Which of the following is NOT a sign of a stroke?

In the context of a stroke, signs and symptoms typically include a range of neurological deficits, such as loss of speech, cognitive dysfunction, and changes in alertness. Each of these indicates a disruption in brain function often associated with a stroke, which occurs when the blood supply to part of the brain is interrupted or reduced.

Loss of speech, or aphasia, happens when areas of the brain responsible for language are affected. Cognitive dysfunction can manifest as confusion, memory issues, or difficulty with problem-solving, which are common when the brain is damaged. Changes in alertness, such as increased drowsiness or confusion, often accompany neurological events like strokes.

In contrast, increased energy is not associated with a stroke. This symptom does not correlate with the physiological impacts of a stroke, which typically leads to fatigue, weakness, and reduced physical capability due to the immediate effects on brain function and overall health. Understanding these distinctions is crucial for recognizing the symptoms of a stroke and responding appropriately.
