Experts are still learning about the many possible symptoms of the coronavirus. And new research suggests that COVID-19 can also cause neurological symptoms – especially in severe cases.
For the study, published in the journal this week Annals of Clinical and Translational NeurologyThe researchers examined data for 509 COVID-19 patients enrolled in a network of Chicago hospitals. Of these hospitalized patients, 215 had neurological symptoms at the onset of their illness and 319 had these symptoms when they were hospitalized. At the end of their illness, 82% of the hospitalized patients (419 people) had neurological symptoms.
These symptoms included a variety of problems arising from the nervous system. The most common were mild and included muscle pain (45% of patients during their illness), headache (38%), and dizziness or dizziness (present in 30%). Another relatively common complication in this group was encephalopathy, a condition in which brain function changes in such a way that, according to the National Institute for Neurological Disorders and Stroke, confusion, memory problems, and difficulty concentrating can occur. About 32% of hospitalized patients had this symptom. Most patients with neurological symptoms (71
These results come from a relatively small sample of hospitalized COVID-19 patients. Therefore, it is not clear how common these symptoms are in all people with coronavirus infections. However, these results suggest that COVID-19 can cause neurological symptoms – especially in patients with more severe illness and in patients who need to be hospitalized. “This study underscores the high incidence and range of neurological manifestations that occurred in more than four-fifths of COVID-19 patients admitted to our hospital network system,” the study authors conclude.
It’s not entirely clear why viruses – including the new coronavirus – cause neurological problems like headaches, but we know that headaches are very common in viral diseases, SELF previously explained. However, that doesn’t mean that old muscle aches, headaches, or dizziness are a clear sign that you have COVID-19. It’s important to put these symptoms in context with other COVID-19 symptoms someone might experience, such as: B. fever, cough, or shortness of breath. And if there is any confusion, it is worth reaching out to a healthcare provider who can provide recommendations on tests and other measures.
