Question: 1 / 400

What is a common sign of a stroke?

Severe headache

Sudden weakness on one side of the body

Sudden weakness on one side of the body is a hallmark sign of a stroke, particularly in the case of ischemic strokes, which occur when blood flow to a part of the brain is blocked. The brain relies on a continuous supply of blood to function correctly, and when this blood supply is disrupted, it can lead to the loss of function in the areas of the body controlled by the affected part of the brain. This is usually characterized as weakness or paralysis on one side, also known as hemiparesis. Recognizing this sign quickly is crucial, as timely medical intervention can significantly improve the outcome for the patient.

Other signs of stroke can include facial drooping, difficulty speaking, and sudden vision changes, but sudden weakness on one side is often the most noticeable and alarming to witnesses, prompting them to seek immediate medical help.
