What causes Stroke?

by Dr. Santhosh N U

Dr. Santhosh N U Consultant - Neuro Surgery and Endovascular Neuro Surgery briefs about Stroke. A stroke occurs when a blockage or bleed of the blood vessels either interrupts or reduces the supply of blood to the brain. When this happens the brain does not receive enough oxygen or nutrients & brain cells start to die. This is a medical emergency. Although many strokes are treatable some can lead to disability or death.
