Stroke - impaired blood circulation in the brain, causing the death of brain tissue. Reason: hypertension, atherosclerosis, vasculitis, aneurysms, vascular anomalies brain and blood diseases. Stroke is divided into hemorrhagic (bleeding in the brain, under the shell and the ventricles of the brain) and ischemic (thrombosis or embolism cerebral vessels and necropotence softening in the pathology of carotid and vertebral arteries).
Hemorrhagic stroke occurs due to the rupture of the pathologically changed cerebral vessel or by passage of red blood cells through the vascular wall. Hemorrhagic stroke is usually develops suddenly, often the day after mental or physical overstrain.
Symptoms: sudden loss of consciousness (the patient falls and sometimes gets bruises), crimson face, sweat on his forehead, pulsation of the neck vessels, breathing hoarse, loud, roaring, high blood pressure, heart rate stressful, rare, sometimes vomiting. Eyeballs are often rejected in the direction of the lesion, rarely in the opposite direction of the hearth; sometimes there floating eye movements. On the side of hemorrhage sometimes extends the pupil. Paralysis of upper and lower limbs on the side opposite the hearth of a brain hemorrhage. On the side of paralysis lifted the lid goes slower and the eyeball is closed incomplete (symptom Bogolepov), when breathing cheek take the rap in the form of the "sails", nasolabial fold smoothed, a paralyzed arm falls like a whip.
Stop on the side of paralysis turned outwards (symptom Bogolepov). With extensive bleeding in the brain in healthy limbs are observed automated traffic type gestures. When it breaks through the blood brain ventricles arise tonic spasms in the lower and upper extremities. In blood leukocytosis. The temperature rises. The symptoms of stroke depend on localization (in the cerebral hemispheres, the trunk, the cerebellum), size of tumor, the speed of development of a stroke.
Ischemic stroke (infarction of the brain) occurs more frequently in atherosclerosis of cerebral vessels, stenosis of the main vessels (sleepy, vertebrates), lowering blood pressure, increasing coagulation properties of the blood (increased content of prothrombin). Ischemic stroke is caused by the clogging of brain vessel thrombus or embolus or spasm of the cerebral vessels.
Ischemic stroke is usually preceded by headache, dizziness, staggering when walking, pain in the heart, transient weakness or numbness of the extremities, fainting. Ischemic stroke develops gradually, often at night or in the morning with a short-term loss of consciousness, but consciousness may not be violated. The man's face pale, weak pulse, blood pressure is lowered, the heart activity and respiration is weakened, heart sounds deaf, when retinoscopy artery narrowed in increased blood protrombina index, specific gravity of urine low. Ischemic stroke due to cerebral embolism vessels observed in septic endocarditis, rheumatic heart disease, myocardial infarction with parietal clot, with the development of atrial fibrillation and is characterized by short-term loss of consciousness, epileptiform seizures, dizziness, weakness in the limbs, often in one. The face is pale, pulse quickened and arrhythmic. There is a fever low grade fever. Borders of heart expanded, auscultation - systolic murmur. Blood pressure does not rise. Often there is a combination with infarctions of other bodies.
For stroke has three options: 1) favorable, when gradually restored completely broken functions; 2) alternating, which periodically the condition of the patient deteriorates in connection with the acceding pneumonia, recurrent strokes or other complications, but with a favorable outcome, although it is noted insufficiently full restoration of disturbed functions; 3) progressive, with a gradual worsening of symptoms and death. The recovery of consciousness under favorable period is a few minutes or hours, with progressive - in 2-3 days. If the consciousness is not returned after 3 days, the forecast becomes heavy.
