A investigation –Still considered preliminary — provides information to explain the reasons some people have neurological symptoms after contracting covid-19.

Indicates that el SARS-COV-2 enters a person’s body through the nose, and easily reaches the brain by infiltrating its cells, and this can lead to memory problems or mental confusion that some people have suffered, even long after their infection.

The investigation consists of two studies of the California National Primate Research Center, and of Rotman Research Institute of Toronto. Both of them suggest that this virus directly infects neurons.

Both studies were presented this week during a meeting of the Neuroscience Society, and could shed light on the symptoms of this disease, same as affect at least a third of the 46 million patients that has been in the United States.

“Still we are in the phase where it does not even have a name”NBC quotes Dr. Nir Goldstein, director of the Post-Covid Care and Recovery Center at National Jewish Health in Denver, who was not involved in the investigation.

The virus that causes covid-19 has potential to sneak into the brain despite the body’s natural blood-brain barrier, as can others like HIV. And when it happens, the brain’s immune cells fight off the invader.

But since neurons are vital to the functioning of the body, the immune system does not attack them not even if they are sick, so once the virus is in neurons, it moves freely through brain circuits.

“I think it is a much more dangerous infection. (If the virus can travel through brain circuits), it can reach multiple brain regions that mediate things like cognition, memory, emotion, and mood.“Said John Morrison, who is a professor of neurology at the University of California, Davis, and also directed the research.

On the other hand, the doctor Walter Koroshetz, director of the National Institute of Neurological Disorders and Stroke, says he is not convinced that SARS-CoV-2 can infect neurons, and argues that much more research is needed on this.
