A stroke is called a circulatory disturbance in the brain. By their appearance, stroke can be divided into ischemic and hemorrhagic. In order to help the victim in time, it is important to know the symptoms of a cerebral stroke and be able to provide the necessary assistance at their first manifestations.
Hemorrhagic stroke of the brain is most often the result of hypertension. With a hemorrhagic stroke , a blood vessel ruptures in the brain, the blood from which enters the brain and compresses it. A vessel can also burst during aneurysm, when a thinned bulging place forms in it that does not withstand pressure. Further, cerebral edema occurs, and the affected area is necrotic.
In addition to the above reasons, hemorrhage may be due to the weakening of the walls of blood vessels from exposure to stably high pressure. The walls become loose, porous, and blood flows out of these pores.
In ischemic stroke, the reason lies in the presence of an atherosclerotic plaque, which closes the blood vessel for free blood flow. A similar mechanism also works in the presence of blood clots - then vascular thrombosis occurs. As a result, the clogged area receives neither nutrition nor oxygen. As a result of this, asphyxia and necrosis of brain tissue occur. And despite the fact that the vessel does not lose its integrity, its functions to ensure the viability of brain regions are reduced to zero. The factors that contribute to vasospasm and their further blockage include constant stresses that overwhelm the life of a modern person, overwork at work, bad habits (alcohol, tobacco smoking, drug use), metabolic disorders and, as a result, overweight, fluctuation of indicator blood sugar, poor ecology.
Symptoms of a brain stroke are difficult to recognize immediately. The processes that occur in the brain are instantly displayed on a person’s behavior and well-being. But sometimes with a mild stroke, people do not attach importance to this, attributing the disease to headaches or overwork.
To properly diagnose the disease, you need to know the symptoms of a brain stroke. So, the first thing that manifests itself in a stroke is a difficult coordination in movements or even numbness of some parts of the body. At the same time, people often can’t talk in a coherent manner about their condition - their speech is disturbed, they can confuse words, change their places involuntarily, making speech obscure to others, make incomprehensible sounds. Visual perception also suffers - victims see "flies in front of the eyes", a bifurcation of objects. Severe cases are accompanied by vomiting and nausea. With a hemorrhagic stroke, patients complain of a red veil in front of the eyes. Typically, these symptoms are most visible on one half of the body.
If others notice such symptoms of a brain stroke, it is important to call an ambulance right away. Further treatment of cerebral stroke is carried out after hospitalization in a medical institution. For such patients, a wide rehabilitation program is provided, since removal from a critical condition is only half the battle. The rest remains to be done in terms of returning the insulin to normal life.
Usually, if there is a predisposition to stroke (this is determined on the basis of screenings), it is important to operate on the affected area. For example, if an aortic aneurysm is detected, it is better not to wait for it to burst, but to immediately remove the affected area of the vessel.
In any case, the risk of stroke increases by middle and old age, so you should limit the impact of negative factors, stay more in the air, exercise, eat healthy food.
