New way to protect brain from stroke damage
...brain. In ischemic stroke, the most common form, a blood
vessel that carries oxygen and nutrients to the brain becomes blocked by a clot. As a result, part of the brain fails to get the oxygen it needs, a condition that damages nerve cells. The effects of a stroke, which can include paralysis and problems ...
