Long Covid extends for two years... and this is what it does to the brain


A huge study that included one million people in 8 countries concluded that infection with the longer-term version of Covid-19, known as “Long Covid”, extends for two years, and includes a mixture of symptoms that persist even after recovering from the virus, and are concentrated in the brain.


The study, published by the American "CNN" network, said that adults with "long-Covid" are exposed to symptoms such as epileptic seizures, dementia, brain fog and other mental disorders, noting that the risk of developing these symptoms is still high even after two years of recovery.


The children had an increased risk of epilepsy, seizures, etc., which could lead to pain and loss of sensation in the arm or leg, with a small but worrisome possibility of developing a psychotic disorder such as schizophrenia.


These findings are important, but they should not lead to panic, said study co-author Paul Harrison.


We don't talk about things that are 10 or 100 times more common than normal, said Harrison, a professor of psychiatry at Britain's Oxford University. I think the worst odds ratio is 2 or 3%.


It's a very robust and well-conducted study using data from a large sample and across multiple countries, said Rachel Sumner, a senior researcher at Cardiff University who was not involved in the study.


The findings are worrisome and extremely important in our current context of the ongoing spread of COVID-19, she added by email.


In the study, the researchers examined the data of adult and child patients, who were transferred to hospitals after infection with “Covid-19”, which is caused by the Corona virus, and the data source was the Electronic Health Records Network (TriNetX), which has health data from around the world.


The study examined the cases of 1.25 million patients two years after they were diagnosed with "Covid-19", and compared them to a similar number of people suffering from another respiratory infection.


The researchers compared these two groups through 14 psychological disorders, such as epileptic seizures and brain fog, to show that the effect of "Covid-19" is more.


Most of the patients were from the United States, but the study included others from Australia, Britain, Spain, Bulgaria, India, Malaysia and Taiwan.


The study said that the risk of developing disorders such as brain fog, dementia and psychotic disorders remained high over the past two years compared to people who developed other respiratory infections.


The study stated that in adults over the age of 65, the risk of developing dementia increased by 1.2 percent.


Although this is not a tsunami for new cases of dementia, it is difficult to ignore, given the seriousness involved in diagnosing this medical problem, the researchers commented in the study.
