At a stroke (cerebral circulatory disorders) in certain parts of the brain blood flow is reduced or stopped altogether. Stroke is a major cause of deterioration of brain function in adults. There are two types of strokes. Ischemic stroke (cerebrovascular accident on the ischemic type) occurs when a blood clot blocks an artery or a capillary in the brain, 80% of strokes are ischemic. The second type of hemorrhagic stroke (cerebral blood flow in hemorrhagic type) occurs when the brain blood vessel bursting and bleeding occurs. In both cases, the damaged area of the brain cells no longer receive oxygen and nutrients they need in sufficient quantities and begin to die.

Causes of Stroke

The cause of stroke is a violation of the blood flow to certain areas of the brain due to blockage (stenosis) or rupture of cerebral arteries.

The cause of obstruction may be:

- Embolism (blood clot breaks away when the place of education and enters the bloodstream to the arteries of the brain, most often in sleeping);
- Thrombosis (the formation of a blood clot in the vessels of the brain, usually due to atherosclerosis);
Causes of cerebral artery rupture and hemorrhage are:
- Hypertension;
- Congenitally weak artery walls, such as an aneurysm;
- Serious injury (such as a severe blow to the head during a traffic accident).

Symptoms of Stroke

When you see the following symptoms should immediately call an ambulance:

- Occurrence of sudden weakness, numbness or paralysis of the muscles of the face, arm or leg, usually on one side of the body;
- Unusual difficulty or speech-impaired;
- Rapid deterioration of vision in one or both eyes;
- Unexpected gait disturbance, dizziness, loss of balance or coordination;
- Severe headache with no known reasons.

Short-term ischemic attacks are microstroke (transient transient cerebral ischemic attack). Symptoms of it are the same as that of the normal stroke but the duration of a few minutes. If you suspect yourself or your loved ones microstroke, you must seek immediate medical attention.


A stroke can lead to further prolonged coma, paralysis or paresis (muscle weakness) of the muscles on one side or part of the body, mentally and / or memory. Severe stroke can cause death.

What you can do?

If you are an observer, and you think that a man stroke, if after a head injury in humans marked vomiting or weakness, call an ambulance.

What can a doctor?

If you suspect a stroke, the patient must undergo a hospital examination and treatment.
In the diagnosis is commonly used computed tomography, magnetic resonance imaging and other studies.

You may need surgery to remove a blood clot, or hematoma, bleeding stops.
After a stroke, nearly all patients need rehabilitation. In restoring the lost stroke speech and motor skills may help moderate exercise, occupational therapy, and speech therapy.

Preventive measures

Regularly measure your blood pressure. If you suffer from hypertension, try to follow the doctor's recommendations and to control blood pressure. In ischemic heart disease obey diet and be active enough.

Control your blood sugar levels.
Give up smoking.
