What Is a Stroke?

A stroke is a medical emergency. It happens when blood flow to part of the brain stops. Without blood, brain cells start to die within minutes. There are two main types of stroke:

Ischemic stroke: This is the most common type. It happens when a blood clot blocks a blood vessel in the brain.

Hemorrhagic stroke: This type happens when a blood vessel in the brain bursts and bleeds.

Both types can cause serious brain damage. However, quick treatment can save lives and reduce harm.

What Happens in the Brain During a Stroke?

During a stroke, part of the brain does not get enough oxygen. As a result, brain cells in that area begin to die. This can affect how you move, speak, or think. Sometimes, the damage is mild. Other times, it can be severe or even life-threatening. Because the brain controls the body, a stroke can change many things at once.

How Are Strokes Diagnosed?

Doctors use several tests to diagnose a stroke. First, they check your symptoms and medical history. Next, they may order brain scans, such as a CT or MRI. These tests show if there is bleeding or a blocked vessel. Blood tests and heart tests can also help find the cause. Quick diagnosis is key for the best treatment.
