  • According to a new study by British scientists, due to a pandemic, a rare and sometimes fatal inflammatory neurological disease is prevalent.
  • The researchers found that adult acute diffuse encephalomyelitis (ADEM) peaked, which is a rare disease common in children and can be caused by a viral infection.
  • The researchers found evidence that brain inflammation is most likely caused by an immune response to the disease.

Researchers are still discovering different ways COVID-19 can affect the human body.

Now, a new study conducted in the UK has found that COVID-19 neurological complications may include irritability, brain inflammation, stroke and nerve damage.

According to a new study by British scientists, the prevalence of a rare, sometimes fatal inflammatory neurological disease seems to be increasing due to the pandemic.

The research was published this week in the journal Brain and was led by researchers at University College London and University College Hospital.

In particular, during the study period, the researchers found that acute diffuse encephalomyelitis (ADEM) in adults showed a peak growth, which is a rare disease that is usually seen in children and can be triggered by a viral infection. Researchers usually see an adult patient with this condition every month.

However, during the study period, they averaged 1 adult with ADEM per week.

In this study, the researchers reviewed the clinical, radiological, laboratory, and neuropathological findings of 43 COVID-19 patients aged 16 to 85 years who were diagnosed or suspected. The patient was treated at the National Neurology and Neurosurgery Hospital in London. There are 24 men and 19 women in total. Twenty-nine of these patients were defined as confirmed COVID-19, possibly 8 or 6. The severity of COVID-19 symptoms varies from mild to severe.

The researchers identified 10 cases of transient brain dysfunction caused by transient encephalopathy or temporary delusion. There were also 12 cases of brain inflammation, 8 strokes and 8 nerve injuries.

The researchers found evidence that brain inflammation is most likely caused by an immune response to the disease. The researchers say this suggests that some of the neurological complications of COVID-19 may come from the immune response, not the virus itself.

The researchers say this new study confirms the previously reported finding that the number of stroke patients is higher than expected-the stroke is caused by COVID-19 patients whose blood is “excessively thick”.

They still say that because the disease only exists for a few months, the long-term damage to COVID-19 is unclear.

In addition, experts are not sure why the virus increases the risk of these nervous system challenges.

“Possibilities include the direct effects of viruses, the body’s own immune or inflammatory response, the effects of hypoxia (low oxygen levels in the body), changes in blood vessels, changes in blood clotting (viscosity), and the effects of serious diseases (including Extended ICU stay time in some patients) or a combination of these factors,” said Dr. Rachel Brown, a clinical researcher at University College London and one of the first authors of the paper.

“We have seen the neurological effects of COVID-19 on adult patients of all ages, genders, and races, as well as patients with or without health status and mild and severe COVID-19 infection. As a retrospective cohort study, we are currently unable to Tell why these specific patients are affected, but this should be the focus of future research.”

Brown added that although researchers cannot accurately estimate the number of people affected, neurological complications of COVID-19 may be rare.

She said: “We may be reporting a more severe situation in this regard.” For patients with neurological complications, the impact may change lives and should not be understated. As always, we need to seriously consider COVID-19 and continue to follow public health recommendations to limit the spread of the virus and the number of people affected. “

Dr. Serena Spudich, a professor of neurology at the Yale School of Medicine, called the study “a very valuable collection of descriptions by a group of world-class neurologists. They all work together to try to draw a consistent conclusion from a different point of view. It represents a group of patients. The best and most thoughtful series of clinical cases.”

Dr. Guilherme Dabus, an interventional neuroradiologist at the Miami Heart and Vascular Institute and the Baptist Neuroscience Institute, still says that this research shows that we are still wondering why certain patients develop neurological syndrome and why there are so many For different reasons, the types of neurological manifestations of those people are not well understood.

He pointed out that this emphasizes the need for the medical community to be aware of possible neurological syndromes that may affect COVID-19 patients, so they should pay attention to signs and symptoms.

He said: “Some neurological manifestations such as stroke are sensitive to time, and rapid suspicion and diagnosis may be the difference between life and death.”

Interventional neuroradiologist, director of the Stroke and Aneurysm Center of the St. John’s Health Center in Providence, Santa Monica, California, and neuroradiologist Dr. George Teitelbaum added that the study showed that COVID-19 ultimately proved to be a very Virulent virus with multiple presentations.

He said: “It turns out that it is a more complicated virus than we thought.”

He added that one of the lessons of this study is to remind people that they must follow basic precautionary guidelines, such as using masks, hand sanitizers, and staying away from society.

He said: “These are very effective in reducing the spread.” “This is not a political issue; this is a public health issue. For some people, this is a matter of life and death, especially if they are older Large and has potential conditions. This is not aerospace technology.”
