Because stroke injures the brain, one is not able to perceive one's own problems correctly. To a bystander, the stroke patient may seem unaware or confused. A stroke victim's best chance is if someone around her recognizes the stroke and acts quickly. Bystanders should know the signs and act in time. If you believe someone is having a stroke if they lose the ability to speak, or move an arm or leg on one side, or experience facial paralysis on one side call 911 immediately.
Stroke is a medical emergency.
Immediate treatment may save someone's life and enhance his or her chances for successful rehabilitation and recovery. The window of opportunity to use t-PA to treat stroke patients is three hours, but to be evaluated and receive treatment, patients need to get to the hospital within 60 minutes. There are things you can do to prevent stroke. High blood pressure increases your risk of stroke four to six times. Heart disease, especially a condition known as atrial fibrillation or AF, can double your risk of stroke.
