How to Deal With Stroke

A stroke is a circulatory disorder in the brain caused by a blockage or rupture of blood vessels. This is a condition where a blood clot - a blood clot - or blood from a ruptured vessel disrupts blood flow in the brain. Lack of oxygen and glucose leads to the death of brain cells and impaired motor function, speech or memory.

What happens

Three-quarters of all cases of the disease - ischemic stroke. This term refers to a condition in which a thrombus clogs a vessel and blocks blood flow to a specific part of the brain.
Usually, a blood clot forms somewhere in the peripheral vessels of the body, breaks off and reaches the brain along the bloodstream. There he gets stuck in small vessels of the brain and blocks the blood flow in them.
The second type of stroke - hemorrhagic - is much less common. It occurs when a blood vessel is broken in the brain.

If the vessel is on the surface of the brain, leaked blood fills the space between the brain and the skull. This is called subarachnoid hemorrhage. And if the vessel breaks in the deeper structures of the brain, blood from it fills the surrounding tissues.

But the result of both types of bleeding is one - a violation of blood flow to the nerve cells and the pressure of accumulated blood on the brain tissue.

Effects of stroke

The defeat of a small area of ​​the brain leads to small violations - weakness of the limbs. Circulatory disorders in large areas of the brain cause paralysis and even death: the degree of damage depends not only on the scale, but also on the location of the stroke.

For many people who have suffered a stroke, one side of the body remains partially or completely paralyzed, and speech and control functions appear to control urination and bowel movements. Intellectual abilities also suffer - memory, cognitive functions.

Stroke symptoms

The onset of a stroke is usually asymptomatic. But after a few minutes, the brain cells that are deprived of food begin to die, and the effects of a stroke become noticeable.
Common symptoms of stroke:
· Sudden weakness in the face, arm or leg, most often on one side of the body;
· Sudden clouding of consciousness, problems with speech or with the understanding of speech;
· Sudden vision problems in one or both eyes;
· Sudden gait dysfunction
