- Every year, about 800,000 Americans experience a stroke; more than 600,000 of these are first-time victims.
- People who get emergency medical treatment within three hours of their first stroke symptoms tend to have less disability three months later than those who delayed care.
- Ischemic stroke, an obstruction within a blood vessel supplying blood to the brain, accounts for about 87 percent of all cases.
