Recent study says SARS-CoV2 or COVID-19 could cause
a brain related symptoms like headaches and dizziness apart from being a
respiratory disease because it can also invade the brain and disrupted the
barrier of the brain using its what is so-called spike protein. The coronavirus
uses spike protein to enter cells as the news said as well as the brain.
“While Covid-19 is typically associated with
respiratory symptoms, a significant number of patients also present with neurological complications,
ranging from headaches and dizziness to fatal microclots in the brain.
According to a new study in the journal Neurobiology of
Disease, these effects arise due to the ability of spike
proteins on the SARS-CoV-2 virus to disrupt the blood-brain barrier.” (IFL

“Closer analysis revealed that the presence
of SARS-CoV-2 spike proteins triggered an
inflammatory immune response in brain tissue, much like it does in the lungs,
therefore illuminating the pathway by which the virus produces neurological
symptoms. Further tests using microfluidics that are designed to mimic human
brain capillaries showed that these too became more permeable in the presence
of SARS-CoV-2 spike proteins.”(IFL Science)
“"Our findings support the implication that
SARS-CoV-2, or its shed spike proteins circulating in the blood stream, could
cause destabilization of the blood-brain barrier in key brain regions,"
explained principal investigator Servio Ramirez, a professor of Pathology
and Laboratory Medicine at the Lewis Katz School of Medicine at Temple
University, in a statement. "Altered
function of this barrier, which normally keeps harmful agents out of the brain,
greatly increases the possibility of neuroinvasion by this pathogen, offering
an explanation for the neurological manifestations experienced by Covid-19
patients."” (IFL Science)
