Coronavirus: Increased Risk of Stroke in COVID-19? – Health


According to a message from the German Society for Neurology e.

V.

(DGN) showed in a recent study from Wuhan 40 out of 88 patients with severe COVID-19 courses neurological symptoms.

Five of them reportedly had a stroke alone.

According to experts, the most common symptoms of coronavirus disease (COVID-19) are fever, fatigue and dry cough.

Most people recover without special treatment.

In rare cases, however, the disease takes a severe course.

In addition, researchers have also frequently identified neurological complaints in COVID-19.

And some infected people also had a stroke.

The number of infections with the new coronavirus SARS-CoV2 is still increasing.

Not all people who are infected with the pathogen show symptoms.

Some patients experience only minor complaints, but others experience severe illnesses.

There are also indications that the virus can also trigger other diseases, possibly a stroke.

Coronavirus: a trigger for stroke?

Further investigation is needed to determine whether the cerebrovascular events are a direct consequence of infection or occur more frequently in critically ill COVID-19 sufferers because they usually have more accompanying diseases that promote stroke.

The DGN underlines that COVID-19 absolutely needs neurological expertise.

The evaluation from China, which was published in the journal “JAMA Neurology”, shows that neurological manifestations are quite common in hospitalized COVID-19 patients.

Severe course of the disease with neurological symptoms

Overall, neurological symptoms occurred in 36.4 percent of the 214 patients.

It was also noticeable that neurological symptoms increased in those with severe respiratory tracts.

According to the DGN, this group showed not only increased, but also more severe neurological manifestations: four patients had an ischemic stroke, one patient had a hemorrhagic stroke, 13 patients had documented changes in consciousness and one had a seizure.

The rate in this subgroup was as high as 45.5 percent (40 out of 88 patients with severe disease had neurological symptoms).

The authors explain the accompanying neurological symptoms by the fact that SARS-CoV-2, like the already known coronaviruses SARS and MERS, can also penetrate the central nervous system (CNS) or the brain, especially the brain stem, such as one at the end of February Publication in the “Journal of Medical Virology” suggested.

According to the DGFN, laboratory parameters of the severely affected COVID-19 patients from Wuhan were evaluated in the present study.

It was striking that those with neurological symptoms had a lower number of lymphocytes, which indicates a reduced immune system.

They also had lower platelet counts and higher blood urea nitrogen (BUN) levels.

In addition, the group of patients with severe respiratory courses also had higher D-dimer levels overall.

This would also explain the extremely high frequency of loss of smell and taste in COVID-19 diseases, which is found in a recent European study to be 85.6 and 88 percent.

The neural route of infection has been demonstrated in animal experiments, it runs from the nasal mucosa via so-called free nerve endings to the brain.
