Symptoms of Stroke
Stroke is an emergency. Every minute counts. If someone has symptoms of a stroke, call 911 right away. The longer a stroke goes untreated, the greater the damage and potential disability. Even for symptoms that go away quickly or don't cause pain, it's important to get to an emergency room as soon as possible. The success of most treatments depends on how soon a person is seen by a doctor in a hospital emergency room after symptoms begin.
The most common signs and symptoms include:
