The term "stroke" comes from Latin, literally - jump or hop like. Medicine explains this process as an acute disturbance of cerebral blood circulation, which is always accompanied by damage to its tissues and its dysfunction.
Common causes of this disease can be atherosclerosis, hypertension and rheumatism, blood diseases, heart disease. Treatment of stroke includes a number of measures, this is a long and complicated process. Leonie depends on the type of stroke.
Types of strokes:
Hemorrhagic. Represents a cerebral hemorrhage, occurring against a background of hypertension. Often the impetus for the development of hemorrhage in the brain are physical exertion, emotional upset.
Blood partially destroys and compresses the surrounding brain nervous tissue, causing swelling of the whole brain. Stroke is accompanied by vomiting, disorder of heart rhythm, breathing and loss of consciousness. When bleeding the person often becomes purple color appears seizures of various kinds. And possible paralysis of the upper or lower extremities, impaired tactile features, speech features.
Ischemic. Essentially ischemic stroke is a softening and relaxation of the tissues of the brain, i.e., a kind of cerebral infarction. This process develops at the time of occlusion of cerebral vessels by atherosclerotic plaque, thrombi, emboli. A thrombus is a blood clot, and the embolus is part of the plaque or thrombus. Ischemic stroke can occur if the flow of blood to a specific area of the brain, due to the fact that when the atherosclerotic process area narrows. When this occurs the lack of oxygen and nutrients to the site along with its tributaries blood. Tissue area softened, and functionality of the area of the brain dies.
The development of this type of stroke may contribute to a drop in blood or heart pressure, weakening of the heart functions and activities of the heart, increased blood clotting. Predecessors are the breach and weakness of the limbs, impaired brain circulation, numbness of parts of the body, disorders of speech functions. Unlike hemorrhagic, ischemic stroke, face pale and dull. Experiencing paralysis, speech disorders, disorders of sensory function.
To avoid the above diseases, it is necessary to consult the doctors with any of the described syndromes, as well as for the purpose of preventive measures.
