Changes in Selected Cognitive and Motor Skills as Well as the Quality of Life After a 24-Week Multidimensional Music-Based Exercise Program in People With Dementia

Effects of Exercise Intervention on Functional Mobility among Older Adults with Cognitive Impairment: A Quantitative Evidence

OBJECTIVES

This meta-analysis aimed to assess the effect of exercise interventions on functional mobility among older adults with cognitive impairments such as dementia or mild cognitive impairment, followed by further investigation on the possible moderators of exercise-induced effects on this outcome.

DESIGN

A meta-analysis of controlled trials on exercise interventions reporting functional mobility outcomes was conducted. PubMed, Embase, EBSCO, SPORTDiscus, and Web of Science were searched for relevant studies published in English-language journals through July 2024.

SETTING AND PARTICIPANTS

Clinical and community settings across 15 countries, including a total of 1104 older adults with cognitive impairment, were involved in the study.

METHODS

We computed pooled effect sizes based on standardized mean difference (SMD) using the random-effects models. The subgroup analyses and meta-regression were conducted for multiple moderating variables (eg, exercise, sample, and study characteristics). The study quality was evaluated using the Physiotherapy Evidence Database Scale.

RESULTS

This meta-analysis finally included 22 studies. Results revealed that exercise interventions effectively improved functional mobility as compared with that of the control group (SMD, -0.42; 95% CI, -0.61 to -0.24; P < .001). Exercise intervention characteristics (ie, weekly training frequency and session duration) and sample characteristic (ie, percentage of women) moderated the exercise-induced effects on this interesting outcome. Subgroup analyses showed intervention with low frequency (1-2 times/wk) (SMD, -0.71; 95% CI, -1.01 to -0.42; P < .001) had a larger improvement in mobility, followed by medium frequency (SMD, -0.33; 95% CI, -0.56 to -0.10; P < .01). In addition, interventions with a session duration of > 60 minutes (SMD, -0.60; 95% CI, -0.84 to -0.36; P < .001) and 45 to 60 minutes (SMD, -0.60; 95% CI, -0.91 to -0.29; P < .001) had a significant improvement in mobility. Moreover, exercise training had a significant improvement in mobility for studies with a high percentage of women (SMD, -0.49; 95% CI, -0.67 to -0.31; P < .001).

CONCLUSIONS AND IMPLICATIONS

Exercise intervention is a promising way to improve functional mobility among older adults with cognitive impairment. Further evidence suggests that larger effects were observed in exercise intervention features of more than 45-minute session duration 1 to 3 times a week for at least 6 weeks regardless of exercise type. In addition, women benefit more from exercise interventions than men. Our study highlights that health care providers should prioritize integrating structured exercise programs into routine care for this population.

Efficacy of music-based intervention for people living with dementia in an inpatient setting: A pilot study

BACKGROUND

Pharmacological treatment of behavioral and psychological symptoms of dementia is of limited benefit. The addition of non-pharmacological interventions is often essential for optimal symptom control. Music is a viable way to help patients communicate and improve their quality of life.

OBJECTIVE

This study aims to find the most effective way to use music in a busy dementia ward.

METHODS

17 inpatients (aged 63-93 years) with a clinical diagnosis of Alzheimer's disease and dementia took part over five weeks. Music lyrics presented via free-field speakers were individualized to personal preferences. Instruments (e.g., maracas) were used in some group sessions. We used the Neuropsychiatric Inventory Questionnaire (NPI-Q) and Music in Dementia Assessment Scales (MiDAS) to evaluate patients' behavior before and after musical intervention.

RESULTS

There was a significant difference in mean NPI-Q scores before and after the music intervention. Specifically, Delusion, Motor Disturbances, and Agitation scores were significantly reduced after music intervention. This was accompanied by significant improvements in Interest, Response, and Enjoyment of MiDAS items during specific intervals.

CONCLUSIONS

Clinical professionals can successfully deliver music-based intervention to inpatients with advanced dementia to help manage their behavioral symptoms in the short term. Music-based interventions' use for inpatient wards must be further investigated as an economical and personalized non-pharmacological therapeutic tool for patients with dementia.

Digital Therapeutics for Improving Effectiveness of Pharmaceutical Drugs and Biological Products: Preclinical and Clinical Studies Supporting Development of Drug + Digital Combination Therapies for Chronic Diseases

Limitations of pharmaceutical drugs and biologics for chronic diseases (e.g., medication non-adherence, adverse effects, toxicity, or inadequate efficacy) can be mitigated by mobile medical apps, known as digital therapeutics (DTx). Authorization of adjunct DTx by the US Food and Drug Administration and draft guidelines on "prescription drug use-related software" illustrate opportunities to create drug + digital combination therapies, ultimately leading towards drug-device combination products (DTx has a status of medical devices). Digital interventions (mobile, web-based, virtual reality, and video game applications) demonstrate clinically meaningful benefits for people living with Alzheimer's disease, dementia, rheumatoid arthritis, cancer, chronic pain, epilepsy, depression, and anxiety. In the respective animal disease models, preclinical studies on environmental enrichment and other non-pharmacological modalities (physical activity, social interactions, learning, and music) as surrogates for DTx "active ingredients" also show improved outcomes. In this narrative review, we discuss how drug + digital combination therapies can impact translational research, drug discovery and development, generic drug repurposing, and gene therapies. Market-driven incentives to create drug-device combination products are illustrated by Humira® (adalimumab) facing a "patent-cliff" competition with cheaper and more effective biosimilars seamlessly integrated with DTx. In conclusion, pharma and biotech companies, patients, and healthcare professionals will benefit from accelerating integration of digital interventions with pharmacotherapies.

Inconsistent Music-Based Intervention Reporting in Dementia Studies: A Systematic Mapping Review

Background

Recent research has shown beneficial results for music-based interventions (MBIs) for persons living with Alzheimer's disease and related dementias (AD/ADRD), but reports often lack sufficient detail about the MBI methodology, which reduces replicability. A detailed checklist for best practices in how to report MBIs was created in 2011 by Robb and colleagues to remedy the lack of detail in MBI descriptions. The implementation of the checklist specifically in AD/ADRD research has not been established. Given the complexity of music and the variety of uses for research and health, specific MBI descriptions are necessary for rigorous replication and validation of study results.

Objective

This systematic mapping review utilized the "Checklist for Reporting Music-Based Interventions" to evaluate the current state of MBI descriptive specificity in AD/ADRD research.

Methods

Research articles testing MBIs and reviews of MBI efficacy published between January 2015 and August 2023 were scored using the checklist and the results were summarized.

Results

Forty-eight studies were screened, and reporting was inconsistent across the 11 checklist criteria. Ten out of 48 studies fully reported more than 5 of the 11 criteria. Only one of the 11 scoring criteria was at least partially reported across 47 of 48 studies.

Conclusions

Thorough reporting of intervention detail for MBIs remains limited in AD/ADRD MBI research. This impedes study validation, replication, and slows the progress of research and potential application of music in practice. Greater implementation of the reporting guidelines provided by Robb and colleagues would move the field of MBI research for AD/ADRD forward more quickly and efficiently.
