A stroke is a type of cerebrovascular disease. “Cerebro” refers to the brain, and “vascular” means arteries and veins. A stroke occurs when blood vessels become narrowed or ruptured, disrupting the blood flow to the brain.

A brain stroke is a medical emergency for which treatment is intended as soon as possible. Although it may lead to disability, it is highly preventable.

Basically, it is the blood vessels in the brain that ruptures and bleeds, preventing blood and oxygen from reaching into the brain’s tissues. Without a continuous blood flow, the cells and tissues begin to die within a blink of an eye.
