Learning About How to Prevent a Stroke

What is a stroke?

A stroke is damage to the brain that occurs when a blood vessel in the brain bursts or is blocked by a blood clot. Without blood and the oxygen it carries, part of the brain starts to die. The part of the body controlled by the damaged area of the brain can't work properly.

Brain damage can start within minutes of a stroke. But quick treatment can help limit the damage and increase the chance of a full recovery.

What puts you at risk for stroke?

A risk factor is anything that makes you more likely to have a particular health problem.

Risk factors for stroke that you can manage or change include:

  • Health problems like atrial fibrillation, diabetes, high blood pressure, high cholesterol, hardening of the arteries (atherosclerosis), and sickle cell disease.
  • Smoking.
  • Drinking more than 2 alcoholic drinks a day for men and 1 drink a day for women.
  • Being overweight.
  • Not eating healthy foods.
