WHAT IS A STROKE? When the blood supply to the brain is disturbed in some way and brain cells are starved of oxygen causing some cells to die and leaving other cells damaged or dead it's call a stroke.
Most strokes happen when a blood clot blocks one of the arteries (blood vessels) that carry blood to the brain. Brain cells are starved of oxygen causing some cells to die and leaving other cells damaged when the blood supply to the brain was disturbed in some way. This type of stroke is called an ischemic muscular atrophy stroke.
STROKE- Transient is chemic attack (TIA) is a short-term stroke that lasts for less than 24 hours. The oxygen supply to the brain is restored quickly, and symptoms of the stroke disappear completely. A transient stroke needs prompt Medicine attention as it is a warning of serious risk of a major stroke.
