Stroke | What Causes A

In the complex network of the human body, the brain is the command center, requiring a constant flow of oxygen and nutrients to function. A stroke is essentially a "brain attack" that happens when this vital supply line is suddenly severed or compromised. To understand why this happens, we can look at the two primary ways these biological pipelines fail. The Blockage: Ischemic Stroke

A clot forms elsewhere in the body—often in the heart due to an irregular rhythm like Atrial Fibrillation (AFib) —and travels through the bloodstream. It eventually reaches a vessel in the brain that is too narrow for it to pass through, causing an immediate blockage. The Break: Hemorrhagic Stroke what causes a stroke

About 87% of all strokes are . In this scenario, a blood vessel becomes obstructed, preventing blood from reaching brain cells, which then begin to die within minutes. This blockage usually occurs in one of two ways: In the complex network of the human body,

Over many years, fatty deposits called plaque (made of cholesterol and calcium) build up on the inner walls of the arteries. This narrows the "pipes" until a blood clot forms at the site, completely sealing off the vessel. The Blockage: Ischemic Stroke A clot forms elsewhere
