Which symptom is commonly associated with an acute stroke?

• A. Sudden onset unilateral weakness
• B. Chronic headaches over months
• C. Gradual memory decline
• D. Rash

Answer: (A)

Acute stroke causes an abrupt loss of blood flow to part of the brain, producing a sudden, focal neurologic deficit that is maximal at onset. The most typical sign is sudden weakness on one side of the body, reflecting involvement of motor pathways in one hemisphere and resulting in contralateral weakness. This presentation is immediate rather than progressive, which helps distinguish it from other issues. The other options point to conditions that are not strokes—like chronic headaches, gradual memory decline, or a rash. Recognizing sudden unilateral weakness as a stroke symptom underscores the need for urgent evaluation and imaging.
