At a stroke (cerebrovascular accidents) in certain parts of the brain blood flow is reduced or completely eliminated. Stroke is a major cause of the deterioration of brain function in adults. There are two types of strokes.
Ischemic stroke (cerebral circulation on ischemic type) occurs when a blood clot blocks an artery or capillary in the brain, 80% of strokes are ischemic. The second type of hemorrhagic stroke (cerebrovascular accident on the hemorrhagic type) occurs when the brain bursts a blood vessel and bleeding occurs.
In both cases, the damaged area of ??the brain cells no longer receive oxygen and nutrients they need in sufficient quantity and begin to die. Because of this, a person loses the ability: to move, speak, see, breathe.
Stroke - the second (after coronary heart disease) cause of death in many countries. A fifth of patients after stroke are severe disabilities. But many impacts can be avoided, if the time to call the doctor.
The first 3-6 hours after a stroke - a "therapeutic window" - a time in which medical care is most effective.
