Pilot Randomized Controlled Trial of the GO Game Intervention on Cognitive Function

Effects of game-based digital interventions for mental disorders: A meta-analysis

With increasing research attention on game-based digital interventions for mental disorders, a number of studies have been conducted to explore the effectiveness of digital game-based interventions on mental disorders. However, findings from previous research were inconsistent. Thus, we conducted a comprehensive meta-analytic review of the effectiveness of game-based digital interventions for mental disorders. By searching the articles in databases, we identified 53 studies in which 2433 participants were involved, and 282 effect sizes were extracted. Among the 53 studies, 14 employed within-group (pre/post) designs, and the remaining 39 utilized controlled trial designs. Using a three-level random-effects meta-analytic model, a medium effect size of game-based digital interventions (g = 0.47, 95 % CI: 0.33, 0.61) was revealed in the controlled trial designs and a close-to-medium effect size (g = 0.45, 95 % CI: 0.32, 0.58) was found in the within-group (pre/post) designs, indicating close-to-medium-sized efficacy of game-based digital interventions for mental disorders. Moderator analyses showed that age in the controlled trial designs had contributed to the heterogeneity in previous studies, suggesting that interventions might be more effective for the elderly. However, given that only a limited number of studies were focused on the elderly, more studies with older participants should be conducted in the future to provide more robust evidence and explore the mechanisms of how digital gaming interventions can be more effective in improving mental disorders symptoms.

"GO" to move toward dementia-friendly communities: A pilot study

BACKGROUND

To the creation of mutual aid relationships among people with cognitive decline is important in aging societies. This study aimed to develop and examine the feasibility of a GO Program in which older adults, with experience in playing GO, support the learning of GO by older adults with cognitive decline and other barriers to social participation, which in turn reduces social isolation and creates opportunities for older adults to use their role.

METHODS

This single-arm intervention study was conducted in Tokyo, Japan. Introductory GO classes were held for 10 participants who had never played GO (beginners) and 10 participants who had (supporters) once a week for an hour, for a total of 12 sessions. Supporters and beginners were paired to solve problems and play games. We assessed the feasibility of the program and its effects on mental health social network, and cognitive function.

RESULTS

Cognitive test scores were at the mild cognitive Impairment level for beginners as well as for supporters. Satisfaction with the program was high, with an overall class attendance rate of 99.1% and none leaving the program. No significant changes were observed over time for beginners in each measurement; however, there was a significant improvement in the Mini Mental State Examination-Japanese scores for supporters (p < .05).

CONCLUSIONS

The results suggest that this program could contribute to the creation of mutual aid relationships among older adults with cognitive decline; even if they have mildly declined cognitive function, they can still play an active role in society. Moreover, creating such opportunities may positively impact cognitive function.

GO Revisited: Qualitative Analysis of the Motivating Factors to Start and Continue Playing GO

PURPOSE

To explore the motivating factors for starting and continuing to play GO among older adults, as well as to examine the effect of GO activities in helping people to live well with, as well as to prevent, dementia.

DESIGN

Qualitative descriptive research.

METHODS

Semi-structured interviews were conducted.

FINDINGS

The participants reportedly started playing GO for dementia prevention, and to cope with their anxieties about aging. They described feeling relaxed while playing GO. They also felt that playing GO fostered human relationships.

CONCLUSIONS

GO is effective in assisting older adults to cope with aging issues, cultivate peace of mind and encourage interaction with peers.

CLINICAL EVIDENCE

GO is effective in assisting older adults to cope with aging issues, cultivate peace of mind and encourage interaction with peers.

Can Traditional Board Games Prevent or Slow Down Cognitive Impairment? A Systematic Review and Meta-Analysis

BACKGROUND

Traditional board games can entail significant skills encompassing several cognitive functions across different domains. Therefore, they may potentially represent effective cognitive interventions in the aging population with or without Alzheimer's disease or other types of dementia.

