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.

Famous quotes containing the word stroke:
“Now his wars on God begin;
At stroke of midnight God shall win.”
—William Butler Yeats (18651939)
“When any man expresses doubt to me as to the use that I or any other woman might make of the ballot if we had it, my answer is, What is that to you? If you have for years defrauded me of my rightful inheritance, and then, as a stroke of policy, of from late conviction, concluded to restore to me my own domain, must I ask you whether I may make of it a garden of flowers, or a field of wheat, or a pasture for kine?”
—Matilda Joslyn Gage (18261898)
“All I have to do
is hear his name
and every hair on my body
just bristles with desire.
When I see
the moon of his face,
this frame of mine
oozes sweat like a moonstone.
When that man
as dear to me as breath
steps close enough to me
to stroke my neck,
the thought of jealousy
is shattered in my heart
thats hard as diamond
—Amaru (c. seventh century A.D.)
