Stroke, also known as cerebrovascular accident (CVA), is a condition wherein the blood flow to the brain is interrupted. When this happens, the brain is deprived of oxygen, leading to cell death and brain damage.Stroke is a severe impairment of brain functions due to acute brain circulation disorder. The highest percentage of strokes (80-85%) is due to thrombosis or embolism of the blood vessels, resulting in ischemia of the brain tissue. Approximately 10-15% of strokes are due to rupture of the blood vessel in the brain, with blood flowing into the brain, causing intracerebral, intraventricular or subarachnoid bleeding.
