The effects of singing interventions on quality of life, mood and levels of agitation in community-dwelling people living with dementia: A quantitative systematic review

Background and Aims: Music-based interventions have been found to benefit people living with dementia and have positive impacts on cognition and well-being. Most people with dementia live in the community and compared to people with dementia in residential care often have less access to music-based interventions. There are many forms of music interventions and singing has shown particular promise; in the realm of music interventions. It is important to determine what aspects of music interventions yield the most benefits for people with dementia. This review aimed to synthesise evidence on the impacts of singing interventions on quality of life, mood and neuropsychiatric symptoms for community-dwelling people with dementia. Methods: We systematically searched three electronic databases (PsycINFO, MEDLINE and Web of Science) for studies reporting on singing interventions with community-dwelling people with dementia. Studies were eligible for inclusion if they reported on a singing intervention with people living with dementia that included an outcome measure of quality of life, mood or agitation. Fourteen publications were identified and included in this review, with a total of n = 361 people with dementia. Results: Despite some inconsistencies across the literature, evidence suggests that singing interventions led to an improvement in mood and a reduction in agitation levels in people living with dementia. There was no strong evidence to suggest that singing interventions led to significant improvements in quality of life. Conclusions: This review highlights the potential of singing interventions as an effective psychosocial intervention for community-dwelling people with dementia. For key developments in this area, we urge that future studies include a control group where possible which will allow for more robust examinations of singing interventions and allow intervention effects to be distinguished from general deterioration in dementia symptoms over time.

Music-Evoked Nostalgia Activates Default Mode and Reward Networks Across the Lifespan

Nostalgia is a mixed emotion that is often evoked by music. Nostalgic music may induce temporary improvements in autobiographical memory in individuals with cognitive decline. However, the neural mechanism underlying music-evoked nostalgia and its associated memory improvements is unclear. With the ultimate goal of understanding how nostalgia-evoking music may help retrieve autobiographical memories in individuals with cognitive impairment, we first sought to understand the neural underpinnings of these processes in healthy younger and older adults. Methodological constraints, including the lack of personally tailored and experimentally controlled stimuli, have impeded our understanding of this mechanism. Here, we utilized an innovative machine-learning-based method to construct three categories of songs, all matched for musical features: (1) personalized nostalgic, (2) familiar non-nostalgic, and (3) unfamiliar non-nostalgic. In 57 participants (29 aged 18-35; 28 aged 60 and older), we investigated the functional neural correlates of music-evoked nostalgia using fMRI. Four main findings emerged: (1) Listening to nostalgic music, more than familiar non-nostalgic or unfamiliar music, was associated with bilateral activity in the default mode network, salience network, reward network, medial temporal lobe, and supplementary motor regions, (2) Psychophysiological interaction (PPI) models indicated that listening to nostalgic music involved increased functional connectivity of self-referential (posteromedial cortex) and affect-related regions (insula), (3) Older adults had stronger BOLD signals than younger adults in nostalgia-related regions during nostalgic listening, (4) While the BOLD response to nostalgic music in younger adults was associated with trait-level factors of nostalgia proneness and cognitive ability, the response in older adults was related to affective responses to the music. Overall, our findings serve as a foundation for understanding the neural basis of music-evoked nostalgia and its potential use in future clinical interventions.

Can a personalised music listening intervention decrease agitation in hospitalised patients with dementia? A feasibility trial

Introduction

Agitation is a common manifestation of the behavioural and psychological symptoms of dementia (BPSD). Pharmacotherapy is not the first-line management because of its potential harms, particularly in the elderly. Music as a non-pharmacological intervention for agitation has been explored in residential aged-care facilities, but few studies have been situated in hospitals. This pilot aims to evaluate the feasibility of a personalised music listening intervention for reducing agitation in hospitalised patients with dementia in a metropolitan Geriatric Evaluation and Management (GEM) unit.

Methods

Two-arm randomised control feasibility trial. Eligible patients were assigned to the music intervention or control group, with the intervention group receiving music daily between 15:00-16:00, and agitation levels measured in both groups hourly based on the Pittsburgh Agitation Score (PAS) over 5 days of hospitalisation. Post-trial semi-structured interviews assessed feasibility of the intervention.

Results

Twenty-one patients were recruited over 8 months. Interviews with staff involved indicated that the music intervention was manageable to deliver, assisted engagement with patients which increased efficiency of some clinical tasks, and challenged staff mindset around using psychotropic medication to address agitation. PAS results were inconclusive, because of underpowered numbers in this pilot study.

Conclusion

It is feasible for nursing staff to deliver a personalised music listening intervention to patients with dementia in a geriatric unit of a tertiary hospital, without compromising on usual clinical care.

Music-based interventions for people living with dementia, targeting behavioral and psychological symptoms: A scoping review

INTRODUCTION

Dementia care is a major public health issue worldwide. The management of behavioral and psychological symptoms (BPSD) is one of the hardest challenges in this context. Non-pharmacological strategies, like music-based interventions (Mbi), seem promising options, being considered low-risk, widely available and inclusive. This scoping review aimed at mapping all Mbi used in dementia care, targeting BPSD, and debriefing its components, structure and rationale. Music therapy and other therapeutic music activities were included.

