Every 40 seconds, someone in the U.S. has a stroke. It could happen on your street, in your workplace, at a store where you shop — anywhere. Your readiness to spot the stroke warning signs and call 911 could save a life or make the difference between a full recovery and long- term disability. That’s why it’s so important to learn the stroke warning signs and urge everyone you know to do the same.

The faster stroke is treated, the more likely the patient is to recover. In fact, stroke patients who are treated with the clot-busting drug IV r-tPA Alteplase within 90 minutes of their first symptoms were almost three times more likely to recover with little or no disability.

In some cases, a procedure to remove the clot causing the stroke is also recommended. Nintey-one percent of stroke patients who were treated with a stent retriever within 150 minutes of first symptoms recovered with little or no disability.

The thing to remember is that stroke is largely treatable. It’s a matter of getting the right treatment, right away.
