IntroductionIncorporating technology in cognitive interventions represents an innovation, making them more accessible, flexible, and cost-effective. This will not be feasible without adequate user-technology fit. Bearing in mind the importance of developing cognitive interventions whose technology is appropriate for elderly people with cognitive impairment, the objective of this systematic review was to find evidence about usability and user experience (UX) measurements and features of stimulation, training, and cognitive rehabilitation technologies for older adults with mild cognitive impairment (MCI) or dementia.MethodThe Medline, PubMed, Scopus, ScienceDirect, and PsycINFO databases were searched for literature published in the last 10 years (2009–2019), and three researchers independently reviewed potentially eligible studies, following specific inclusion criteria. A systematic review of the studies was conducted, presenting a qualitative synthesis of usability and UX measures with their outcomes, study characteristics and features of the cognitive intervention technologies.ResultsTen studies were selected: five were cognitive stimulation and five were cognitive training. Most of them (60%) were computer-based programs with a serious game format. Efficiency and effectiveness were the most frequent measurements used for collecting objective usability data, showing that elderly people with cognitive impairment require more time (45%) and help (40%) but can complete tasks (60%). Regarding UX or subjective usability data, questionnaires and scales were the most used methods, reporting positive experience despite certain difficulties with the interface in five studies.ConclusionMeasuring usability and UX in cognitive intervention technologies for older adults with MCI or dementia provides an integrated view that can contribute to their development according to the needs and characteristics of the target population. More research is required to include this population group in usability and UX studies, as well as standardized tools and consensus on the relationship of these terms to guarantee the future effectiveness of cognitive intervention technologies.Review registrationThis review was registered in the PROSPERO (CRD42020158147) International Register of Systematic Review Protocols.

Background/Rationale: This systematic review aims to evaluate the efficacy of the nonpharmacological interventions reducing burden, psychological symptoms, and improving quality of life of caregivers of individuals with mild cognitive impairment (MCI). Method: Databases reviewed included Medline, Cochrane Library, Embase, PsycNet, AgeLine, and ProQuest Dissertations and Theses. Studies using an experimental/quasi-experimental design including nonpharmacological intervention were included. Four studies were included, and no meta-analysis was conducted. Results: Calendar training and note-taking (cognitive intervention) significantly decreased caregiver’s depressive symptoms and prevented worsening of subjective burden 6 months posttreatment. Daily engagement of meaningful activity combined with problem-solving therapy and educational material reduced depressive symptoms 3 months posttreatment. Moreover, educational intervention and social conversation phone calls decreased caregiver burden 3 months posttreatment. Conclusion: Studies suggest that nonpharmacological interventions can support caregivers of older adults with MCI, but the few published articles present some bias and are inconclusive. Randomized-controlled trials targeting specifically caregivers are needed to determine the most efficient type of interventions for those individuals.

IntroductionMild cognitive impairment is one of the consequences of ageing, causing functional disability, a poor quality of life and an increased socioeconomic expenditure. Evidence shows that patients go through a long preclinical stage in which cognitive deficits appear subtly until they reach the threshold of dementia. Non-pharmacological interventions have been gaining ground as prevention of modifiable factors of cognitive decline such as obesity, diabetes, physical inactivity or social isolation. Along these lines, Information and Communication Technologies (ICTs) can be a tool for cognitive stimulation, cognitive training and cognitive rehabilitation. The main objective of the systematic review will be to review and analyse the use of ICTs for the improvement of cognitive functions in healthy older adult population aged 50 and over, for the prevention of cognitive impairmentMethodsA systematic review will be conducted including randomised clinical trials in adults without diseases or accidents associated with cognitive impairment, and whom have used ICTs for the improvement of cognitive functions between 2010 and 2020 in English or Spanish. The articles that report data on cognitive function by domain, for example, memory or executive functions, or by test will be included. The databases Medline (PubMed), CinahlPlus, Scopus, ISI WoS, CENTRAL and IEEE Xplore will be searched. Studies that meet the inclusion criteria will be analysed according to the Cochrane RoB2 tool for risk of bias assessment.Ethics and disseminationEthical approval is not necessary as this is a systematic review. The results will be published in scientific journals, as well as in specialised congresses on the subject of study.

BACKGROUND Executive functions are one of the known cognitive abilities that decline by age. They are the high-order cognitive processes that enable an individual to concentrate, plan, and take action. Serious games, which are games developed for specific purposes other than entertainment, could play a positive role in improving executive functions. Several systematic reviews have pooled the evidence about the effectiveness of serious games in improving executive functions; however, they are limited by some weaknesses. OBJECTIVE This study aims to investigate the effectiveness of serious games in improving executive functions among elderly people with cognitive impairment. METHODS A systematic review of randomized controlled trials (RCTs) was conducted. To retrieve relevant studies, 8 electronic databases were searched. Further, reference lists of the included studies and relevant reviews were screened, and we checked studies that cited our included studies. Two reviewers independently checked the eligibility of the studies, extracted data from the included studies, assessed the risk of bias, and appraised the quality of the evidence. We used a narrative and statistical approach, as appropriate, to synthesize results of the included studies. RESULTS Out of 548 publications identified, 16 RCTs were eventually included in this review. Our meta-analyses showed that serious games are as effective as no or passive interventions in improving executive functions (P=0.29). Surprisingly, conventional exercises were more effective than serious games in improving executive functions (P=0.03). Our subgroup analysis showed that both types of serious games (cognitive training games (P=0.08) and exergames (P=0.16)) are as effective as conventional exercises in improving executive functions. No difference was found between adaptive serious games and non-adaptive serious games in improving executive functions (P=0.59). CONCLUSIONS Serious games are not superior to no or passive interventions and conventional exercises in improving executive functions among older adults with cognitive impairment. However, our findings remain inconclusive due to the low quality of the evidence, the small sample size in most included studies, and the paucity of studies included in the meta-analyses. Accordingly, until more robust evidence is available, serious games should not be offered by healthcare providers nor used by patients for improving executive functions among older adults with cognitive functions. Further reviews are needed to assess the long-term effect of serious games on specific executive functions or other cognitive abilities among people from different age groups with or without cognitive impairment.

