Statistics tell us that stroke is the second leading cause of death worldwide, and is responsible for about 9 percent of the world’s deaths each year. In the United States, stroke affects more than 700,000 people a year (about one person every 45 seconds), about 500,000 of which are first-time strokes, while the remaining 200,000 are recurrent attacks. Stroke kills someone in the United States every 3.3 minutes.
Stroke is also the leading cause of disability among American adults. More than 4 million Americans have survived a stroke and are living with its effects. About 14 percent of people who have a stroke or TIA will have another one within a year, and 25 percent will another episode within five years.
