Simply put, a stroke is when your brain does not get any blood. Professionally put, a stroke is a rapid onset of cerebral deficit due to poor vascular supply to a part of, or the complete brain tissue, leading to loss of consciousness, and as an extension, death.

Your brain requires oxygen to function. And when the required levels are not met, cell death or apoptosis and tissue death or necrosis happens. This results in damage to your nerve cells, which spreads rapidly and affected the whole body’s function. There are different types of strokes based on their etiology or cause.
