ANNOUNCER: What's tricky with stroke is that sometimes the symptoms may be momentary, but they are a warning that must be acted on promptly.
THOMAS KWIATKOWSKI, MD: Sometimes patients have these symptoms and they last only a few minutes, and that's what we call a TIA or a transient ischemic attack. And that goes away and someone might feel that they are fine after that, but it's very important to keep in mind that that is a warning sign of a stroke. So that if you ever had any of the symptoms of the stroke, even if it goes away quickly, it's very, very important to see a doctor or go to a hospital quickly. Because that is a warning sign that you could have a more severe stroke in the near future.
ANNOUNCER: Ignoring the signs of a stroke and not getting to a hospital immediately could make a serious problem even worse. A problem that might have been taken care of with prompt attention.
ROSE GONZAGA-CAMFIELD, RN: Let's say this happens like 10:00 in the evening, they say, "Let me go to bed. Maybe when I wake up in the morning, I'll be fine." They don't wake up; they don't get up, because when they get up, they don't realize that one side is weak. They get up and they fall on the floor.
THOMAS KWIATKOWSKI, MD: Sometimes when I'm at work, I find out that, at home, the patient had very mild symptoms. By the time they called an ambulance and arrived at the hospital, the symptoms had gotten much worse.
