A stroke is a sudden interruption of blood flow to a region of the brain, due either to a blockage in, or the bursting of, one of the vessels supplying that region. The interruption of blood flow leads to the injury and death of brain cells, and can thus result in paralysis, cognitive impairment, and other significant disabilities. Today, early interventions are available to reduce the likelihood of such disabilities after a stroke. Know the signs of stroke so that you can seek medical help immediately . . . .
