Which of the following is a sign of a stroke?

Slurred speech and sudden dizziness are both recognized signs of a stroke. When a person experiences a stroke, their brain is deprived of oxygen, which can lead to various neurological symptoms. Slurred speech occurs because the brain may struggle to coordinate the muscles needed for speaking, indicating an impairment in the areas responsible for language and motor functions. Sudden dizziness can be a result of disruption in the brain's blood supply that affects balance and coordination, drawing attention to potential issues related to the body's ability to maintain stability.

Both slurred speech and sudden dizziness are part of the acronym FAST, which stands for Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services. This acronym helps people recognize the signs of a stroke quickly and act promptly. Recognizing these signs is critical, as immediate medical attention can significantly improve outcomes for stroke patients. Frequent coughing, while it might indicate other health issues, is not typically associated with stroke symptoms and does not fit within the framework of sudden neurological changes typically observed during such an event.
