Understanding Stroke Mechanisms and the Importance of Timely Treatment

A stroke occurs when blood flow to the brain is cut off or blood vessels rupture, causing rapid oxygen starvation and neuronal tissue damage within minutes.

Medical interventions such as intravenous thrombolysis can be administered within 4.5 hours for ischemic strokes, while mechanical thrombectomy can remove clots up to 24 hours later.

For hemorrhagic strokes, treatment strategies involve blood pressure control, intracranial pressure management, and surgical procedures where necessary.
