Early Care Is Important
Recognizing the symptoms of a stroke and seeking prompt medical care can greatly improve your chances of recovery. When someone is having a stroke, they need prompt emergency medical care. During a stroke, blood supply to the brain is cut off or disrupted, causing part of the brain to go without the oxygen-rich blood it needs. The longer the brain goes without blood, the greater the chance a disability will occur.
The National Institute of Neurological Disorders and Stroke conducted a five-year study on the use of tPA. The study found that patients who received tPA within three hours of the first stroke symptoms were at least 30 percent more likely to recover with little or no disability after three months.
When a person is having a stroke, doctors must first determine whether the stroke is caused by a clot (ischemic stroke) or by a ruptured blood vessel (hemorrhagic) before tPA can be used. This is because tPA can only be used for ischemic strokes, which account for about 85 percent of all strokes.
