Thus the notion of joining strokes, which are divided into ischemic and hemorrhagic. Ischemic be caused by blood flow to the region of the brain due to clogged arteries, which nourish this area, with the help of a thrombus, or atherosclerotic plaque. The second stroke is caused by the shedding of blood in the brain, which is usually associated with a gust of arteries, deeply disturbed atherosclerotic process. Thus, atherosclerosis is the main reason that violates the cerebral circulation. During the stroke of the brain dies, and the functions that controls this area, is impossible. Provision is more transient changes in cerebral blood flow associated with short-term blood circulation due to spasm of cerebral blood vessels. At the same time signs of lack of functions not last for more than a day and completely returned. This type of changes in cerebral blood flow can be regarded as a kind of bell - if no action is taken, stroke is not very far. Symptoms of stroke depend on which part of brain tissue affected. Can fall out the following functions: body movement (in any arm or leg, both arms or both legs, arm and leg on one side, the upper limbs on one side and the lower limb - on the other, and sometimes, once in all limbs at once) ; tactile sensations (sense of touch, pain, thermal sensitivity, etc.) in different parts of the body; vision; hearing; opportunity to talk to (variants: the person is able to easily pronounce any sounds, but it is meaningless, that articulation is preserved, but there is no formation of speech has the opportunity to talk, but he does not understand speech did not, because the language does not move as well as the lips, etc.); The evidence provided (not very complete on the number of variations) of cases shows that the manifestations of stroke are very diverse, based on combinations of these features neurologists can specify exactly which piece of the brain struck. When a stroke occurs, some of the cells are killed, while another portion is in the zone of damage, although not fatal. After a while, when it comes to normal circulation, these cells begin to work, and some functions are restored. The problem of doctors in the treatment of stroke is reduced to the maximum full correction of blood circulation in the brain in order to preserve all the cells, balancing on the border of life and non-existence. Prevention of circulatory disorders is reduced to the prevention and cure of atherosclerosis and arterial hypertension. Treatment of acute stroke is carried out in the hospital, because in this disease state is possible, life-threatening. Houses provide treatment results circulatory disorders in the brain.
