Detailed explanation-1: -Stroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage, leading to the more common ischemic stroke, or by bleeding in the brain, leading to the more deadly hemorrhagic stroke.

Detailed explanation-2: -Ischemic stroke occurs when a blood vessel that supplies blood to the brain is blocked by a blood clot. This may happen in two ways: A clot may form in an artery that is already very narrow. This is called a thrombotic stroke.

Detailed explanation-3: -A stroke is a life-threatening condition that happens when part of your brain doesn’t have enough blood flow. This most commonly happens because of a blocked artery or bleeding in your brain. Without a steady supply of blood, the brain cells in that area start to die from a lack of oxygen.

Detailed explanation-4: -Types of stroke: Ischaemic strokes happen when an artery supplying blood to your brain is blocked by a blood clot. Haemorrhagic strokes happen when a blood vessel ruptures (or bursts), causing a bleed in the brain. This means less blood gets to the surrounding brain cells causing them to die.
