Stroke Facts
Stroke is the fifth leading cause of death in the United States, killing about 140,000 Americans each year—that’s 1 of every 20 deaths.


A stroke, sometimes called a brain attack, occurs when a clot blocks the blood supply to the brain or when a blood vessel in the brain bursts.
Someone in the United States has a stroke every 40 seconds. Every four minutes, someone dies of stroke.

Every year, about 795,000 people in the United States have a stroke. About 610,000 of these are first or new strokes; 185,000 are recurrent strokes.

Stroke is an important cause of disability. Stroke reduces mobility in more than half of stroke survivors age 65 and over.

Stroke costs the nation $34 billion annually, including the cost of healthcare services, medications, and lost productivity.

You can’t control some stroke risk factors, like heredity, age, gender, and ethnicity. Some medical conditions—including high blood pressure, high cholesterol, heart disease, diabetes, overweight or obesity, and previous stroke or transient ischemic attack (TIA)—can also raise your stroke risk. Avoiding smoking and drinking too much alcohol, eating a balanced diet, and getting exercise are all choices you can make to reduce your risk
