An analysis links COVID-19 to brain microvascular injury and inflammation

The ongoing COVID-19 pandemic is caused by the severe acute respiratory syndrome-2 (SARS-CoV-2), an RNA virus that belongs to the family Coronaviridae. According to research, coronavirus disease 2019 (COVID-19) patients often suffer from neurological disorders like strokes, lost taste or smell, memory loss, confusion, and delirium.
