What is a mini-stroke?

A mini-stroke is when a person has the signs of a stroke, which then completely go away. Most mini-strokes get better within a few minutes, although they can last several hours.

A “mini-stroke,”or transient ischemic attack (TIA), occurs when blood flow is temporarily cut off to the brain, causing stroke-like symptoms. In a healthy person, blood travels to the brain through arteries in the neck called the carotid arteries. If these arteries are blocked by the build-up of a substance called plaque, a transient ischemic attack or stroke can result.

TIA symptoms can include any of the following:

  • numbness or paralysis (usually on one side of the body)
  • difficulty speaking or understanding
  • temporarily dimmed or blurred vision

These symptoms resolve within a few minutes or hours (usually within 24 hours), but they are your body’s warning to contact your doctor right away. More than a third of people who experience a TIA will later have a stroke. A TIA can therefore serve as a warning—and an opportunity to identify carotid artery disease before a more serious medical event takes place.
