What is a Stroke
Stroke is a “Brain Attack”, cutting off vital blood flow and oxygen to the brain. In the U.S., Stroke is the third leading cause of death, behind heart disease and cancer, killing 170,000 people each year, and the leading cause of adult disability. Approximately 780,000 strokes will occur this year; however 500,000 of those strokes can be prevented. Stroke can happen to anyone at any time, regardless of race, sex or age.
Types of Stroke:
Ischemic stroke occurs when arteries are blocked by blood clots or by the gradual buildup of plaque and other fatty deposits. Almost 85 percent of all strokes are ischemic. Hemorrhagic stroke occurs when a blood vessel in the brain breaks leaking blood into the brain. Hemorrhagic strokes account for about fifteen percent of all strokes, yet are responsible for more than thirty percent of all stroke deaths. Two million brain cells die every minute during stroke, increasing risk of permanent brain damage, disability or death. Recognizing symptoms and acting fast to get medical attention can save a life and limit disabilities.
Few Americans know the symptoms of stroke. Learning them could save your life or the life of a loved one.
Common stroke symptoms include:
- Sudden confusion, trouble speaking or understanding
- Sudden trouble seeing in one or both eyes
- Sudden trouble walking, dizziness, loss of balance or coordination
- Sudden severe headache with no known cause
- Sudden numbness or weakness of the face, arm or leg – especially on one side of the body
This simple test will help you detect stroke symptoms and Act F.A.S.T.:
F = FACE Ask the person to smile. Does one side of the face droop?
A = ARM Ask the person to raise both arms. Does one arm drift downward?
S = SPEECH Ask the person to repeat a simple sentence. Does the speech sound slurred or strange?
T = TIME If you observe any of these signs, it’s time to call 9-1-1 or get to the nearest stroke center or hospital
KNOW YOUR NUMBERS
- Know your BLOOD PRESSURE. If it is elevated, work with your doctor to keep it under control. High blood pressure is a leading cause of stroke. Have your blood pressure checked at least once each year – more often if you have a history of high blood pressure. Your blood pressure should be 120/80 or under.
- Find out if you have ATRIAL FIBRILLATION (A-FIB). If you have A-FIB, work with your doctor to manage it. Atrial fibrillation can cause blood to collect in the chambers of your heart. This blood can form clots and cause a stroke. Your doctor can detect A-FIB by carefully checking your pulse.
- If you smoke, stop. SMOKING doubles the risk for stroke. If you stop smoking today, your risk for stroke will begin to decrease.
- If you drink alcohol, do so in moderation. Having one drink each day may lower your risk for stroke (provided that there is no other medical reason you should avoid alcohol). Remember that alcohol is a drug – it can interact with other drugs you are taking, and alcohol is harmful if taken in large doses. If you don’t drink, don’t start.
- Know your CHOLESTEROL number. If it is high, work with your doctor to control it. Lowering your cholesterol may reduce your risk for stroke. High cholesterol can also indirectly increase stroke risk by putting you at greater risk of heart disease – an important stroke risk factor. Often times, high cholesterol can be controlled with medication. Your total cholesterol should be less than 200.
- Control your DIABETES. If you are diabetic, follow your doctor’s recommendations carefully. Having diabetes puts you at an increased risk for stroke. Your doctor can prescribe a nutritional program, lifestyle changes and medicine that can help control your diabetes. Your blood glucose level should always be between 60-100.
- Include EXERCISE in the activities you enjoy in your daily routine. A brisk walk, swim or other exercise activity for as little as 30 minutes a day can improve your health in many ways, and may reduce your risk for stroke.
- Enjoy a lower SODIUM(salt), lower fat diet. By cutting down on sodium and fat in your diet, you may be able to lower your blood pressure and, most importantly, lower your risk for stroke.
- Ask your doctor if you have CIRCULATION problems. If so, work with your doctor to control them. Fatty deposits can block the arteries which carry blood from your heart to your brain. Sickle cell disease, severe anemia, or other diseases can cause stroke if left untreated.
- If you have any stroke symptoms, seek immediate medical attention immediately. Stroke is medical emergency and you need to dial 9-1-1.
