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

## TL;DR

This paper updates a Chinese stroke recognition mnemonic to include more symptoms and emphasize quick action.

## Contribution

The paper introduces an enhanced version of the 'Stroke 1-2-0' mnemonic with added symptoms and repetition for better recall.

## Key findings

- Adding visual impairment and imbalance improves detection of posterior-circulation strokes.
- Repetition in the mnemonic may enhance recall and reinforce the need for immediate action.

## Abstract

“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.
