Cerebral ischemia - the body's response to oxygen deprivation


Cerebral ischemia - the body's response to oxygen deprivationAny of the body portion, which would somehowany reason does not get enough food, it begins to gradually die off. It is caused by circulatory disturbance. If you have poor blood flow to organs do not receive enough oxygen and other necessary substances for normal functioning. This causes the gradual degeneration of the tissues and their eventual necrosis. This process is characteristic of the brain, when ischemia causes the progressive death of neurons.

The cause of such diseases asBrain ischemia is arteriosclerosis. Atherosclerotic plaque forming on the inner wall of the vessel, its narrow passage, disrupting the tissue trophism. Less commonly it may be blood clots which are in the lumen they relate and come off blood flow in vessels with a narrow lumen, blocking them.

Ischemia can trigger:

  • acute heart failure, myocardial infarction;
  • heart rhythm disorder;
  • blood clots, anemia, intoxication and other gas;
  • anomalies and changes in brain vessels.

The disease has two forms: acute and chronic brain ischemia.

The main symptoms of ischemic cerebrovascular

Ischemia of the brain blood vessels - a dangerous anda nasty disease that can lead to irreversible consequences. And in order not to aggravate the process, when the first signs of the disease should immediately go to the doctor and begin appropriate treatment as soon as possible. Ischemia can occur at any age - it all depends on comorbidity. Problems oxygen starvation can occur in newborns - during pregnancy or during birth. As a result of cerebral ischemia can develop neonatal brain.

The first signs of the disease are similar to symptoms of other diseases, and so, in time to find out exactly what is happening to your body, it should be examined immediately.

Heralded beginning of ischemia are:

  • memory loss, constant forgetfulness;
  • fatigue, especially after mental activity, general weakness;
  • sharp drops in blood pressure;
  • headache different nature and intensity;
  • dizziness, fainting;
  • nausea, vomiting;
  • blurred vision;
  • a bad dream;
  • the sensitivity of the violation;
  • mood swings, anxiety, nervousness, irritability.

If pathology becomes resistant nature,They talk about chronic brain ischemia. Its symptoms are more clear and deep: disturbed coordination of movements, they are uncertain and inhibited breathing frequent and shallow. Memory deteriorates even further, decreasing self-criticism, adaptation, enhanced emotional disorders. Further worsening walking, enuresis may be, mental disorders, growing into malfunction and the loss of opportunities to serve themselves.

brain ischemia and its diagnosis

In order to supply the patient with confidenceischemic diagnosis, it is subjected to a number of surveys, which results in the complex indicate the presence of disease. Patient figure out his life story and just the symptoms (history). As a rule, in patients with suspected cerebral ischemia are pathologies like ischemic heart disease, diabetes, hypertension, myocardial infarction, atherosclerosis, angina pectoris.

The doctor carefully examines the cardiovascular system:

  • It measures the pressure on both hands;
  • determines the pulse symmetry of the head and extremities;
  • It monitors the work of the heart and the abdominal aorta for rhythm disturbances.

Appointed by laboratory blood tests. From instrumental investigations may ECG, ECG, EEG, ultrasound, angiography, ophthalmoscopy, spondylography cervical spine MRI.

Ischemia of the brain - and the effects of treatment

Ischemia of the brain - and the effects of treatmentIf in time to see a doctor, noticingPrimary symptoms of the disease, the treatment turns out to be very productive. Basically, the brain ischemia involves conservative treatment, including taking medicines, aimed at strengthening the vascular walls and normalize blood flow. Sometimes, surgical intervention aimed at removing ateroskleroblyashki or thrombus, which is clogging the lumen of the vessel. If there is a chronic form of ischemic cerebral vascular drug therapy aimed at the suspension of the development of ischemia and prevention of ischemic stroke.

After improper treatment or transferredcerebral ischemia, the consequences can be very different: chronic encephalopathy, ischemic stroke, with all the possible complications (paralysis, speech disorders, motor skills, etc.) and death.
