The cytokine storm is believed to beВ one of the common causes of mortality in the the Covid-19 pandemic, inflicting damage on the heart, liver and kidneys.ДЄbnormal blood clotting, causing heart attack and stroke, has also been highlighted as a significant cause of death in Covid-19 patients. Known as a 'cytokine storm', the deadly complication sees immune molecules start to attack healthy tissue as well. Slight inflammation can happen when the body fights off any viral infection, including Covid-19.Д«ut in some people - particularly the elderly and those with underlying health conditions - their immune systems go haywire while trying to clear Covid-19 in the body. Professor Banks and his team's research focus had been on the blood-brain barrier and its role in Alzheimer's disease, obesity, diabetes, and HIV.Д«ut they focused all of their efforts on studying the coronavirus spike protein in April. The study, published in Nature Neuroscience, may explain why so many patients even with mild illness report feeling fatigued months after clearing the infection. Many of the effects that the Covid virus has could be accentuated or perpetuated or even caused by virus getting in the brain and those effects could last for a very long time.' 'You do not want to mess with this virus. 'We know that when you have the COVID infection you have trouble breathing and thatвЂ™s because thereвЂ™s infection in your lung, but an additional explanation is that the virus enters the respiratory centers of the brain and causes problems there as well. He added: 'The S1 protein likely causes the brain to release cytokines and inflammatory products. Lead researcher William Banks, professor in medicine at the university, said the similarities between HIV and Covid on the brain 'was like dГ©jГ vu'. Thirteen came from France, eight from the UK, five from the US, four from Brazil, four from Argentina, two from India, one from Peru and one from Saudi Arabia.ДЄll had MRI scans after developing symptoms of some form, ranging from a standard fever to problems moving their extremities and impaired cognitive function.Д®ight of the children had no respiratory symptoms such as shortness of breath or a cough, as is typically associated with Covid-19.ДЇour children in the study died after contracting another infection, such as TB and MRSA, after Covid-19 had made them more susceptible.ДЄnd two of the youngsters in the study were left paralysed after the virus reached their spinal cords and caused inflammation. The cases were found after a global call for unusual Covid cases in children was put out by the American Society of Pediatric Neuroradiology.

SARS-CoV-2 has previously been found to cause neurological issues in adult patients, with delirium and strokes among the reported problems.Д«ut there has been very little scientific research into the neurological implications of Covid-19 in children.ДЄ total of 38 children who tested positive for the infection were assessed in the specialist study who had been admitted to hospital across eight countries. Researchers at the University of Manchester looked at neurological symptoms in 38 unusual cases of Covid-19 in under-18s. This wouldn't be a unique phenomenon, as many HIV patients suffer similar cognitive issues due to a protein let off by that virus.Д¬oronavirus infection can cause paralysis in children in very rare cases, a study reveals.

They warned the neurological damage 'could last for a very long time'. However, the Washington researchers believe the spike proteins are also seeping into the brain in some patients and causing inflammation. When a person becomes infected with Covid-19, their immune system targets and attacks the spike proteins, which can cause inflammation because sometimes healthy tissue gets damaged in the process.Д¬ovid-19 normally targets the lungs and respiratory tract, which is why the most common symptoms are coughs and shortness of breath and why many critically ill patients need mechanical ventilation.

They believe the same process may happen in people, which could explain some of the coronavirus' more unusual symptoms, such as headaches, brain fog and even seizures. University of Washington researchers found the virus' spike protein, which it uses to latch onto human cells, can cross the blood-brain barrier in mice, taking the virus with it. Covid-19 may be able to infect the brain because it carries a protein capable of getting through the barrier at the top of the spinal cord, a study suggests.
