What Really Happens in the Brain During a Stroke?

Introduction Every 40 seconds, someone experiences a stroke. But what actually happens inside the brain during those critical moments? Understanding the neurological changes during a stroke empowers you to take charge of your brain health before it's too late.

What Is a Stroke? A stroke occurs when blood flow to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Brain cells begin to die within minutes, making immediate medical attention vital.

Types of Stroke and Their Effects on the Brain

• Ischemic Stroke: Caused by a blockage in an artery supplying blood to the brain. It accounts for about 87% of all strokes.

• Hemorrhagic Stroke: Caused by a burst blood vessel leading to bleeding in the brain.

• Transient Ischemic Attack (TIA): A "mini-stroke" that lasts a few minutes but serves as a warning sign.

Each type affects the brain differently but can result in long-term damage depending on the area impacted.

Why “Time is Brain” The longer a stroke goes untreated, the more brain tissue is lost. Every second counts—millions of neurons die every minute during a stroke.

How the Brain Tries to Protect Itself The brain uses surrounding pathways to reroute functions when one part is damaged. This neuroplasticity is your brain's natural recovery mechanism—but it needs support.
