Key Takeaways
- Research suggests playing mahjong is linked to better cognitive scores and stronger executive function in older adults.
- A 10-year study of over 7,000 older adults in China showed that mahjong players maintained or improved their cognitive scores, while non-players experienced declines.
- A 12-week trial demonstrated that regular play helped adults with mild cognitive impairment improve their ability to handle everyday tasks like cooking and managing finances.
What the Source Says
Mahjong originated near Shanghai, China, in the mid- to late-1800s and was eventually brought to the United States. It is a strategic tile game played by four people around a square table using a set of 136 to 152 tiles. Players draw, discard, and collect tiles across rounds, requiring them to memorize played pieces, anticipate opponents' moves, and make rapid strategic adjustments.
The game is experiencing a major surge in interest, with Yelp reporting a 4,467% year-over-year increase in searches for mahjong clubs. Beyond its social appeal, studies suggest it offers measurable cognitive benefits. Research tracking over 7,000 older adults over ten years revealed that mahjong players consistently performed better on cognitive assessments than non-players. Playing more frequently was directly linked to improved attention, memory, reaction time, and task coordination.
In another randomized controlled trial, older adults diagnosed with mild cognitive impairment (MCI) played mahjong three times weekly for 12 weeks. Compared to a control group, the players showed noticeable improvements in executive function—the mental skills used for planning and decision-making—and performed better in practical daily tasks such as transportation, cooking, and managing personal finances.
Practical Notes
Unlike conventional mental exercises that can feel repetitive, mahjong naturally exercises multiple brain domains at once through memory, dynamic strategy, and real-time social interaction. Because it is enjoyable and accessible, players are more likely to stick with it over time.
Adults interested in learning can look for local play groups hosted at senior centers, community facilities, or libraries, or review beginner instruction videos online.
