Stroke is a serious disease in which the blood supply to a certain area of ??the brain is impaired. This leads to oxygen starvation of the brain region, as a result of which nerve cells located in the region with disturbed blood supply are damaged and die. Together with them, those functions of the body are violated, for which the affected area of ??the brain is affected by a stroke.

Increased emotionality in combination with low stress resistance in women leads to a higher risk of strokes.

Strokes occur both in men and in women, from young age to old age.

Causes of stroke The main immediate causes of strokes - compression or blockage of blood vessels, leading to ischemia, and cerebral hemorrhage. Depending on this, there are two types of stroke.

Hypertension is one of the most frequent conditions that increase the risk of stroke. Ischemic stroke - occurs due to blockage of blood vessels supplying blood to the brain, tearing off a thrombus or blood clot. In rare cases, the lumen of the vessel is clogged with fat particles or air bubbles (fat and air embolism), thrombi from the left ventricle of the heart. Also, the vessel can be squeezed by a tumor or scar, formed after an injury. As a result, the nerve cells blood-supply damaged by the vessel area cease to receive oxygen and nutrients. In a number of cases, neighboring arteries can take the blood supply to this part of the brain to themselves, but more often, if you do not take timely measures, nerve cells die. Ischemic stroke is the most common form of the disease, which accounts for more than 70% of all cases of acute cerebrovascular accident. According to the mechanism of development, ischemic stroke is similar to myocardial infarction, as well as it is accompanied by softening of the affected area of ??the brain substance, therefore it is also called a cerebral infarction.

Hemorrhagic stroke is a form of the disease, the cause of which is the rupture of the cerebral vessel and the release of blood into the brain tissue. In this case, the wall of the defective artery. The cause of cerebral hemorrhage may be an aneurysm or a violation of the integrity of the vascular wall due to atherosclerosis, and the provoking factor may be a sharp increase in blood pressure. As a result, blood accumulates, impregnates brain tissue and exerts pressure on them, thereby disrupting their normal vital functions and supplying oxygen. Occurs less often than ischemic stroke, but has a more serious prognosis.

The main causes of acute impairment of cerebral circulation in men - psychological factors, malnutrition, metabolic disorders, overweight and hypertension.

Prerequisites for a stroke may be transient ischemic attacks (TIA) - temporary disorders of cerebral circulation. Attack can happen in weeks or even months before the actual stroke. This is a micro-insult, in which blood circulation in the brain temporarily stops, so the signs of TIA are very similar to the symptoms of a stroke, but usually they completely pass within an hour. As a rule, the body can quickly restore normal blood circulation.

Different areas of the brain are responsible for different functions of the body - limb movements, speech, hearing, vision and t. The consequences of stroke and loss of vital functions directly depend on which part of the brain was damaged. This may be paralysis (complete loss of motor function) or paresis (partial impairment of movements) of the arm or leg on the side opposite to the lesion focus, speech and writing disorders, memory disorders, thinking, impaired sensitivity and other serious consequences.

In people of different sexes and ages, stroke has a similar developmental mechanism, but the consequences are individual for each patient.

Risk Factors There are factors that increase the risk of stroke in people of any gender and age. These include bad habits, unhealthy lifestyle, unbalanced diet, as well as diseases of the cardiovascular, endocrine and other systems.

The main risk factors for stroke related to lifestyle:.

Eating;.

Inadequate nutrition, which leads to cholesteremia - increased cholesterol in the blood and deposition on the walls of blood vessels, including cerebral vessels, atherosclerotic plaques;.

| Smoking;.

| Alcohol abuse.

Prerequisites for a stroke may be transient ischemic attacks (TIA) - temporary disorders of cerebral circulation. Attack can happen in weeks or even months before the actual stroke.

Diseases and pathological conditions, which are most often associated with acute impairment of cerebral circulation:.

| Arterial hypertension (high blood pressure);.

Heart diseases - pathologies of the heart valves, congenital heart defects, heart rhythm disturbances (arrhythmia);.

Atherosclerosis of cerebral vessels;.

Diabetes mellitus;.

| Aneurysms of cerebral vessels;.

Blood coagulability, changes in its rheological properties;.

| Dissection (dissection) of the cerebral arteries.
