What is a TIA

A TIA (transient ischemic attack) is a warning sign of stroke sometimes called a “mini-stroke.” It occurs when a blood clot blocks an artery for a short period of time. Symptoms of TIA are the same as stroke and can last minutes to hours. One in 6 people who have a TIA will have a stroke. The greatest risk is within the first week after a TIA. Therefore urgent evaluation within 24-48 hours after a TIA is important, and can be done quickly at a stroke center.

TIA Evaluation includes:
  • Brain imaging with CT or MRI
  • Imaging of the blood vessels that supply blood and oxygen to the brain
  • Heart studies including heart rhythm monitor, echocardiogram, and EKG
  • Blood studies
Warning Signs of TIA
  • Sudden weakness or numbness especially on one side of the body
  • Sudden confusion or trouble speaking or understanding
  • Sudden trouble seeing in one or both eyes
  • Sudden trouble walking, dizziness, or loss of balance and coordination
  • Sudden severe headache with no known cause

If you have one or more of these symptoms even if they last only a few moments, don’t wait call 9-1-1.

If you or someone you know had a TIA or stroke be prepared:

  • Know the Primary stroke centers in your area
  • Keep information about medical history in a convenient place
  • Make a list of current medications including dose, frequency and pharmacy
  • Note what time the symptom first occurred
  • Be certain all family members know to contact a ambulance by calling 9-1-1
