For 8 months, the world fought the new Corona, doctors and researchers revealed that the coronavirus mainly attacks the lungs and respiratory system, and it may be transmitted to some other organs such as the liver and kidneys.
A recent study showed that patients are infected with a virus Corona, Often they suffer from neurological symptoms, which can be a warning sign of the impact of the new Corona virus on the brain and its attack on it.
The warning signs are “delirium, severe confusion, headache,” and the mechanisms that cause these brain problems remain largely unknown.
Akiko Iwasaki, an immunologist at Yale University, said that the previous symptoms are clear evidence that the coronavirus in some people invades brain cells and hijacks them to make copies of itself, and it appears that the virus absorbs all nearby oxygen, which leads to starving neighboring cells to death, according to For “Russia Today”.
Brain injury is likely to be rare, but some people may be susceptible to it due to their genetic backgrounds, high viral load, or other reasons.
The study indicated that scientists are still trying to synthesize how the virus entered the brain in the first place, and whether it could be kept away from the brain, and brain tissue was examined that was dissected for three samples, the first from a patient who died of “Covid-19”, and the second for a mouse infected with Covid-19 and the third sample included organelles, groups of cells grown in a laboratory dish to mimic the three-dimensional structure of brain tissue.
Dr. Maria Nagel, professor of neurology and ophthalmology at the University of Colorado School of Medicine, said that the virus can enter nerve cells through the ACE2 receptor, which is a protein on the cell surface that the virus uses to enter the cell and stimulate infection.
Then they used an electron microscope, using bundles of charged particles to illuminate the tissues, to look inside the infected cells, and they were able to see the corona virus particles “budding” inside the cell, which indicates that the virus has hijacked the internal mechanism of nerve cells to build new copies of itself.
Specialist in neurosurgery: Coronavirus causes brain disease
Dr. Mustafa El-Fouly, a professor of neurosurgery, explained that the emerging corona virus causes its complications, inflammation in the peripheral nerves, loss of the sense of smell, clots in the brain, bleeding in the brain, inflammation of the brain membranes, “meningitis”, inflammation of brain cells, and it may cause a virus Corona for the recovered Encephalopathy, meaning irregular behavior, memory disorder, confusion, dementia and Alzheimer’s.
Not all patients suffer from brain damage or encephalitis, and it is not a requirement that all symptoms be present in one patient, according to Al-Fuli in his interview with Al-Watan.
A neuroscientist stated that a Corona patient may suffer from encephalitis and may pass from the virus safely, and there are already recorded cases of patients suffering from brain infections as a result of the Corona virus, “A patient may develop encephalitis during the appearance of Corona symptoms, and a patient may subside, and the symptoms of encephalitis begin to appear. “It affects his movement and memory, causes a high fever, and his neck has limited movement.”
Patients with encephalitis are either in the cells or in the brain wall, and the patients must be inside the hospital, because such an infection means that the patient is in a serious condition and must be treated in the hospital, and the symptoms of the disease can be treated or the cell inflammation itself can be treated according to the doctor’s opinion.
And patients with “Encephalopathy” are in good health and have recovered from Corona or their symptoms began to disappear “complications after the primary disease”, and there are few cases, not many, but complications of the Corona virus have been recorded.
Virologist: Corona does not have a fixed effect on humans
Dr. Sherif Hatta, a professor of viruses and preventive medicine, said in his speech to Al-Watan that the Corona virus does not have a fixed effect on the human body, rather its symptoms differ from person to person according to the response of the immune system, the efficiency of the lungs’ work, genetic factors and disease history, but the virus is mainly concerned with By attacking the lung and respiratory system.
The professor of preventive medicine and viruses confirmed that elderly patients and those suffering from chronic diseases such as pressure, diabetes, heart disease, and those with weak immunity are most vulnerable to complications from the Corona virus, and among the most serious complications is the formation of clots, whether in the lung, brain, or pulmonary artery, which causes the muscle to stop. Heart or strokes.
Hatta explained that Covid 19 causes severe symptoms to patients, and sometimes once the lung is infected and severe symptoms occur in other places, this means that the virus has become present in the blood and affects the rest of the body, which weakens the possibility of the patient’s survival and survival from the disease.
