Why is timely intervention critical in the case of an ischemic stroke?

Timely intervention in the case of an ischemic stroke is critical primarily because it aims to restore blood flow quickly to the affected brain tissue. Ischemic strokes occur when a blood vessel supplying blood to the brain becomes blocked, usually by a blood clot. This blockage leads to a lack of oxygen and nutrients in the brain tissue, which can rapidly result in cell death and long-term disability if left untreated.

Restoring blood flow as quickly as possible minimizes the extent of brain injury and increases the likelihood of a favorable recovery. Treatments such as thrombolytic therapy (clot-busting drugs) or mechanical thrombectomy are most effective when administered within a specific time frame from the onset of symptoms. The faster blood flow is restored, the better the chance of salvaging brain tissue and enhancing the overall outcomes for the patient.
