Ask the experts

What is a "TIA" and how would I know if I was having this type of attack?

Doctor's response

A TIA (transient ischemic attack) is a mini or warning stroke - it would have the same symptoms as a stroke might, which may include weakness on one side of the body or one extremity, difficulty speaking, sudden dizziness, sudden decrease in vision, or other symptoms (see section on stroke warning signs). With a TIA all symptoms return to normal with no residual deficit in less than 24 hours; it may be as brief as a few minutes. If these symptoms occur call your doctor immediately or call 911 and go to the nearest emergency room.
