1. Most strokes are classified as ischemic strokes, meaning they occur when blood is prevented from reaching the brain. Nearly nine in ten strokes are of the ischemic type, while the remaining 13 percent are classified as hemorrhagic strokes.

2. A hemorrhagic stroke occurs when a blood blood vessel inside the brain bursts, resulting in internal bleeding.

3. According to the Centers for Disease Control and Prevention (CDC), strokes afflict roughly 800,000 people every year.

4. Some risk factors for stroke are beyond your control, such as age, sex, and ethnicity.

5. Other risk factors can be mitigated with healthy lifestyle choices, such as reducing alcohol consumption and exercising sufficiently on a regular basis.

6. Some people may experience mini-strokes, known by the medical term transient ischemic attack (TIA). Such strokes may indicate that the affected individual is at greater risk of a more severe stroke in the future.

7. When it comes to treating stroke, time is of the essence. Three hours after a stroke occurs, the risk of long-term brain damage from stroke increases significantly.

8. Signs of stroke include face drooping, dizziness, walking difficulties, or loss of balance or coordination.

9. Other red flags include severe headache, impaired vision, confusion and sudden numbness of the face, arm, or leg.

10. In just one minute, an ischemic stroke can kill nearly two million brain cells.
