Mahjong "a viable treatment option" for dementia

Researchers in Hong Kong who examined the effect of mahjong on the
cognitive functioning of elderly individuals with dementia say it is a
viable treatment option requiring no professional supervision and
entailing minimal or no cost to an institution.
Earlier research has suggested that increased participation in cognitive
activities is associated with a lower risk of development of dementia.
One recent study of older people in China found that those who regularly
engaged in mentally stimulating activities such as playing board games
and reading had a reduced risk of cognitive impairment, while their
peers who spent more time watching television had an increased risk.

In a new exploratory study, researchers from the Department of Applied
Social Studies at the City University of Hong Kong set out to explore
the effect of mahjong on the cognitive functioning of 62 people with
mild to moderate dementia. Mahjong is a traditional Chinese board game
that involves cognitive domains such as attention, memory, calculation
and planning.

Mean age of the participants was 83.9 and all had an initial Mini-Mental
State Examination (MMSE) score of 24 or lower. The participants were
able to play mahjong, but had not played for the past six months. They
were randomly assigned to play either twice (n = 33) or four times (n =
29) a week over a 16-week duration. Digit forward span, digit forward
sequence, verbal memory and MMSE score were measured at baseline,
post-test and at one-month follow-up.

The results showed that, regardless of frequency of playing, mahjong
produced consistent gains across all cognitive performance measures. It
had large effect sizes on digit forward memory (1.0-1.4 for both span
and sequence), moderate-to-large effect sizes on verbal memory
(0.5-0.9), and a moderate effect size on MMSE (around 0.6). Moreover,
said the investigators, the effects lasted after mahjong had been
withdrawn for a month, "suggesting that constant practice is not
necessary to achieve therapeutic effect once an initial threshold is
attained".

The team concluded that mahjong is a viable treatment option for
dementia. They added, "Because mahjong therapy basically does not
require professional supervision and can be implemented as widely as
space allows at a given time, the potential benefits of integrating
mahjong into the daily routines of an institution are enormous vis--vis
minimal, if any, cost to the institution."

Note that no difference was found between the randomized groups...

Any statistician would conclude there was no evidence for an effect.

Ah Jim... You know I have been spending about 20 minutes a day on
this for about a year. My time to completion went from 10 minutes to 5.
I guess practice makes perfect but it was a good feeling to see mastery
for someone who could not remember if he put sugar in his coffee and had
(not sure of that tense) to look to make sure. Wink) I think that statin
folks with cognitive concerns still may want a look see.

Alas just one data point.

I'd add that Mahjong is challenging and not passive yet fun at the same
time. Not bad if it works for some folks.

I have been playing chess since my childhood. Do you think that mahjong is
more challenging for brain than chess?

Not a mahjong or chess expert. I just can say that the myriad visual
stimuli options with a time factor is challenging in mahjong. No one
to improve but oneself. Worth a gander. Folks with cognitive problems
may benefit. I believe you can find a combative option if so inclined.
I try to beat my self and have been rather good at this. You know
far before told no. Wink) Like muscle pain etc...


Chess is to Go
as Mahjong is to kung fu aka hard work.

Done alone with determination like trying to give up a walker.
Only not seen by anyone.

Health is mystery yet I want to ride or surf what comes along well.

Best!

Sorry, but a "no difference" between a dementia patient and a control where
memory is concerned is a major leap forward for the dementia patient.

The expectation is that there WOULD be a difference.

I wonder if playing Mahjong on-line would count?

I don't see why not as the visual, mental and dimensional aspects are

present and still challenging. Coordination of these attributes I
believe is what may be healing.

There was random assignment of the cog. impaired subjects
to the two groups. The is no mention of any normal control group.
That is pure fiction by Sharon Hope.

The two groups did different (non-zero) amounts of mahjong play.


Quote:

No, the expection would be that different amounts of mahjong
would vary the amount of effect from mahjong. The variation
estimates the effect from mahjong. That effect is not significant.

Only things which did not vary between the two groups would be
good candidates to guess as an explanation for the benefit observed.
The reference to TV time in the story was also a bad explanation
since reducing TV time twice as much did not give increased
benefit.

Jim Chinnis is correct that there was no evidence for an effect.
