Stroke — is a heavy and very dangerous stroke, which eventually causes the death of brain tissue due to lack of adequate nutrition in the brain, resulting in damaged brain and is blockage or rupture of the brain.
Causes of stroke
The most common cause of stroke — cerebral thrombosis, occlusion of blood clot (thrombus) of arteries supplying the brain. There is a clot (plaque) mostly in atherosclerosis.
Another cause of stroke — bleeding in the brain, internal bleeding in the brain. Artery of the brain affected are can rupture (break) and flood the blood surrounding the brain tissue. Cells were fed by the artery, are not able to receive blood and oxygen.
Hemorrhage in the brain is more likely to occur when the patient experiences both atherosclerosis and high blood pressure.
In other words, the cause of stroke is damage to nerve cells in the brain and controls all functions of the human body. And this kind of damage, and more precisely, the death of nerve cells occur due to acute circulatory disorders in a particular part of the brain when it is highly active cells suddenly cease to be necessary and sufficient for them of blood. As a result, blood is not flowing through the vessels, brain cells die, the commands to the muscles is not received, which ultimately leads to
types of stroke
There are two types of stroke: hemorrhagic stroke (vessel rupture and hemorrhage) and ischemic stroke (blockage of the vessel). And most of all as a hemorrhagic stroke and ischemic stroke, occur against a background of hypertension, heart disease (atrial fibrillation, vices, paroxysmal tachycardia), heart failure, cerebral arteriosclerosis.
