MANY people know the word ‘stroke’, but perhaps only a few who understand it in depth, especially symptoms and risk factors. In fact, 80 percent of strokes were preventable.
Stroke or known in the medical designation Cerebrovascular Accident (CVA) occurs when a blood vessel in the brain suddenly blocked or ruptured. When this happens, the blood fails to flow to the brain area which is a supplier of oxygen and nutrients to the body.
As a result, brain and nerve cells will die and the ability of an area controlled by the brain is lost. Patients with stroke may be paralyzed, unable to speak, and in a coma – depending on where the stroke occurred and how many brain regions are damaged.
