There are two main types of strokes:

  • 87 percent are ischemic strokes -- strokes caused by blockage of an artery (major blood vessel)
  • 13 percent are hemorrhagic strokes -- strokes caused by bleeding into the brain

Another type of stroke is called a transient ischemic attack, and is considered a ‘mini-stroke’, or warning stroke. The blood flow is usually only blocked for a short period of time (generally 5 minutes or less.) A transient ischemic attack is still a serious event and all strokes should be taken seriously and treated immediately.

If you or someone with you may be having a stroke, call 911 immediately.
