In recent months, doctors have tried to understand the link between Covid-19 and neurological symptoms and exactly how and why it causes some patients to experience delirium, brain inflammation, stroke and nerve damage. Finally, a scientific study has confirmed that the highly infectious virus can cause neurological damage and claims to understand how he does it.

Covid-19 patients frightening experience neurological symptoms

Theto study, Led by University College London (UCL) researchers and published Tuesday in the brain newspaper covered a sample of 43 confirmed or suspected Covid-19 patients, aged 16-85, at the National Neurology and Neurosurgery Hospital , UCLH. Of these, 10 experienced delirium, 12 had brain inflammation, 8 strokes suffered and 8, nerve damage. According to researchers, these neurological complications were their first and most noticeable symptom of the virus.

They explain the case of a woman who had apparently recovered from the virus into the home from the hospital and sent. "She was disoriented and displays a ritualistic behavior such as putting his coat on and off repeatedly. She reported visual hallucinations, see lions and monkeys in his house, "the researchers wrote. Some fatal neurological symptoms with a particular patient died of encephalitis that destroy the brain.

During a five-week period, they also noted nine cases of a very rare and potentially fatal inflammatory condition called acute disseminated encephalomyelitis (ADEM) -prevalent in children. They noted that in London, normally they only see the number of cases in a period of 5 months "indicating that Covid-19 is associated with an increased incidence of ADEM. »

"We have identified a higher than expected number of people with neurological disorders such as inflammation of the brain, which are not always correlate with the severity of respiratory symptoms," Dr. Michael Zandi (UCL Institute of Neurology, Queen Square and University College London Hospitals NHS Foundation Trust) said in aaccompaniementin the study.

"We must be vigilant and look out for these complications in people who have had Covid-19. That we will see a large-scale epidemic of brain damage associated with the pandemic may be similar to the epidemic of lethargic encephalitis in the 1920s and 1930s after the pandemic flu in 1918-remains to be seen ".

Neurological complications are an immune response to the virus

Researchers say they have pinpointed the relationship between the virus and the neurological symptoms. Instead of being due to the virus attacks the brain, they seem to be an immune response to it.

"Given that the disease has only been around for a few months, we yet know what long-term damage Covid-19 can cause," said UCL researcher Ross Paterson. "Physicians should be aware of possible neurological effects such as early diagnosis can improve patient outcomes. »

"Physicians should be aware of possible neurological effects such as early diagnosis can improve patient outcomes," Dr. Paterson continued. "People are recovering virus should seek health advice if they experience neurological symptoms," he added.
