Updating “Stroke 1‐2‐0” by Extending Recognition to Posterior‐Circulation Stroke and Reinforcing Rapid Action in China

“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.
