That majong is good for us is music to our ears (well, at least for some of us who actually play majong). The claim is based on recent research findings, which has led to reports that “tai chi, majong offer hope for dementia patients” (South China Morning Post, 22 April 2013; see also a similar report in www.majongnews.com).
The evidence is based on two studies. The first showed that a 3-times-a-week programme of either tai chi or majong for 12 weeks was significantly more effective in reducing depression scores among older adults with mild dementia and moderate depression in nursing homes than a handicraft control condition (Cheng et al., 2011). The second showed that the same programme was effective in improving cognitive task performance for a sample of 110 participants with the same population characteristics (Cheng et al., 2012); the first study sampled 12 participants for each condition. It’s not the case that the findings are limited to only nursing residents because these results replicate an earlier finding by Cheng and colleagues. Their 2006 study found that playing majong twice or four times a week for a duration of 16 weeks improved the cognitive performance of 62 older adults living in the community.
Although it would appear that playing majong is helpful in protecting against dementia, it would be wise to also observe that the participants in the 2006 study had not played (although they knew how to play) the game for at least 6 months prior to the study. Similarly, nursing residents were also not regularly practising tai chi or playing majong on a regular basis before the intervention programme was implemented. That is to say, there may be some benefit initially of engaging in mentally challenging activities, but at some point the cognitive demand of these activities may not be sustained over the longer term.
So the advice is to provide your brain with opportunities to grow new neural connections. Giving yourself cognitively demanding tasks like mastering a new language, musical instrument, skill, dance, game, or exercise form, serves this purpose. Learning to play a mentally challenging game like Chinese or international chess, weiqi, taboo, scattergories, and majong for the first time will definitely put us out of our comfort zone. But with a little practice (or a lot for strategy games), it likely loses its edge in its ability to build cognitive reserves and its protective cloak against Alzheimer’s disease. If you’re feeling comfortable, whatever you’re doing is not likely to be of extra benefit. If you’re feeling the strain on your brain, you should keep doing it (at least for a while).
Learning is important. But what’s crucial is that we keep levelling up.
