Hemorrhagic stroke, or cerebrovascular accident, is a leading death as well as disability worldwide. Its prevention and early diagnosis are very important to avoid the consequences. Here we tell you some information that is interesting to know about them.
What is hemorrhagic stroke?
A stroke is the sudden stoppage of blood flow in an area of the brain. It can occur due to the blockage of a cerebral artery or vein, which would be called ischemic stroke, or by the rupture of a blood vessel.
It is this case of a ruptured vessel which is known as a hemorrhagic stroke. Hemorrhagic strokes are only 10-15% of all strokes that occur. The damaged vessel begins to bleed, producing a cerebral hemorrhage, and the territory after that rupture, which received blood and was nourished by that vessel, is left without irrigation.
That an area of the brain is left without irrigation causes all the cells that make up this tissue to begin to lack oxygen and lose the ability to function, eventually dying. In addition, the hemorrhage itself that forms compresses other brain areas, putting these cells at risk as well.
This is why, the longer an area passes without blood supply, the more serious the consequences will be. It is very important to know how to quickly recognize the symptoms that a stroke can cause in order to act accordingly and minimize the risk of sequelae.
Stroke is an emergency situation, before which the health services activate an action protocol. The aim is to diagnose and treat it as quickly as possible to avoid serious consequences, and even the death of the patient.
