The Science Behind a Stroke: What Happens to Your Brain and How to Stay Safe

Understanding Stroke: What Is It?

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. Because of this, quick action is very important. Strokes can cause lasting brain damage, disability, or even death. According to the CDC, stroke is a leading cause of death and disability worldwide.

What Happens in the Brain During a Stroke?

During a stroke, the brain does not get enough oxygen and nutrients. As a result, brain cells begin to die. 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 occurs when a blood vessel in the brain bursts, causing bleeding.

In both cases, parts of the brain cannot work as they should. Therefore, the body may lose certain functions, like speech or movement.

Common Symptoms and Warning Signs of Stroke

Recognizing stroke symptoms early can save lives. If you notice any of these signs, act fast:

Sudden numbness or weakness in the face, arm, or leg, especially on one side

Sudden confusion or trouble speaking

Sudden trouble seeing in one or both eyes

Sudden trouble walking, dizziness, or loss of balance

Sudden severe headache with no known cause

Remember the word FAST to spot stroke signs:

Face drooping

Arm weakness

Time to call emergency services

Main Causes and Risk Factors

Several things can raise your risk of stroke. Some you can control, while others you cannot. However, knowing your risks can help you take action.

High blood pressure

Diabetes

Diagnosis and Immediate Actions

If you think someone is having a stroke, call emergency services right away. Quick treatment can save lives and reduce long-term damage. Doctors use tests like brain scans (CT or MRI) to find out what type of stroke is happening. Early treatment may include medicine to break up clots or stop bleeding. Therefore, do not wait if you see warning signs.
