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 a 2005 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 tend to 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 major risk factors for stroke. About half of Americans(49%) have at least one of these three risk factors.7Several other medical conditions and unhealthy lifestyle choices can increase your risk for stroke.
Although you can’t control all of your risk factors for stroke, you can take steps to prevent stroke and its complications.
