TED-ED: What happens during a stroke? - Vaibhav Goswami

Strokes are a leading cause of death and disability, requiring quick medical intervention. The brain, though small, needs a significant amount of oxygen, supplied by arteries. Strokes occur when blood flow is interrupted, either by a hemorrhage or a clot, leading to brain cell death. Symptoms vary based on the affected brain area, and immediate treatment is crucial. Treatments include medication and procedures like thrombectomy. The FAST test helps identify strokes quickly, emphasizing the need for urgent medical care.
