Games to help cognitive decline
Should you prescribe Wordle?

- Research suggests that digital and analog games may ward off cognitive decline, which can be common during aging.
- Games may prove useful for clinicians who promote healthy aging among their patients, as the global population over the age of 60 is projected to increase to 2.1 billion by 2050.
- Computerized games designed explicitly for cognitive enhancement, as well as traditional analog games and physical-video hybrids, have all demonstrated mental—and in some cases, physical—efficacy.
Take a moment to look at the patients in your waiting room. Many are likely locked on to their smartphones, and some may be among the millions playing Wordle, a puzzle that gives players six chances to guess a five-letter word.
The rise of Wordle got the attention of The New York Times, which added the game to its suite of brainteasers for a sum estimated in the low seven figures. A game with a massive following has monetary value, but do games like this also have clinical utility?
Promising research on cognitive games
The world’s population increasingly has a touch of gray, according to the WHO. Globally, there were 1 billion people over the age of 60 in 2019. The WHO estimates that there will be 1.4 billion in this age category by 2030 and 2.1 billion by 2050. Efforts to stave off cognitive decline may prove essential for this aging population.
Cognitive games are one way to do it. A 2020 meta-analysis published in Scientific Reports offers some insights.
Researchers reviewed 16 studies comprising more than 1,500 participants to examine whether computer-based games could improve various cognitive measures among a group of people over the age of 60 without cognitive impairments.
Among the findings were statistically significant improvements in processing speed, working memory, executive function, and verbal memory. There was no relationship between the participant’s age and the amount of training required. This suggests that healthy older adults retain the ability to learn as they age.
For clinicians, the researchers suggested including commercial computerized cognitive games among their recommendations to older patients to help them avoid cognitive decline and maintain cognitive abilities. Such games should be used in combination with healthy lifestyle, aerobic exercise, and other methods of brain training, the researchers wrote.
The games assessed in this study were, for the most part, developed explicitly to improve cognitive performance. This is not the case with Wordle. However, other research indicates that more conventional games—and even some classics—have their clinical benefits.Related: The surprising health benefits of this ‘lazy’ pastime
What about board games?
How about a game of chess, bingo, cards, or a crossword puzzle? If your patients aren’t tech-savvy, a 2019 longitudinal cohort study published in The Journals of Gerontology suggests that games of the old school, analog variety are associated with less relative cognitive decline.
This study Included 1,091 people living in Scotland. All were born in 1936 and were living independently in their communities throughout the study. Cognitive function was assessed at age checkpoints starting from age 11 up to age 79, using 14 cognitive tests. The assessments at age 11 served as controls. Later in life, at ages 70 and 76, researchers asked the participants if they were still playing analog games.
Those who gamed more frequently tended to exhibit the following:
– At age 70, elevated cognitive function, the majority of which could not be attributed to control variables.
– From age 70 to 79, less general cognitive decline and less memory decline.
– From age 70 to 76, less of a drop in cognitive speed among those who increased their gaming
The researchers note that, for clinicians, the difficulty lies in the application of these findings. “It will be a challenge to determine how best to apply these findings in practice, as our results suggest that a lifetime of playing games is the best way to capture the benefits,” the researchers wrote.
Acknowledging that evidence is still limited, the researches stated that “there do not appear to be any harmful effects of playing games. Thus, analog games are an affordable and fun activity that could protect against cognitive decline.”
Digital games, real-world benefits
While analog games are helpful, research indicates that asking aging patients to pick up a game console controller may be beneficial for them, too.
A 2020 systematic review published in Games for Health Journal combed five databases to identify articles that could shed light on whether video games promoted physical and mental health among people age 65 and older. Of the 806 articles they found on this topic, 23 met their inclusion criteria.
Among those 23 studies, 20 demonstrated that video games improved physical health, and 14 showed that they promoted mental health.
For physical health, researchers found that video-game interventions improved walking/gait, fitness, strength, mobility, and balance.
Mental-health benefits included better processing speed, executive function, reaction time, and confidence in one’s balance. The most popular intervention was Exergame, a platform that blends physical exercise with digital interfaces, emulating a videogame experience.
The researchers concluded that additional research may firm up a surprising hypothesis:
“We also found that videogame-based interventions could outperform traditional training programs regarding walking performance/gait parameter, balance confidence/fear of falling, and executive functions. However, our review could not find any articles that reported direct social health outcomes.”
What this means for you
Cognitive games may help stave off cognitive declines among an increasingly older population.While the increasingly popular game Wordle hasn’t been studied directly yet for any cognitive benefits, research indicates that digital games are, in fact, effective and that similar benefits can be obtained from traditional analog games. Based on these findings, clinicians can regard games as a useful tool to support healthy aging.
