Effectiveness of Exergaming in Improving Cognitive and Physical Function in People With Mild Cognitive Impairment or Dementia: Systematic Review.

ABSTRACT: BACKGROUND:Individuals with mild cognitive impairment and dementia have impaired physical and cognitive functions, leading to a reduced quality of life compared with those without such impairment. Exergaming, which is defined as a combination of exercise and gaming, is an innovative, fun, and relatively safe way to exercise in a virtual reality or gaming environment. Therefore, exergaming may help people living with mild cognitive impairment or dementia to overcome obstacles that they may experience regarding regular exercise and activities. OBJECTIVE:The aim of this systematic review was to review studies on exergaming interventions administered to elderly individuals with mild cognitive impairment and dementia, and to summarize the results related to physical and cognitive functions such as balance, gait, executive function, and episodic memory. METHODS:We searched Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, PsycINFO, Amed, and Nursing Database for articles published from the inception of the respective databases to January 2019. We included all clinical trials of exergaming interventions in individuals with mild cognitive impairment and dementia for review. The risk of bias was independently evaluated by two reviewers using the Cochrane Collaboration and Risk of Bias in Non-randomized Studies of Interventions tools. RESULTS:Ten studies involving 702 participants were included for review. There was consistent evidence from 7 studies with a low risk of bias showing statistically significant effects of exergaming on cognitive functioning in people with mild cognitive impairment and dementia. With respect to physical function, 3 of 5 full-scale studies found positive results, and the intensity of most games was classified as moderate. CONCLUSIONS:Overall, exergaming is an innovative tool for improving physical and cognitive function in people with mild cognitive impairment or dementia, although there is high heterogeneity among studies in terms of the duration, frequency, and gaming platform used. The quality of the included articles was moderate to high. More high-quality studies with more accurate outcome indicators are needed for further exploration and validation of the benefits of exergaming for this population.

Project description:This series of articles for rehabilitation in practice aims to cover a knowledge element of the rehabilitation medicine curriculum. Nevertheless, they are intended to be of interest to a multidisciplinary audience. The competency addressed in this article is an understanding of how to develop an intervention for people with mild cognitive impairment and dementia to promote their independence, stability, and physical activity.IntroductionOlder adults with dementia are at a high risk of falls. Standard interventions have not been shown to be effective in this patient population potentially due to poor consideration of dementia-specific risk factors. An intervention is required that addresses the particular needs of older people with dementia in a community setting.MethodsWe followed guidelines for the development of an intervention, which recommend a structured approach considering theory, evidence and practical issues. The process used 15 information sources. Data from literature reviews, clinician workshops, expert opinion meetings, patient-relative interviews, focus groups with people with dementia and clinicians, a cross-sectional survey of risk factors, a pre-post intervention study and case studies were included. Data were synthesized using triangulation to produce an intervention suitable for feasibility testing. Practical consideration of how an intervention could be delivered and implemented were considered from the outset.ResultsElements of the intervention included individually tailored, dementia-appropriate, balance, strength and dual-task exercises, functional training, and activities aimed at improving environmental access, delivered using a motivational approach to support adherence and long-term continuation of activity. We focussed on promoting safe activity rather than risk or prevention of falls.ConclusionWe used a systematic process to develop a dementia-specific intervention to promote activity and independence while reducing falls risk in older adults with mild dementia.

Project description:BackgroundPrevious studies suggest that physical exercise could slow dementia progression. However, evidence for the cost effectiveness of structured exercise is conflicting and based on small trials.ObjectivesThe objective of this study was to compare the cost effectiveness of a tailored, structured, moderate- to high-intensity exercise programme versus usual care in people with mild to moderate dementia.MethodsAn economic evaluation was conducted from the UK National Health Service and personal social services perspective, based on data from a large randomised controlled trial. The primary clinical outcome was the participant reported ADAS-Cog (Alzheimer's Disease Assessment Scale-Cognitive Subscale) at 12 months. Costs (£; 2014-2015 prices) were collected prospectively over a 12-month follow-up period. A bivariate regression of costs and quality-adjusted life-years (QALYs), with multiple imputation of missing data, was conducted with the view to estimating the incremental cost per QALY gained and the incremental net monetary benefit (INMB) associated with the exercise programme plus usual care versus usual care. Sensitivity analyses were undertaken to assess the impact of uncertainty surrounding aspects of the economic evaluation, and pre-specified subgroup analyses explored heterogeneity in the cost-effectiveness results.ResultsParticipants (n = 494) were randomised to exercise plus usual care or usual care only. By 12 months the mean ADAS-Cog score had worsened slightly to 25.2 (standard deviation [SD] 12.3) in the exercise arm and 23.8 (SD 10.4) in the usual care: difference - 1.4, 95% confidence interval (CI) - 2.6 to - 0.2 (p = 0.03). The mean (standard error [SE]) costs over 12 months for experimental versus control was £5945 (US$7856) versus £4597 (US$6574), respectively; (difference: £1347 [$1926]; p = 0.0426). Mean (SE) QALY estimates were 0.787 (0.012) versus 0.826 (0.019), respectively (p = 0.090). The probability that the exercise programme is cost effective was < 1% across cost-effectiveness thresholds. INMBs ranged between -£2601 (US$3719) and £2158 (US$3086) at cost-effectiveness thresholds between £15,000 (US$21,450) and £30,000 (US$42,900) per QALY. The cost-effectiveness results remained robust to several sensitivity and subgroup analyses.ConclusionsBuilding on the clinical results of the trial, which showed that the structured exercise programme evaluated does not slow cognitive impairment in people with mild to moderate dementia, this economic evaluation shows that the programme is not cost effective.

