A sudden headache, dizziness, or trouble speaking can be frightening. A stroke happens when blood flow to the brain is blocked, causing damage that can manifest in different ways. Some strokes are mild, while others can quickly become life-threatening. Understanding the risks, causes, and warning signs can help. This self-assessment quiz will guide you through the signs and symptoms of when you should seek medical help.

What Causes a Stroke?

A stroke occurs when the brain doesn't get enough blood. This can happen due to a clot blocking a blood vessel (ischemic stroke) or a blood vessel bursting (hemorrhagic stroke). High blood pressure, smoking, and diabetes can increase the risk.

Can a Stroke Get Worse?

Some strokes cause mild symptoms that improve, while others can get worse quickly. Without fast treatment, brain cells begin to die, which can lead to lasting damage and potentially fatal consequences. Recovery depends on the type of stroke and how quickly it is treated.

How Common Are Strokes?

Strokes are a leading cause of disability worldwide. While they can occur at any age, the likelihood of these events significantly rises in individuals over the age of 50. Many strokes could be prevented with lifestyle changes and managing health conditions like high blood pressure.

When Should You Be Concerned?

Sudden weakness, numbness on one side of the body, trouble speaking, or vision changes could be emergency signs of a stroke. Symptoms can happen suddenly or build up over time. Recognizing early warning signs can help improve your chances of recovery.
