Stroke Statistics by Race and Ethnicity

Early Action Is Important for Stroke
Know the warning signs and symptoms of stroke so that you can act fast if you or someone you know might be having a stroke. The chances of survival are greater when emergency treatment begins quickly.
- In one survey, most respondents—93%—recognized sudden numbness on one side as a symptom of stroke. Only 38% were aware of all major symptoms and knew to call 9-1-1 when someone was having a stroke.5
- Patients who arrive at the emergency room within 3 hours of their first symptoms often have less disability 3 months after a stroke than those who received delayed care.6
Americans at Risk for Stroke
High blood pressure, high cholesterol, and smoking are leading causes of stroke. Two thirds of Americans have at least one of these conditions or habits.7
