If one of your loved ones was doubled over with chest pain, having what appeared to be a heart attack, or witnessed someone sustain severe injuries, you would probably call 911 so they could receive medical attention as quickly as possible. What if you observed someone suddenly lose the ability to speak, move parts of his or her body or have trouble seeing? Would you react the same way? The answer is probably yes, if you recognize the symptoms of a stroke.
Knowing what symptoms to look for and reacting quickly may save a stroke victim’s life and may increase their chances for a successful recovery. Every minute counts when someone is having a stroke. Stroke patients who receive treatment in the first hour have the best chance for surviving and preventing disability. Despite the need for early diagnosis and treatment, only 25 percent of ischemic stroke patients reach the ER within an hour of the onset of symptoms.
During a stroke, the blood supply to the brain is interrupted. Brain cells in the immediate area begin to die because they stop receiving the oxygen and nutrients they need to function. This is why immediate medical attention is necessary.
There are two major kinds of stroke. The most common is called an ischemic stroke, which are caused by a blood clot that blocks or plugs a blood vessel or artery in the brain. These types of strokes may be treated with a drug called t-PA, which dissolves blood clots, if patients receive care within 4.5 hours of the stroke.
The second major type of stroke is a hemorrhagic stroke, which is caused by a blood vessel in the brain breaking and bleeding into the brain. Hemorrhagic strokes cannot be treated with t-PA. Instead, surgery is often performed to help relieve the pressure or blood clots caused by this type of stroke. In both cases, time is of the essence for successful treatment.
There is another type of brain attack that may be a sign that an ischemic stroke is on the way. Transient ischemic attacks, or “mini-strokes,” happen when blood flow to the brain is temporarily blocked. Sufferers may experience blurry or lost vision on both eyes; tingling or numbness of the mouth, or are unable to speak clearly. The effects of TIAs may last only a few minutes, but this does not mean they should be ignored. TIAs may be predictors of strokes. It’s estimated that about 15 percent of those who have a stroke first experienced a TIA.
Besides TIAs, there are other warning signs of a stroke. They include:
Remember, not every stroke sufferer will have all of these signs, and sometimes the symptoms will go away only to return again. Call 911 right away if you or someone you know has one or more of these symptoms. The sooner medical treatment is given, the better the chances for survival and healing.
