Stroke

Stroke was the second most common cause of death worldwide in 2004, resulting in 5.7 million deaths (~10% of the total). Approximately 9 million people had a stroke in 2008 and 30 million people have previously had a stroke and are still alive. It is ranked after heart disease and before cancer. Geographic disparities in stroke incidence have been observed, including the existence of a "stroke belt" in the southeastern United States, but causes of these disparities have not been explained.
