Basic Signs of Stroke

Many of us are genuinely surprised to learn thatthe first manifestations of disturbances in the work of cerebral circulation appear long before the onset of retirement age. Already in adolescence and adolescence, when our intensively growing body is shaken by hormonal storms, "points", "spots", "white flies", nausea and headaches appear before the eyes. All these are signs of a disturbed cerebral blood supply, but fortunately, at this age, such ailments are not dangerous and go away by themselves. In adulthood, cerebral blood supply disorders to many of us return under the name of vegetative-vascular (neurocirculatory) dystonia, or the so-called neurosis of the heart, from which only one step to the first manifestations of insufficiency of cerebral blood supply and stroke.

What is a stroke, what are the causes and symptomsstroke? So, stroke is an acute, sudden violation of the blood circulation of the brain, in which the blood flow through the artery is completely or partially blocked. An extensive stroke often results in a fatal outcome. The larger the damaged vessel, the larger the stroke. The most common cause of this is a blockage of the clot (thrombus) of the artery, which supplies the brain with blood. Such clots most often occur with atherosclerosis. Another cause of stroke is cerebral hemorrhage or in other words bleeding in the brain, which most often occurs in patients with atherosclerosis, suffering from the same high blood pressure.

There are following types of strokes: hemorrhagic and ischemic. With ischemic impairment of cerebral circulation occurs due to occlusion of the vessel, and with hemorrhagic - vascular rupture and hemorrhage in the brain tissue. Both ischemic and hemorrhagic stroke, develop against a background of such diseases as cerebral atherosclerosis, heart defects, hypertension, atrial fibrillation, heart failure and paroxysmal tachycardia.

Among all cases of stroke dominateischemic cerebral circulation, which account for up to 86% of cases, cerebral hemorrhage - up to 24% of cases, the rest - non-traumatic subarachnoid hemorrhage. Currently, stroke is becoming the main social and medical problem, annually in the world about 6.5 million people suffer a cerebral stroke. Among people who survived after this disability is 70-80%, of which 20-30% need constant care. Stroke is one of the main reasons for increasing the number of disabled people in the population.

Depending on the species, its developmentis accompanied by a number of symptoms. So, ischemic stroke, as a rule, is formed within 1,5-2 hours, however, in the case of embolism, its onset can be sharp, sudden. Hemorrhagic - often has a sharp, acute onset, accompanied by loss of consciousness or its confusion, vomiting and headache. In addition, the signs of a stroke depend on which region suffered from hemorrhage or ischemia. If changes occur in the left hemisphere of the brain, signs of a stroke appear on the right side of the body, and vice versa. For example, in the case of damage to the frontal lobes, personality changes, behavioral disorders with poor control of emotions, and damage to the left hemisphere, entail a violation of the functions of the speech center.

This is an emergency, so if on facesigns of a stroke, it is necessary to urgently call an ambulance and deliver the patient to a hospital. To wait for the arrival of an ambulance the patient must, having taken a horizontal position, the room in which he is to be ventilated. Also it is necessary to unbutton clothing, making it difficult to breathe, to remove from the mouth vomit and prosthesis.

Transportation of a patient with a stroke is alwaysis made lying, with the exception of the state of coma of the third stage, in which the patient is not transportable. Directly from such a condition, patients die rarely, bedsores and pneumonia often join the stroke, which require constant care, overturning, changing clothes, cleaning the bowels, feeding and vibromassage of the chest.
