Stroke Home > Risk Factors for a Mini-Stroke and Possible Signs

Risk Factors

Risk factors are conditions or behaviors that increase your chances of getting a certain disease. The more risk factors you have, the greater your chances of having a mini-stroke. That's because risk factors tend to "gang up" and worsen each other's effects. Also, the higher your level of each risk factor, the greater your risk of having a mini-stroke. Some mini-stroke risk factors can be treated or controlled and some cannot.
Mini-stroke risk factors that you cannot change include:
  • Age (risk of a mini-stroke tends to increase with age)
  • Being male
  • Being African American
  • Having a family history of mini-stroke
  • Having had a mini-stroke or heart attack.
Some of the most important treatable or controllable risk factors for mini-stroke are:

Mini-Stroke Symptoms

For a person having a mini-stroke, the symptoms will vary depending on which part of the brain is affected. Examples of specific mini-stroke symptoms can include:
  • Sudden numbness or weakness of face, arm, hand, or leg, especially on one side of the body
  • Sudden confusion
  • Trouble speaking or understanding speech
  • Sudden trouble seeing in one or both eyes (such as double vision, blurred vision, or blindness)
  • Sudden trouble walking
  • Sudden dizziness or lightheadedness
  • Sudden loss of balance or coordination
  • Sudden severe headache with no known cause
  • Vomiting
  • Loss of consciousness
  • Spinning sensation (vertigo)
  • Sudden collapse
  • Seizures (in a small number of cases).
If you suspect that you or someone you know is experiencing possible symptoms of a mini-stroke, do not wait for the symptoms to worsen or improve. Call 911 immediately. It is impossible for you to know whether these are mini-stroke symptoms or something more serious (e.g., stroke symptoms).
