Known as large vessel occlusions, or LVOs, they can obliterate large parts of the brain responsible for movement, speech and decision-making in one blow because they are in the main blood-supplying arteries.
Many researchers suspect strokes in covid-19 patients may be a direct consequence of blood problems that are producing clots all over some people’s bodies.
Clots that form on vessel walls fly upward. One that started in the calves might migrate to the lungs, causing a blockage called a pulmonary embolism that arrests breathing — a known cause of death in covid-19 patients. Clots in or near the heart might lead to a heart attack, another common cause of death. Anything above that would probably go to the brain, leading to a stroke."
