"Stroke 1-2-0" is a Chinese numeric mnemonic linking face drooping, arm weakness, and speech difficulty to calling emergency services (1-2-0). We propose an enhanced repeated version-"Stroke 1-2-0, Stroke 1-2-0"-that adds visual impairment and imbalance to better detect posterior-circulation strokes, while repetition may boost recall and stresses zero delay in seeking help.