OBJECTIVE

We aimed at verifying the hypothesis that traditional board games can prevent or slow down cognitive decline, through a systematic review on traditional board games and dementia.

METHODS

We searched five databases with tailored search strings. We included studies assessing the impact of board games on elderly subjects at risk of or suffering from cognitive impairment, or subjects with cognitive impairment irrespective of age. Studies where the effect of board games was not separated by cards or other games were excluded. A meta-analysis was performed for specific cognitive and non-cognitive outcomes.

RESULTS

Board games improved mental function, as measured by Montreal Cognitive Assessment (p = 0.003) and Mini-Mental State Examination (p = 0.02). Ska and Go improved Trail Making Test -A, while Mahjong improved executive functions. There was no consistent effect across different games on Digit Span or Categorical Fluency. Chess improved quality of life measured with the WHO-QoL-OLD scale (p < 0.00001). Mahjong temporarily improved depressive symptoms. Go increased BDNF levels and left middle temporal gyrus and bilateral putamen metabolism.

CONCLUSIONS

Traditional board games may slow global cognitive decline and improve the quality of life in elderly subjects. Different games have varying impacts on specific cognitive domains, possibly mediated by functional and biological factors.

Effects of Tabletop Games on Cognition in Older Adults: A Systematic Review and Meta-Analysis

Studies have shown that leisure activities, such as tabletop games, not only increase social interactions and reduce depression among older adults, but also help improve their cognitive function. However, the effects of tabletop games on cognition in older adults are yet to be comprehensively analyzed. The purpose of this study was to review and examine the effects of tabletop games on cognition in older adults. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were searched in seven electronic databases from their inception to December 2020. A total of 3946 studies were retrieved, among which 11 studies were systematically reviewed and 10 were meta-analyzed. In older adults with intact cognition, tabletop games had positive effects on their global cognition (standardized mean differences [SMD] = 1.36, 95% confidence intervals [CI]: 0.37-2.34, P < 0.001) and executive function (SMD = 0.47, 95% CI: 0.12-0.83, P < 0.001). In older adults with cognitive impairment, significant differences were found in global cognition (SMD = 0.53, 95% CI: 0.09-0.98, P = 0.02). Tabletop games had the characteristics of cognitive training and interpersonal interactions. After receiving tabletop game interventions, the cognitive functioning in older adults with intact cognition and those with mild cognitive impairment or dementia was improved. For older adults, in addition to improving cognitive functioning, tabletop games also increased their social participation and interactions. Systematic Review Registration: This review has been registered in the PROSPERO (CRD42021254085).

Neural substrate of a cognitive intervention program using Go game: a positron emission tomography study

BACKGROUND

Influence of cognitive intervention programs on brain activity has not been enough explored.

AIMS

The aims of the present study were to clarify changes in brain activity from a cognitive intervention program utilizing the board game "Go" and to examine the relationship between brain activity and the acquisition of Go skills.

METHODS

Eighteen community-dwelling older adults were randomly assigned either to an intervention group (IG), in which members attended 12 Go lessons either in groups or individually using tablet computers, or a control group (CG), in which members attended health education lectures unrelated to Go. Fluorine-18 fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography (PET), cognitive assessments, and Go tests were performed before and after the intervention.

RESULTS

The results showed different patterns of regional FDG uptake in both groups: regional cerebral glucose metabolism was significantly increased in the left middle temporal gyrus (MTG) and bilateral putamen (p < 0.01; cluster level) in the IG, and in the left superior frontal gyrus in the CG, (p < 0.01; cluster level). Furthermore, Go test scores were significantly improved in the IG (p < 0.05), and a significant association was observed between changes in Go test scores and glucose metabolism in the left MTG (p < 0.05).

CONCLUSIONS AND DISCUSSION

This study indicates that a cognitive intervention program using Go may enhance brain activity. Further studies with larger populations and longer observation periods are needed to clarify the neural mechanisms underlying our Go intervention program.

