Cognitive Intervention with Musical Stimuli Using Digital Devices on Mild Cognitive Impairment: A Pilot Study

The longitudinal relationship between levels of cognitively stimulating leisure activity and positive and negative affect among older adults with MCI

BACKGROUND

The purpose of this study was to investigate the longitudinal relationship between different levels of cognitively stimulating leisure activity (CSLA) participation and different levels of positive and negative affect among older adults with mild cognitive impairment (MCI).

METHODS

Using a repeated-measured multivariate analysis of covariance (RM-MANCOVA), this study analyzed the Health and Retirement Study (HRS) data from 2012 to 2020 (N = 5932).

RESULTS

The results presented the following. (a) The high CSLA group showed higher positive affect and lower negative affect than the mid and low groups. Also, the mid-CSLA group presented higher positive affect and lower negative affect than the low CSLA group. (b) Both positive and negative affect showed significant differences between years and indicated a continuously declining slope year by year without exceptions. (c) The high CSLA group not only presented higher positive affect and lower negative affect during the period but also solely showed a rebounding feature in the declining slope on both emotions.

CONCLUSIONS

The findings of this study provide valuable support for the design and implementation of CSLA participation programs and clinical guidelines for older adults with MCI. The results highlight the importance of determining the optimal level of CSLA engagement that is required to promote emotional health and cognitive function in this population. Healthcare professionals and clinical practitioners can leverage the insights gained from this study to develop and deliver effective CSLA interventions tailored to the specific needs and capacities of older adults with MCI.

A systematic review and network meta-analysis comparing various non-pharmacological treatments for older people with mild cognitive impairment

BACKGROUND AND OBJECTIVE

Non-pharmacological therapy appeared to alleviate Mild Cognitive Impairment (MCI) symptoms and signs, according to systematic studies. This network meta-analysis aimed to assess the impact of non-pharmacological therapies on improving cognition in individuals with MCI and identified the most effective intervention.

METHODS

We reviewed six databases in search of potentially relevant studies of non-pharmacological therapies such as Physical exercise (PE), Multidisciplinary intervention (MI), Musical therapy (MT), Cognitive training (CT), Cognitive stimulation (CS), Cognitive rehabilitation (CR)，Art therapy (AT), general psychotherapy or interpersonal therapy (IPT), and Traditional Chinese Medicine (TCM) (such as acupuncture therapy, massage, auricular-plaster and other related systems) and others. Excluded the literature such as missing full text, missing search results, or no reporting specific values and combined with the inclusion criteria and exclusion criteria in this article, the literature ultimately included in the analysis addressed the following seven non-drug therapies PE, MI, MT, CT, CS, CR, AT. Mini-mental state evaluation paired meta-analyses were undertaken by taking weighted average mean differences with confidence intervals (CI) of 95%. The network meta-analysis was conducted to compare various therapies.

RESULTS

A total of 39 randomized controlled trials, including two three-arm studies, with 3157 participants were included. PE was most likely to be the most effective intervention to slow down the cognitive ability of patients (SMD = 1.34, 95%CI: 0.80, 1.89). CS and CR had no significant effect on cognitive ability.

CONCLUSIONS

The non-pharmacological therapy had the potential to greatly promote the cognitive ability of the adult population with MCI. PE had the best chance of being the best non-pharmacological therapy. Due to the limited sample size, substantial variability among different study designs, and the potential for bias, the results should be regarded with caution. Our findings should be confirmed by future multi-center randomized controlled, high-quality large-scale studies.

The use of technology for arts-based activities in older adults living with mild cognitive impairment or dementia: A scoping review

For older adults living with mild cognitive impairment or dementia, creative arts-based activities can offer many benefits from enjoyment as leisure/recreation to an avenue to maintain cognitive, social and emotional wellbeing. With growing interest and recognition that technology could have potential to assist in delivering these activities in more accessible and personalised ways, a scoping review was undertaken to systematically examine the scientific literature for technology-assisted creative arts activities for older adults living with dementia. We searched PubMed, PsychINFO, Web of Science, Scopus and ACM Digital Library databases using keywords centering on population with dementia, an intervention using technology, and a context of creative arts, with no restrictions on the type of outcome measured. We retrieved 3739 records, with an additional 22 from hand-searching. 51 full-text articles met the inclusion and exclusion criteria. Findings of the review indicate technologies principally being designed for music activities (listening, and music-making), as well as storytelling and visual arts. The majority of devices were custom-made, with studies mainly reporting on validating the success of the device/intervention. This suggests most work in the field is currently at prototyping stage, although a few devices are now commercially available. Recommendations for future research includes involvement of participants reporting on their previous experiences in the arts and how this influences co-design choices, and inclusion of different severities of dementia in the participant/co-design group. Furthering device development past prototyping stage as well as collaboration between teams would enable comparisons to be made across different types of devices used for the same activity, and comparisons across arts-based activities that could lead to cross-disciplinary outcomes for the design of creative arts-based assistive technologies.

Immediate effects of multimodal cognitive therapy in mild cognitive impairment

BACKGROUND

Current therapeutic evidence suggests limited efficacy of the cognitive and exercise training in mild cognitive impairment (MCI) on depression, anxiety, memory retention, comprehension, calculation, concentration, orientation, dual-task performance, and sleep disorders. Nevertheless, the immediate effects of multimodal cognitive therapy (MCT) have recently developed and its individual effects remains unknown in MCI.

OBJECTIVE

This study aimed to compare the immediate effects of MCT on cognitive and psychological measures between young healthy and older adults with MCI.

