A stroke or brain attack is a condition in which the brain cells suddenly die due to a lack of oxygen. It can be caused by an obstruction in the blood flow or the rupture of an artery that feeds the brain. The patient may suddenly lose the ability to speak, there may be memory problems, or one side of the body can become paralysed.
Brain stroke is the second common cause of death and the fourth leading cause of disability worldwide. Approximately 20 million people each year suffer from stroke, 5 million of whom do not survive. In India, it is a leading cause of death and disability in the young population.
