Stroke is the third leading cause of death in the United States, with approximately 700,000 new or recurrent cases each year. The prevalence within the United States has been estimated at 4.7 million, with a cost of $51.2 billion annually. Stroke refers to the neurologic dysfunction resulting from a derangement of the blood supply to the brain or spinal cord. The neurologic symptoms of a stroke are often of sudden onset and may be temporary or permanent. Strokes may be ischemic, resulting from impaired blood flow, or hemorrhagic. Cerebral ischemia is a potentially reversible alteration of brain function that results from inadequate delivery of critical blood-borne substrates such as oxygen and glucose. Cerebral infarction occurs if ischemia is severe enough to kill cells. In this circumstance, there is a high likelihood of permanent dysfunction. The brain is particularly sensitive to severe ischemia, with irreversible cell death resulting in 2 to 3 minutes in some species and in...
