📖What is Ischaemic Stroke?
Ischaemic stroke is the most common type of stroke, occurring when a blood clot or other obstruction blocks blood flow to part of the brain, depriving brain tissue of oxygen and nutrients. Without prompt restoration of blood flow, the affected brain cells begin to die within minutes, making rapid recognition and treatment critical to minimising permanent damage, a principle often summarised as "time is brain." The blockage can result from a clot that forms directly within a narrowed brain artery, or from a clot that forms elsewhere in the body, often the heart, and travels to lodge in a brain artery. The specific symptoms and their severity depend on which part of the brain is affected and how much tissue is damaged before blood flow is restored. Emergency treatment within a critical time window can significantly limit brain damage and improve recovery, making immediate medical attention for any sudden stroke symptoms essential.
