called cerebral circulation the movement of blood through the vessels of the brain and spinal cord.The pathological process that causes stroke, characterized by lesions of the brain and the major arteries of the brain, and the jugular veins and venous sinuses.Pathology of cerebral vessels are different: thrombosis, bends and looping, embolism, luminal narrowing, aneurysms of vessels.The concept of cerebral vascular insufficiency as a whole can be defined as a discrepancy between the amount of the necessary amount of blood to the brain and its actual delivery.

Causes of cerebral circulation

The causes of violations primarily include atherosclerotic vascular disease.Atherosclerosis is called disease, in which plaque is formed, which prevents the normal passage of blood through the narrowing in the vessel lumen.This plaque can event

ually grow in size, accumulating platelets.As a result of a blood clot is formed that is either completely encloses a lumen, or breaks off and is carried away by the blood to the brain, clog them, causing a stroke, that is, to the acute stroke.

Another cause of the disease is considered to be high blood pressure, since many hypertensive patients are often not serious about his condition when the pressure increases and the treatment of this disease.

Like any organ, the brain needs a good rest.If a person is excessively loads his work, gradually the brain gets tired and exhausts all the resources.Chronic tiredness can also be attributed to the causes of circulatory disorders in the brain.Osteochondrosis of the cervical spine due to the clamping of the arteries supplying the brain violates its blood supply and function.

Such a head injury, a concussion, bruises and bleeding, do not pass unnoticed.They cause a compression of the brain centers that disturbs cerebral circulation, which, in turn, can lead to death.

Types of violations

There are two types of cerebral circulation: chronic and acute.Acute cerebrovascular accident (CVA) is always evolving very quickly - in a matter of hours or even minutes.

stroke is divided into stroke and transient ischemic attack:

  • Hemorrhagic stroke - a condition which is caused by bleeding in the tissue at break of the vessel under the influence of some factors;
  • Ischemic stroke - a cerebral hypoxia, which developed after the closure of the lumen of a blood vessel supplying the site;
  • transient ischemic attack are local circulatory disorders of the brain, which usually do not affect vital areas and do not cause serious problems.

chronic disturbances of brain circulation developing over the years.At the initial stage, the symptoms do not usually appear, but they are expressed in the progression of the disease.

Symptoms of cerebral circulation

Symptoms of stroke will have a different picture in each form of the disease, but a similar clinic disorders of the brain function.

Symptoms of cerebral circulation are different:

  • subjective dizziness, headache, tingling and "pins and needles";
  • violation of the motor function of the body: paresis (partial immobilization of the limb) and paralysis (complete loss of movement of any part of the body);
  • reduction functionality senses (hearing or vision);
  • violation sensitivity (weakening, loss or pain);
  • any changes in the cerebral cortex: a violation of the letter, a speech, loss of the ability to read the problems, etc .;
  • seizures;
  • decline in mental abilities, intelligence, memory, distraction.

Each of cerebral circulation has its own characteristics:

  • When ischemic stroke symptoms of cerebrovascular accidents always occur acutely.With this illness there are subjective complaints of the patient, may be nausea and vomiting, as well as focal symptoms, which is a change in the system or organ that is responsible for the damaged area of ​​the brain.
  • Hemorrhagic stroke occurs when blood enters from damaged blood vessels in the brain cavity with its further squeezing and thus dangerous complication as impaction of the brain stem in the foramen magnum.This disease is a leader in the number of deaths among all types of cerebral circulation.
  • Transient ischemic attack (TIA) is a transient ischemic attack, which eventually passes.It is accompanied by paresis, speech and visual function, sleepiness and confusion.
  • chronic disorders of brain blood flow observed in the elderly and is characterized by the gradual development over the years.Characteristic symptoms: decreased intelligence, mental ability and memory.Such patients are scattered and sometimes aggressive.

Diagnosis The diagnosis is put on the basis of the following symptoms:

  • patient's specific complaint for the violation;
  • availability of patient factors that contribute to the development of circulatory disorders: diabetes, high blood pressure, atherosclerosis;
  • duplex scanning - identification of the affected vessels;
  • magnetic resonance imaging (MRI) - visualization of brain lesion, the most informative study of the disease.

Treatment of cerebrovascular

acute stroke requires emergency care specialists.Stroke care should be aimed primarily at maintaining the functionality of vital organs.The base treatment of cerebrovascular includes providing the patient the correct blood circulation and breathing, reduced brain edema, correction fluid and electrolyte disturbances, as well as the normalization of blood pressure.Such procedures must be performed in a hospital.

Subsequent treatment of disorders of cerebral circulation is the elimination of the causes which has instituted the disorder as well as restoration of the disturbed functions and blood flow in the brain.

chronic circulatory disorder is usually treated with medications that improve blood flow in the arteries and blood rheology.Also carried out the normalization of blood pressure and blood cholesterol.Normalization of brain blood circulation prevents the development of stroke and other serious diseases of the cardiovascular system.So, together with procedures, physicians often prescribe drugs for the treatment of vascular disorders.For example, a combined preparation Vazobral metabolism and improves blood circulation in the brain.The components of the drug to prevent blood clots, reduces the permeability of vessel walls, increases the resistance of brain tissue to the lack of oxygen, improve mental and physical performance.Clinically proven efficacy of the drug in preventing headaches.

Reading books, training of memory and intellectual abilities also help slow down the progression of the process.Unfortunately, completely restore all lost functions no longer work, but in your power to not let the situation worsen.
