Definition of stroke
The brain has many blood vessels to nourish it. When blood vessels are clogged, we call it cerebral infarction, and when blood vessels burst, we call it cerebral hemorrhage. If the brain is damaged by blocked or burst blood vessels, we call it a stroke.
Symptoms of a stroke symptom
First, a sudden headache occurs. I can't walk and I'm so dizzy that I can't even walk.
When I try to force myself to get up and walk, my body won't listen and keeps stumbling. It differs slightly from simple dizziness (dizziness symptoms) and dizziness, and is accompanied by most of the other premonitory symptoms. Second, things can be overlapped in two, or one view can be blurred. It feels different from presbyopia or visual diseases caused by aging, and it is also a characteristic symptom of stroke. Third, one leg or arm feels heavy, accompanied by paralysis, and one-sided paralysis occurs. It is similar to the feeling of cramping in the arm, symptoms of neck disc, and carpal tunnel syndrome, but different, and suddenly, while eating, your shoulders, arms, and hands become weak, loosened, and you drop your spoon repeatedly. The symptoms of loss of strength in both arms are not pre-stroke symptoms, and the characteristic of stroke is that the right or left side of the body loses strength or paralysis. Fourth, when you talk or talk, you have symptoms of strong pronunciation and dull pronunciation as if you were drunk from drinking. There is a language disorder phenomenon that does not fit the situation, says wrong things with the communication content of the conversation, deviates from grammar, and says strange babbling. Fifth, I have a headache with severe pain intensity that I've never experienced in my life. It's not just a headache like a simple headache, but it can cause vomiting because it hurts your forehead or brain as if it's about to rip. It's different from the headache and heavy symptoms.
How to diagnose stroke
If a stroke is suspected through the patient's symptoms, a brain CT computed tomography is performed. Another test is two MRI scans, which are brain magnetic resonance. If you look closely at the two tests, you can distinguish whether the blood vessels in your head are blocked or ruptured by CT scans, a brain computed tomography, in a short time. However, CT scans can miss very small cerebral hemorrhages, especially if blood vessels are blocked, they often do not come out well within a day or two. In this case, brain computed tomography or magnetic resonance imaging may be required again later to accurately identify the brain lesion area of cerebral infarction. Brain CT computed tomography allows you to easily distinguish areas with cerebral infarction and areas with cerebral hemorrhage, and if you take a contrast medium through CT scans, you can also observe cerebrovascular system.
Brain magnetic resonance imaging has a very high resolution compared to brain CT computed tomography. So it's a test that can detect small kinds of strokes or even small strokes in the stem brain. Because it takes longer to perform an examination than CT, and it is difficult to film if you move, it may be difficult to take pictures for critically ill or unconscious patients. Among the brain magnetic resonance images, the image that is often used in recent stroke patients is the diffusion-enhanced image. It is a method of performing brain MRI using water molecule movement, and it is a good imaging technique that helps to accurately identify strokes that occur within a few minutes, which are difficult to detect with general brain magnetic resonance images. Vascular imaging tests that allow you to see blood vessels in the brain using brain magnetic resonance images are also available.
a stroke prevention method
Since it is most important to prevent strokes from occurring in advance, it is most important to identify abnormalities in cerebrovascular systems through usual health checkups and provide preventive treatment. First of all, a cerebrovascular test is performed to check for abnormalities in cerebrovascular vessels, and if there are abnormalities in cerebrovascular vessels, take appropriate procedures or drugs. However, even if there are no abnormal findings in cerebrovascular examination, the risk of stroke can be reduced by removing risk factors that increase the occurrence of stroke.Among these risk factors, factors such as age, family history, race, and gender cannot be controlled, but high blood pressure, diabetes, hyperlipidemia, smoking, heart disease, obesity, and drinking are known as risk factors for stroke that can be controlled in advance.
The most representative risk factor is high blood pressure. In particular, persistent hypertension is the most important risk factor for ischemic and hemorrhagic strokes because it causes damage to the walls of blood vessels and causes arteriosclerosis.High blood pressure patients often refuse to take blood pressure drugs once they start taking them for life, but considering the fact that leaving high blood pressure alone increases the risk of stroke in the future, it is necessary to control them thoroughly from the beginning. Diabetes and hyperlipidemia also damage blood vessels, increasing the risk of stroke. In particular, appropriate treatment is essential because it can increase the risk of stroke if you have been spending a long time without knowing if you have diabetes or hyperlipidemia, or if you know and leave it without proper treatment.Smoking also increases the incidence of stroke, so smoking cessation is essential to prevent stroke. In particular, heart diseases such as atrial fibrillation and heart valve disease are also important risk factors. In this case, blood hardens in the heart wall, making it easy to form clotted blood clots, which can fall off and block cerebrovascular vessels. Most of the causes of stroke like this are bad lifestyles or chronic diseases. Bad lifestyle habits increase the risk of stroke by causing diseases that cause stroke as well as stroke itself, so it is necessary to correct bad lifestyle immediately and prepare for healthy old age by constantly controlling chronic diseases that cause stroke.
