Stroke

Stroke is a significant health problem globally. It is the third leading cause of death in Malaysia. A stroke happens when the supply of blood to the brain is suddenly disrupted.

Blood is carried to the brain by blood vessels called arteries. When a stroke happens, blood may stop moving through the artery either because the artery is blocked by a clot or plaque, or because the artery breaks or burst. When blood stops flowing, the brain does not get the oxygen it needs, causing brain cells in the blocked area to die, which may lead to permanent brain damage.

Some strokes are fatal, while others cause permanent or temporary disability. It is important to understand that stroke can be prevented.