ABSTRACT. The literature indicates that cognitive stimulation interventions have shown promising results. Abacus represents a tool with great potential in such interventions. Objectives: To carry out a systematic review of studies published in recent years that entailed the delivery of a cognitive training program using an abacus to boost target cognitive abilities of older persons and also other age groups, with or without cognitive impairment. Methods: A systematic review study was conducted in July 2020 involving PubMed, MedLine, LILACS, and SciELO databases. Results: A total of 29 studies were retrieved, of which 8 aimed to identify the effect of abacus-based mental calculation (AMC) for different age groups and to determine its applicability as a method of cognitive stimulation for older adults. In AMC technique, participants first learn to use the physical abacus (PA) and after achieving proficiency they perform calculations using a mental image of the device, manipulating the beads of the so-called mental abacus (MA). Conclusions: The number of studies addressing abacus use as a cognitive training tool was rather limited, considering the relevance of the theme. Their interventions have shown benefits for cognitive functioning of individuals of various age groups, including older adults with cognitive impairment. Future studies that involve larger samples of healthy and/or cognitively impaired older adults with a longitudinal design and a more elaborate methodological design are suggested.

Priming Paradigm

AbstractThe literature on repetition priming in Alzheimer’s disease (AD) is inconsistent, with some findings supporting spared priming while others do not. Several factors may explain these inconsistencies, including AD severity (e.g., dementia vs. Mild Cognitive Impairment; MCI) and priming paradigm-related characteristics. This systematic review and meta-analysis provides a quantitative summary of repetition priming in AD. We examined the between-group standard mean difference comparing repetition priming in AD dementia or amnestic MCI (aMCI; presumably due to AD) to controls. Thirty-two studies were selected, including 590 individuals with AD dementia, 267 individuals with amnestic MCI, and 703 controls. Our results indicated that both individuals with aMCI and AD dementia perform worse on repetition priming tasks than cognitively older adults. Paradigm-related moderators suggested that the effect size between studies comparing the combined aMCI or AD dementia group to cognitively healthy older adults was the highest for paradigms that required participants to produce, rather than identify, primes during the test phase. Our results further suggested that priming in AD is impaired for both conceptual and perceptual priming tasks. Lastly, while our results suggested that priming in AD is impaired for priming tasks that require deep processing, we were unable to draw firm conclusions about whether priming is less impaired in aMCI or AD dementia for paradigms that require shallow processing.

Abstract There is an increasing interest in using touch-screen devices to conduct cognitive training and collect measurements of cognitive performance. However, older adults often have concerns such as anxiety about using these systems and poor comprehension of language instructions (Czaja & Lee, 2007). Given that Singapore is a multilingual society, we examined the deployment of an age-friendly multi-modal touch-screen platform (a game-based application on a tablet) in a cognitive intervention research. After modification of the platform to include features such as simplified instructions, multi-level prompts with a local accent, and four different instructional languages (including local dialects), participants were less reliant on the researchers and reported fewer difficulties in comprehending the instructions. The integrity and reliability of the data collected improved as a result. In sum, multilingual age-friendly touch-screen platform can be a novel yet effective method to study cognitive interventions in the Asian older adult populations.

Purpose The purpose of this systematic review was to assess studies of treating hearing loss in older adults with cognitive impairment. Of interest to this review is identifying clinical adaptations that may be used to tailor hearing loss treatment to older adults with cognitive impairment in order to better serve this vulnerable population. Method A systematic search with controlled vocabulary and key word terms was applied to PubMed, the Cochrane Library, Embase, CINAHL, and PsycINFO. Search concepts included terms related to hearing loss and cognitive impairment. The overall search resulted in 4,945 unique references, 50 of which were eligible for full-text review and 13 of which were included in the final review. Included manuscripts were categorized according to the American Speech-Language-Hearing Association's levels of evidence and the National Institutes of Health Quality Assessment Tools. Results Only 1 study implemented a randomized controlled trial design to assess cognitive function and behavioral symptoms after treatment with hearing aids. Other quasiexperimental studies evaluated dementia-related symptoms and/or auditory function after treating hearing loss in pre/post research designs. Finally, evidence from case studies suggested that hearing loss treatment is feasible, reduces stressful communication for caregivers, and improves dementia-related behavior problems. Conclusion Based on the systematic review, evidence suggests that treating hearing loss in persons with cognitive impairment can have benefits to communication and quality of life. Because of the quasi- and nonexperimental nature of most of the evidence found in this review, further studies are necessary to understand the effect of treatment in the context of a variable and progressive disease.
