Which of the following is a common sign of a stroke?

A common sign of a stroke is loss of balance or coordination. This symptom occurs because a stroke can impair the brain's ability to control movement and spatial orientation. The affected areas of the brain may struggle to communicate with other parts of the body, leading to difficulties in maintaining balance, coordination of limbs, and overall motor function. Recognizing this symptom is crucial, as it can indicate that the brain is not getting enough blood flow, requiring immediate medical attention.

In contrast, increased appetite, rapid heart rate, and excessive sweating are not typically associated with stroke and may indicate other medical issues or conditions. Understanding the signs of a stroke, like loss of balance or coordination, can help individuals act quickly and seek emergency medical care, which can be vital for improving outcomes.
