Know your risk of stroke

Frequently asked questions about stroke
Stroke symptoms can come on suddenly. Call 911 and go to the nearest ER if you experience any of these stroke symptoms:
Balance: sudden onset of dizziness or balance issues
Eyes: double vision or loss of vision
Face: asymmetrical weakness or drooping on one side of face
Arm: one sided arm or leg weakness
Speech: Listen for slurred speech
Time: call 911 immediately
A stroke occurs when there is a disruption in the blood supply to the brain. This disruption can come from a blocked blood vessel in the brain or a blood vessel that ruptures and bleeds into the brain. When you are experiencing a stroke — every second counts. Call 911 and go to the nearest ER.
If you think someone is having a stroke, ask them to repeat a sentence back to you, smile at you, and raise both arms. If they have trouble with any of these tasks, call 911 right away. Stay with the person and note the time they began to have symptoms. This information can help the emergency room care team.
When someone experiences stroke symptoms that go away in a short period of time (typically less than an hour), it may be considered a TIA (transient ischemic attack.) When blood flow to the brain is interrupted for a short period (usually less than five minutes), it may be a sign of a future stroke. TIA is an emergency like stroke. If you experience signs of a stroke or TIA, don't wait to see if the symptoms go away. Call 911 and go to the nearest ER.
The sooner you get to the ER, the more options there may be for treatment. Medications and minimally invasive stroke interventions help remove clots and dissolve blockages to restore blood flow to the brain for ischemic (non-bleeding) strokes. For certain hemorrhagic strokes (bleeding strokes), endovascular procedures are used to repair the blood vessel. Your doctors, nurses, and rehabilitation therapists help you recover after a stroke and help prevent a future stroke.