METHODS

Forty young healthy and older adults with MCI underwent immediate MCT (5 minutes each), including transcranial direct current stimulation (tDCS), light therapy, computerized cognitive therapy (CCT), robotic-assisted gait training (RAGT), core breathing exercises (CBE), and music therapy. Outcome measures included memory retention, comprehension, calculation, attention, orientation, dual-task performance, awareness, depression, anxiety, and sleep disorders. The Mann-Whitney U test and Friedman's test were used at P < 0.05.

RESULTS

Significant differences in depression, anxiety, memory retention, comprehension, calculation, attention, orientation, dual-task performance, and awareness were observed between the tDCS, CCT, and music therapy groups (P < 0.05).

CONCLUSION

MCT was beneficial for mitigating depression, anxiety, memory retention, comprehension, calculation, attention, orientation, dual-task performance, and awareness.

Efficacy of ICT-based interventions in improving psychological outcomes among older adults with MCI and dementia: A systematic review and meta-analysis

The purpose of this systematic review and meta-analysis was to investigate empirical evidence about the effectiveness of Information and Communication Technology-based interventions (ICTs) on different psychological outcomes in adults aged over 60 years with Mild Cognitive Impairment (MCI) or dementia. We conducted a systematic search on Pubmed, Web of Science, Scopus, and PsycInfo with publication year between January 2010 up to April 2021. Any pre-post quantitative intervention study with at least one of the following domains examined: quality of life (QoL), psychological well-being, social interaction, engagement, mood, anxiety, stress, loneliness, self-efficacy, or self-esteem was included. The risk of bias and quality of evidence were assessed using tools based on the Cochrane Handbook for Systematic Review of Interventions criteria. Forty-eight studies with a total of 1488 participants met the selection criteria. Because of the high heterogeneity, we ran nine different random effects meta-analyses divided by outcome and type of cognitive decline which indicated that these treatments were ineffective overall, with some exceptions. Only anxiety (small effect size =-0.375 [-0.609; -0.140]) and behavioral symptoms (BS) (medium effect size =-0.585 [-1.019; -0.152]) in people with dementia (PwD) were found to change significantly. Moreover, effect sizes for QoL in dementia and for mood in people with MCI became significant when moderated by type of ICT, living situation, and experimental setting. In particular, Virtual Reality (VR) appeared to be more effective than other devices for both PwD and MCI, and nursing homes were found to be the best setting for administering these treatments. The trim and fill method found no evidence of publication bias in any of the 9 analyses. However, quality of evidence within (RoB 2, RoB 2 Crossover, ROBINS) and across (GRADE assessment) studies was low, thus these findings should be interpreted with caution. In general, ICT-based intervention can be considered a promising approach for improving anxiety and BS in PwD, and for improving QoL in PwD and mood in people with MCI, specifically when VR is used, when participants live in nursing homes, and when interventions are carried out in nursing homes.¹.

A systematic review of music interventions for the cognitive and behavioural symptoms of mild cognitive impairment (non-dementia)

Music interventions may represent an effective approach to improving symptoms and delaying progression of MCI to dementia. This review identified nine studies (8 RCT's, 1 observational study) that explored the benefits of music interventions to those with MCI. Studies included five music-playing interventions (sample size (n) ranged from 35 to 201, age ranged from 62 to 94), one music listening intervention (n = 100, mean age = 77 (music intervention) mean age = 76 (dance intervention), one music with movement intervention (n = 16, age range 65-84 years) and two music reminiscence interventions (n = 68; 72, age range = 60-85 years). Only individuals with a clinical diagnosis of MCI were included, no individuals with a diagnosis of dementia were included. Studies were limited due to their sample size, failure to consider confounding variables (i.e. socialization), inconsistency with therapist led sessions, failure to match conditions across interventions, limited follow-up period post-intervention and the tendency to focus on depression exclusively as a measure of behavioural symptoms. Different types of music interventions have differential results on cognitive and behavioural symptoms. The different pattern of brain activation and cognitive abilities which support each type of music activity (e.g. listening vs playing music) may offer some explanation towards these differences. A standardised protocol is needed for each type of music intervention to address how music interventions are studied, taking these limitations into consideration.

Case Report: Accessible Digital Musical Instrument Can Be Used for Active Music Therapy in a Person With Severe Dementia and Worsening Behavioral and Psychological Symptoms: A Case Study Over a Year and a Half

Despite the fact that accessible digital musical instruments can take into account the level of cognitive demands, previous studies have been conducted with patients with mild cognitive impairment (MCI), and it is not known whether they can be used by people with moderate to severe dementia or dementia with worsening behavioral and psychological symptoms of dementia (BPSD). The participant was an 88-year-old woman with vascular dementia (VaD) (Mini-Mental State Examination [MMSE] and Neuropsychiatric Inventory [NPI] scores: 8 and 20, respectively). Music therapy (MT) was provided twice a week for 15 min, and MT sessions spanned over 18 months. For the MT, we used the cyber musical instrument with score (Cymis), an accessible digital musical instrument; it could be played using a touch panel and switches. The cognitive function of the participant declined further, with MMSE scores of 4 after 1 year and 0 after 1.5 years. BPSD peaked with the NPI score of 54 at 1 year and declined thereafter, although only apathy remained. Despite these changes, during MT, she was able to play the accessible digital musical instrument and focus on the performance. These results suggest that even patients with severe VaD can play an accessible digital instrument and continue active music therapy even if their BPSD progress with cognitive decline.
