Yet, while 35 percent of adults in the U.S. have had symptoms suggestive of a TIA, only 3 percent of them called 911 for help, according to a recent online survey of more than 2,000 people by the American Heart Association and American Stroke Association. That’s a mistake, experts say. If you have symptoms of a stroke or TIA, “don't wait it out,” advises Dr. Dion F. Graybeal, medical director of stroke at the Baylor University Medical Center in Dallas. “Take these symptoms seriously and call 911.” If it’s a real stroke, every minute counts in terms of getting treatment and reducing the risk of permanent disability. And if it’s a TIA, “it’s an opportunity to intervene and hopefully stop a process or condition that could cause a stroke with disability in the future,” Graybeal says.
It’s better to be safe than sorry because if you have stroke-like symptoms, it’s difficult to tell immediately if you’re having a TIA or a full-blown stroke, says Dr. Nieca Goldberg, a cardiologist and medical director of the Joan H. Tisch Center for Women’s Health at the NYU Langone Medical Center in New York City. So it’s important to get to the hospital as soon as possible, There, you will most likely have a CT scan, a CT angiogram, an MRI or an MR angiogram of your brain and the blood vessels in your head to look for a blood clot and evidence of damage to the brain. If damage isn’t apparent and the symptoms have resolved, the episode will be deemed a TIA. But if there is evidence of damage to areas of the brain, the event will be diagnosed as a stroke, even if the symptoms have gone away, Goldstein says.
