoms; it is based on the damage we see.”
However, the doctor stressed that people with severe illness are at higher risk for cognitive impairment.
Cited by Yale researchers Study It examined Covid patients in the New York City hospital setting and determined that the incidence of cognitive impairment was increased in hospitalized patients compared to those with mild Covit disease.
Persistent cognitive impairment is said to affect approximately one in four COVID survivors. Study About the frequency and different types of symptoms associated with the disease.
As Govt-19 testing increases across Illinois, more and more residents are searching for the latest information on corona virus testing in the Chicago area.
As for newer variants like Omigron, the impact and severity are unknown, the researchers noted.
It is thought that “the vast majority” of survivors of Covit-19 will be affected by post-Covid conditions as a whole, but the cause of the persistent symptoms is not yet known.
“Whether it affects the nervous system or the GI tract or the trachea, the long goit can affect many organ systems,” Iwasaki said. “At present, we do not understand how long Kovit occurs. If we do not understand it, we do not know how to treat these diseases better. So in the end, we want to understand the basic mechanism of the disease. We can come up with a treatment to treat these patients.”
