10 Little-Known Stroke Varieties and Their Hidden Dangers

10. Global Ischemic Stroke: A Brain-Wide Crisis

Unlike a localized blockage, a global ischemic stroke (also known as hypoxic-ischemic encephalopathy) occurs when the entire brain suffers from insufficient blood flow and oxygen. This typically results from a major event like cardiac arrest, severe shock, or profound drops in blood pressure, leading to widespread brain cell damage rather than a focal lesion. The effects can be devastating, ranging from coma and severe cognitive impairment to persistent vegetative states. Understanding this type highlights the critical importance of rapid cardiopulmonary resuscitation (CPR) and maintaining stable vital signs during medical emergencies to prevent widespread brain injury.
