Observing the progress of the COVID-19 coronavirus has helped to identify new symptoms. Doctors noticed: patients tell doctors about neurological symptoms. Infectious disease continues to spread throughout the planet and new evidence on the course of the disease helps to get more new information about COVID-19. A third of patients report neurological symptoms. In most cases, the disease is accompanied, as in respiratory infection, fever, chest pain, increased fatigue, sore throat, cough, shortness of breath.
But in addition to this, scientists have identified virus-infected cells not only in the respiratory tract but also in the gastrointestinal tract, which manifests itself in the form of nausea and diarrhoea. Cases of heart damage and bleeding disorders have also been reported.
New studies have summarized the main neurological symptoms in patients with COVID-19. In people with Guillain-Barré syndrome, they are most pronounced. Guillain-Barré Syndrome is a neurological disease in which the immune system responds to an infection and as a result erroneously attacks nerve cells, leading to muscle weakness and ultimately paralysis.
Several similar cases have already been recorded in the world. Encephalitis was diagnosed in young patients: inflammation and cerebral oedema, and subsequent stroke. In this case, the symptoms of coronavirus in them were considered mild. Studies in France and China have shown that about 36 per cent of patients have neurological symptoms.
In some, they appear weaker, in others, it is stronger. For example, severe headache or dizziness with COVID-19, these are signs of a clear immune response to the infection. More specific signs are convulsions, loss of smell and taste, muscle pain, stroke, physical weakness, hallucinations.
Such symptoms are most often observed in severe cases, while the level of neurological manifestations can range from 46 to 84 per cent. New symptoms that doctors note in such situations are associated with disorientation, disorders of motor functions. In some cases that were considered severe, these changes persisted after the patients recovered.
