Covid-19 neurological symptoms emerge in most hospitalized patients, study says

Thursday, 08 Oct, 2020

The most common neurologic symptoms were muscle aches and headaches, which were experienced by about 45% and 38% of patients, respectively.

To arrive at the study findings, which appeared in the Annals of Clinical and Translational Neurology, the researchers examined neurologic manifestations in more than 500 patients who were admitted to a hospital network in Chicago, Illinois, due to COVID-19.

"While it is not unexpected that the sickest patients would have the most neurological complications, it is surprising that these manifestations occur more commonly in younger individuals and is independent of the severity of respiratory involvement", Nath told MedPage Today.

Usually, patients had mild symptoms: attention problems, short-term memory, and altered concentration abilities. Studies out of Europe and Asia have also shown high rates of neurologic symptoms.

About a third of patients hospitalized by the disease, caused by the novel coronavirus, experience encephalopathy, a broad term describing altered brain function or structure, the study found. Encephalopathy was also associated with an increased risk of additional complications and even death. On the other hand, 89% of patients without any mental issues were able to manage such activities independently.

However, there is no clear indication as to what causes encephalopathy, as there is a lack of testing amidst the pandemic.

The authors of the study stated that there is very little evidence that the virus directly attacks brain cells.

According to TIME, the symptoms don't just include damage to the nervous system.

Covid-19 patients who experience even the mildest illness risk suffering symptoms for months, said researchers in a new study.

Those indications included muscle torment (44.8% of each one of those assessed), cerebral pains (37.7%), encephalopathy (31.8%), wooziness (29.7%) and problems of taste (15.9%) and smell (11.4%).

The discovering brings genuine public worries up considering President Donald Trump's ongoing three-night remain at Walter Reed Medical Center, and for a bigger scope they additionally feature the psychological harm the Covid has delivered on countless Americans.

What Are The Mild Symptoms?

His group will be studying that in the future, along with possible immunological factors. For example, dexamethasone, a steroid now used to treat some hospitalized coronavirus patients, can produce side effects such mood changes, insomnia and dizziness. In total, 419 of the 509 patients had neurologic manifestations at any time during the disease course.

Fewer than 6% of patients in the study were evaluated by neurologists or neurosurgeons and more research is needed to determine whether similar findings would emerge within other hospital systems.

"We are now looking to characterize the long-term neurologic effects of COVID-19 and the cognitive outcomes in patients with COVID-19-associated encephalopathy", Koralnik said in a hospital news release. People who all of a sudden can not smell, without explanation, "should consider that as a sign of early Covid-19".
