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

A common sign of a stroke includes sudden confusion and trouble speaking. This occurs because a stroke impacts the areas of the brain responsible for processing language and communication. The brain cells begin to die due to a lack of oxygen supply, leading to changes in cognitive function and difficulties in forming words or understanding language. Recognizing these signs is crucial, as immediate medical intervention can significantly affect the outcome for someone experiencing a stroke.

The other options—persistent cough, chest pain, and fever with chills—are not indicative of a stroke but may point to other medical conditions. These symptoms relate more closely to respiratory issues, cardiovascular issues, or infections respectively, emphasizing the importance of recognizing the specific symptoms associated with a stroke for timely treatment.
