What is a Stroke or Brain Attack?
A stroke in the brain is damage to the brain from the interrupted blood supply. Poor blood flow to the brain results in the death of brain cells, and malfunctioning of the brain. This is also called a cerebrovascular accident (CVA). A stroke is a serious emergency that can lead to permanent neurological damage and even death.
The World Health Organization (WHO) says 15 million people worldwide are stroke victims each year. Among these, 5 million die and 5 million are permanently disabled.
WHO terms cerebrovascular accidents (stroke) as “the second leading cause of death and the third leading cause of disability in the world”.
High blood pressure is a leading cause, responsible for more than 12.7 million strokes worldwide. India reports about one million cases of brain stroke each year.
