Cerebrovascular diseases

Cerebrovascular diseases, even called as diseases that affect brain vessels, stroke (cerebral embolism, brain thrombosis, cerebral bleeding, cerebral infarction) mainly develop in the form of sudden onset symptoms.

In the background usually we find an internal medicinal disease, for example high blood pressure, diabetes, high cholesterol level, heart disease, congenital or acquired susceptibility for thrombosis or smoking.

There can be two types of cerebrovascular traumas: cerebral bleeding or cerebral infarction, which develops as a result of vascular obstruction. The incidence of cerebral infarction is five times higher, and it is often preceded by temporary (usually couple of minute long) malaise with transient neurological symptoms. In such cases with aimed medical check-up the cause can usually be discovered and the stroke of apoplexy, which has permanent effects, can be prevented.


Stroke occurs with sudden onset symptoms (without listing all symptoms):

  • Unilateral numbness or numbness affecting only one limb, weakness, paralysis
  • Clumsy limbs, imbalance, whirling dizziness, double vision
  • Disorder of processing speech and expressing oneself
  • Unilateral blindness or scotoma
  • Confused mind, loss of consciousness, in most severe cases coma, cardiac/respiratory arrest

Stroke or its anticipating temporary neurological symptoms require urgent institutional examination and care anyway.

In case of chronic cerebrovascular diseases, estimation of the functional reserve capacity may help to decide about the necessity of the cerebrovascular surgical intervention.