The effectiveness of intervention with board games: a systematic review

To examine the effectiveness of board games and programs that use board games, the present study conducted a systematic review using the PsycINFO and PubMed databases with the keywords “board game” AND “trial;” in total, 71 studies were identified. Of these 71 studies, 27 satisfied the inclusion criteria in terms of program content, intervention style, and pre–post comparisons and were subsequently reviewed. These 27 studies were divided into the following three categories regarding the effects of board games and programs that use board games: educational knowledge (11 articles), cognitive functions (11 articles), and other conditions (five articles). The effect sizes between pre- and post-tests or pre-tests and follow-up tests were 0.12–1.81 for educational knowledge, 0.04–2.60 and − 1.14 – − 0.02 for cognitive functions, 0.06–0.65 for physical activity, and − 0.87 – − 0.61 for symptoms of attention-deficit hyperactivity disorder (ADHD). The present findings showed that, as a tool, board games can be expected to improve the understanding of knowledge, enhance interpersonal interactions among participants, and increase the motivation of participants. However, because the number of published studies in this area remains limited, the possibility of using board games as treatment for clinical symptoms requires further discussion.

Can cognitive leisure activity prevent cognitive decline in older adults? A systematic review of intervention studies

The aims of this systematic review were to investigate what kind of cognitive leisure activities have been used in intervention studies targeting older adults, and whether these activities improve cognitive function or inhibit cognitive decline. Based on the PRISMA declaration, we searched keywords using three electronic databases: PubMed, PsycINFO and PsycARTICLES. Intervention studies involving cognitive leisure activities with cognitive assessments set as outcomes were included. We regarded cognitive leisure activities as activities for enjoyment or well-being that cause intellectual stimulation (e.g. reading, playing board games). To investigate the influence of each activity on cognitive domains, multicomponent programs (e.g. combined music and art) were excluded. In total, 20 studies were included in the evaluation. Consequently, intervention studies related to arts, writing, board games, reading, handicrafts, a crossword puzzle and learning computer skills were identified. Of the 20 studies, 13 showed improvement in some cognitive domain. In 12 of these 13 studies, the intervention effects were not observed in a specific cognitive domain; rather, the intervention effects were observed across multiple cognitive domains and on working memory. The results of the present review suggest that cognitive function in older adults can be improved through cognitive leisure activity interventions. Activities related to learning new skills, that cause strong intellectual stimulation and that include communication elements were considered particularly effective tools. However, as the number of studies is small, more high-quality research needs to be accumulated. Geriatr Gerontol Int 2019; 19: 469-482.

Does social interaction influence the effect of cognitive intervention program? A randomized controlled trial using Go game

OBJECTIVES

The purpose of this study is to clarify the influence of social interaction on the effect of a cognitive intervention program using Go.

METHODS

A single-blind, randomized controlled trial using a classical board game "Go" was conducted. A total of 72 community-dwelling older adults, without previous experience playing Go, were randomly assigned to three groups: (1) a face-to-face group (FG) in which members attended 12 Go group lessons held once a week; (2) a non-face-to-face group (NFG) in which members individually underwent the same Go lessons as the FG using a tablet computer; or (3) a health education control group (CG). The main outcome variable, working memory, was assessed before and after the interventions using the Visual Memory Span Test (VMST) and the Visual Memory Span Backward (VMSB) task. Go performance and additional cognitive domains were also examined.

RESULTS

Analysis of covariance revealed that VMST scores significantly improved after the intervention in both the FG and NFG (both P < .05). Compared with the CG, the effect size of the FG (Cohen's d = 0.89) was greater than that of the NFG (Cohen's d = 0.67). Although VMSB scores significantly improved after the intervention in the FG (P < .05), no significant changes were observed in other groups.

CONCLUSIONS

This study showed that Go game could improve visual working memory regardless of social interaction. Furthermore, findings suggested that playing board games face-to-face with others is more effective for cognitive function than playing alone.
