A stroke is an acute disturbance of blood flow to the brain that suddenly deprives part of the brain of its blood supply. Worldwide, it is the second leading cause of death and the leading cause of disability among adults. In Ukraine, about 128,000 strokes are recorded every year. According to the World Stroke Organization (WSO<\/a>), nearly 12 million new strokes occur worldwide each year, and one in four adults over the age of 25 will have a stroke during their lifetime. About 60% of patients are left with some degree of disability, and only up to 25% return to full working capacity. It is a medical emergency: every minute counts.<\/p>\n

What Is a Stroke, and Why Is It Dangerous?<\/h2>\n

The brain is supplied with oxygen and glucose through a network of blood vessels. When that blood supply is interrupted, neurons begin to die within minutes. Research <\/a>shows that during a stroke, the brain loses roughly 1.9 million neurons every minute. Without rapid restoration of blood flow, irreversible cell death occurs in the affected area.<\/p>\n

At the center of the damage, an ischemic core forms \u2014 the area of most severe and irreversible tissue injury. Around it lies the penumbra, tissue with reduced blood flow that may remain viable if circulation is restored in time. This is the tissue that may still be salvaged when blood flow is restored promptly \u2014 which is why emergency stroke care is measured not in hours, but in minutes.<\/p>\n

Types of Stroke: Ischemic and Hemorrhagic<\/h2>\n

There are two main types of stroke. Ischemic stroke is caused by a blood clot blocking a vessel and is by far the more common type. Hemorrhagic stroke occurs when a blood vessel ruptures and bleeds into brain tissue; it is less common but carries a higher mortality rate.<\/p>\n

Ischemic Stroke<\/h3>\n

Ischemic stroke accounts for about 85% of all cases. A blood vessel is blocked by a thrombus \u2014 a blood clot \u2014 or, in some cases, by material from an atherosclerotic plaque. Deprived of oxygen, the affected area of the brain can begin to sustain irreversible damage within minutes.<\/p>\n

Hemorrhagic Stroke<\/h3>\n

Hemorrhagic stroke occurs when a blood vessel ruptures and bleeds into brain tissue, increasing pressure inside the skull. Mortality from hemorrhagic stroke is roughly twice as high as that from ischemic stroke, even when the affected area is smaller.<\/p>\n

Early Signs of Stroke: How to Recognize Them in One Minute<\/h2>\n

Stroke symptoms appear suddenly. To quickly check for signs of a suspected stroke, the FAST acronym is widely used:<\/p>\n
