Cerebral blood flow - a vascular system, blood circulation in the brain and spinal cord. The pathological process that causes stroke, can also affect the brain and the main artery (brachiocephalic trunk, the aorta, external and internal vertebral, carotid, subclavian, spinal, radicular arteries and their branches), jugular vein and brain, venous sinuses. Pathology in nature may be different: embolism, thrombosis, looping and excesses, aneurysm spinal cord and brain, narrowing.
Signs of cerebral circulatory disorders
Signs of proper blood circulation in the brain morphological character are divided into diffuse and focal. To diffuse grounds include small organizes and fresh foci of necrosis of brain tissue, multiple small focal changes in brain matter, small cysts and hemorrhage, gliomezodermalnye scars; a focal - cerebral infarction, hemorrhagic stroke, intrathecal hemorrhage.
By the nature of cerebrovascular accidents are divided into acute (intrathecal hemorrhage, transient, strokes), and the initial stages of chronic disorders of the spinal and cerebral blood flow (encephalopathy and myelopathy).
Symptoms of cerebral circulation
Initially, the disease may be asymptomatic. But in the absence of proper treatment of a rapidly progressing. Symptoms of cerebral circulation as follows:
• headache. This is the first symptom of circulatory disorders in the brain. If headaches become systematic, it should without delay consult a doctor.
• Dizziness. To the doctor should contact immediately if dizziness occur more than three times a month.
• Pain in the eyes. Pain in the eyes with the blood circulation in the brain tends to grow during the movement of the eyeballs. Most often, there is such a pain at the end of the day, when your eyes are tired of the stress throughout the day.
• Nausea and vomiting. To the doctor should contact if nausea and vomiting occur in conjunction with headache, dizziness and eye pain.
• Convulsions. Seizures may be of different types. As a rule, there are rarely enough.
• Nasal ringing and tinnitus. When circulatory disorders in the brain there is a feeling as if the ears exposed to water.
• Numbness. Those who have a cerebrovascular accident can onemevat hands, feet or other body parts. Numbness arise not as usual, after a long stay in an uncomfortable position, and for a reason. This is a direct consequence of disruption of blood circulation in the brain.
Acute ischemic attack
Acute circulatory disorder in the brain can be persistent (cerebral stroke) and transient.
Transient ischemic attack occurs because of a hypertensive crisis, cerebral vasospasm, cerebral arteriosclerosis, arrhythmias, heart failure, collapse. The symptoms of transient ischemic attack may occur as a few minutes or a whole day.
Treatment of cerebrovascular accidents
Treatment of cerebral circulatory disorders is to normalize cerebral blood flow in the tissue, stimulation of metabolism in neurons, treatment of major cardiovascular diseases, protect neurons from cerebral hypoxia factors.
Prevention of circulatory disorders in the brain is quite simple. To avoid disturbances it is necessary:
• Do not smoke or use psychotropic substances;
• to live an active lifestyle;
• Reduce salt intake;
• Monitor and maintain normal body weight;
• control the level of glucose content of lipoproteins and triglycerides in the blood;
• To treat existing diseases of the cardiovascular system.