Project description:BackgroundMild cognitive impairment and cognitive impairment, no dementia, are emerging terms that encompass the clinical state between normal cognition and dementia in elderly people. Controversy surrounds their characterization, definition and application in clinical practice. In this article, we provide physicians with practical guidance on the definition, diagnosis and treatment of mild cognitive impairment and cognitive impairment, no dementia, based on recommendations from the Third Canadian Consensus Conference on the Diagnosis and Treatment of Dementia, held in March 2006.MethodsWe developed evidence-based guidelines using systematic literature searches, with specific criteria for study selection and quality assessment, and a clear and transparent decision-making process. We selected studies published from January 1996 to December 2005 that had mild cognitive impairment or cognitive impairment, no dementia, as the outcome. Subsequent to the conference, we searched for additional articles published between January 2006 and January 2008. We graded the strength of evidence using the criteria of the Canadian Task Force on Preventive Health Care.ResultsWe identified 2483 articles, of which 314 were considered to be relevant and of good or fair quality. From a synthesis of the evidence in these studies, we made 16 recommendations. In brief, family physicians should be aware that most types of dementia are preceded by a recognizable phase of mild cognitive decline. They should be familiar with the concepts of mild cognitive impairment and of cognitive impairment, no dementia. Patients with these conditions should be closely monitored because of their increased risk for dementia. Leisure activities, cognitive stimulation and physical activity could be promoted as part of a healthy lifestyle in elderly people and those with mild cognitive impairment. Vascular risk factors should be treated optimally. No other specific therapies can yet be recommended.InterpretationPhysicians will increasingly see elderly patients with mild memory loss, and learning an approach to diagnosing states such as mild cognitive impairment is now warranted. Close monitoring for progression to dementia, promotion of a healthy lifestyle and treatment of vascular risk factors are recommended for the management of patients with mild cognitive impairment.

Project description:Due to the growing number of older adults with cognitive impairment, it is essential to delay the onset and progression of cognitive decline and promote a healthy lifestyle. The rapid growth of technology has considerably advanced the field of computerized cognitive interventions. Consequently, traditional cognitive interventions are being adapted and new multimedia systems are being developed to encourage health and independent living in old age. The primary objective of this review was to identify cognitive stimulation, training and rehabilitation programs aimed at older people with mild cognitive impairment (MCI) and dementia. PsycINFO, Medline, CINAHL, Web of Science, PubMed, and CORDIS databases were searched from January 2008 to August 2018. Two researchers reviewed the potential studies individually for eligibility. Studies of computerized cognitive interventions for people with dementia and cognitive impairment were included if they clearly described objectives, users and functioning. A systematic review of the studies was carried out, providing a qualitative synthesis of the features and study characteristics of each software. Nineteen studies met the inclusion criteria, and 11 different cognitive stimulation, training, and rehabilitation programs were identified. The studies found on cognitive intervention software indicate the existence of various technological programs for people with MCI and dementia. On the overall, the programs were aimed at people with different clinical conditions, able to create specific treatments and personalized training, optimized for portable devices, and user-friendly. However, the selected programs differ from each other in terms of objectives, usage mode and characteristics, even if they were used for the same purposes. Therefore, the information obtained in the review may be relevant to distinguish between programs and select the one that best suits each user. Thus, more information about the features and context of use is needed as well as more clinical studies to be able to compare among computerized cognitive programs.
