Knowing the signs of a stroke is the first step in stroke prevention.
A stroke, sometimes called a "brain attack," occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die. If not caught early, permanent brain damage can result.
Lots of things affect whether you get heart disease, and you control many of them. Little things you do every day can make a difference.
1. Unwind and connect. Cut out as much stress as possible. Find ways to ease the stress you can't avoid. Exercise, meditation, and talking to people you trust are three ideas to start with.Work on your weight. Most Americans are overweight. Bringing your weight to a healthy level is a plus for your heart.
2. Upgrade your next meal. Favor fruits, vegetables,...
Ischemic stroke is similar to a heart attack, except it occurs in the blood vessels of the brain. Clots can form either in the brain's blood vessels, in blood vessels leading to the brain, or even blood vessels elsewhere in the body which then travel to the brain. These clots block blood flow to the brain's cells. Ischemic stroke can also occur when too much plaque (fatty deposits and cholesterol) clogs the brain's blood vessels. About 80% of all strokes are of this nature.
Hemorrhagic (heh-more-raj-ik) strokes occur when a blood vessel in the brain breaks or ruptures. The result is blood seeping into the brain tissue, causing damage to brain cells. The most common causes of hemorrhagic stroke are high blood pressure and brain aneurysms. An aneurysm is a weakness or thinness in the blood vessel wall.
What Are the Symptoms of a Stroke?
The most common symptoms of a stroke are:
Weakness or numbness of the face, arm, or leg on one side of the body.
Loss of vision or dimming (like a curtain falling) in one or both eyes.
Loss of speech, difficulty talking or understanding what others are saying.
Sudden, severe headache with no known cause.
Loss of balance or unstable walking, usually combined with another symptom.
What Should I Do If I Experience Stroke Symptoms?
Immediately call 911 if you or someone you know shows the symptoms of a stroke. Stroke is a medical emergency. Immediate treatment can save your life or increase the chances of a full recovery.
Are Strokes Preventable?
Up to 50% of all strokes are preventable. Many risk factors for stroke can be controlled before they cause problems.
Gender (Men have more strokes, women have deadlier strokes)
Race (African-Americans are at increased risk)
Family history of stroke
Your doctor can evaluate your risk for stroke and help you control risk factors. Sometimes, people experience warning signs before a stroke occurs.
These are called transient ischemic attacks (also called TIA or "mini-stroke") and are short, brief episodes of the stroke symptoms listed above. These can also been warning signs of an impending major stroke. Anyone with a TIA needs to be taken to the emergency room. However, some people have no symptoms warning them prior to a stroke or symptoms are so mild they are not noticeable. Regular check-ups are important in catching problems before they become serious. Report any symptoms or risk factors to your doctor.