METHODS

The Arksey and O'Malley framework, Cochrane recommendations and PRISMA checklist were followed. Embase, PubMed, PsycINFO, ASSIA and Humanities Index were searched from first records until the 31st of March 2020. Snowballing process and screening of relevant journals were also undertaken. A panel of experts critically guided the evidence synthesis.

RESULTS

Overall, 103 studies (34 RCT; 12 NRT; 40 Before/After studies and 17 Case Studies) met inclusion criteria. Basic elements of the Mbi, the rationale supporting its development and hypothesis tested were mostly underreported, thus hampering cross-study comparisons and generalizations. Despite this, available evidence indicates that: it is feasible to deliver Mbi to PwD at very different stages and in different settings - from community to the acute setting - even for non-music therapists; positive or neutral effects in BPSD are often reported but not without exception; individualization seems a critical factor mediating Mbi effects.

CONCLUSIONS

Detailed intervention and research reporting are essential to interpretation, replication and translation into practice. Ten years after the publication of specific reporting guidelines, this goal is not yet fully achieved in music in dementia care.

Effects of Music Therapy on Patients with Dementia-A Systematic Review

Dementia is an increasingly common syndrome and while pharmacotherapy is available, its potential benefit is limited, especially in non-cognitive outcomes. Non-pharmacotherapy such as music therapy is potentially associated with improved outcomes. We assessed the effects of music therapy on patients with dementia to evaluate its potential benefits on dementia. Two independent reviewers searched MEDLINE, EMBASE, CINAHL, CENTRAL, and ClinicalTrials.gov databases for clinical trials, using the keywords "music therapy" and "dementia". Study outcomes included cognitive function, behavioral and psychological symptoms of dementia (BPSD), and quality of life. A total of 82 studies were included, of which 43 were interventional clinical trials, and 39 were systematic reviews or meta-analyses. Significant improvements in verbal fluency occurred after music therapy, with significant reductions in anxiety, depression, and apathy. There were no significant improvements in cognition or daily functioning, and the results on quality of life and agitation were ambiguous. Limitations of studies included low patient numbers, lack of standardized music therapy, and high heterogeneity in outcomes. More large-scale clinical trials would allow for clearer conclusions on the benefits of music therapy in patients with dementia.

Live and recorded group music interventions with active participation for people with dementias: a systematic review

Background: This literature review examined the existing evidence base for the impact of both live and recorded music interventions involving active participation in a dementia population. Methodology: PsycINFO, Medline, CINAHL, Web of Science, PubMed and Cochrane Library were searched and 15 studies met inclusion criteria. Results: There was a positive impact on behavioural and psychological symptoms, quality of life, communication and some aspects of cognitive function; methodological limitations, however, make it difficult to offer firm conclusions. Interventions using recorded music resulted in more consistent positive behavioural and psychological outcomes, whereas interventions using live music reported a benefit to communication and relationships. Conclusions: Although live and recorded music showed benefits, and should be considered in dementia care, the use of different outcome measures made definitive comparisons problematic. In order to better understand mechanisms of change, one future research area should explore how group music interventions affect communication by more closely assessing processes during live and recorded music.

Are We Doing More Than We Know? Possible Mechanisms of Response to Music Therapy

Due to advances in medical knowledge the population of older adults struggling with issues of aging like Alzheimer's disease (AD), Parkinson's disease (PD), and stroke is growing. There is a need for therapeutic interventions to provide adaptive strategies to sustain quality of life, decrease neurologic impairment, and maintain or slow cognitive decline and function due to degenerative neurologic diseases. Musical interventions with adults with cognitive impairments have received increased attention over the past few years, such as the value of personalized music listening in the iPod project for AD (1); music as a tool to decrease agitation and anxiety in dementia (2); and music to aid in episodic memory (3); Rhythmic Auditory Stimulation as rehabilitation for PD (4); and recently the potential of 40 Hz sensory brain stimulation with AD and PD (5, 6). These approaches indicate the expanding scope and efficacy of music therapy and the potential mechanisms involved. This paper explicates a four-level model of mechanisms of music response (7, 8) that may help understand current music therapy approaches and treatments and help focus future research. Each level will be illustrated with research and suggestions for research directions.

Musical intervention for patients with dementia: a meta-analysis

AIMS AND OBJECTIVES

To provide a meta-analysis of the effects of music interventions on patients with dementia, separating, for the first time, between different types of interventions and different outcome measures, namely affective, behavioural, cognitive and physiological.

BACKGROUND

Music therapy is an attractive form of intervention for the growing number of demented patients, for whom pharmacological interventions are not always effective and may lead to undesired side effects. While music is more frequently applied in clinical settings for each year, no meta-analysis has considered effects of music interventions on affective, behavioural, cognitive and physiological outcomes separately.

DESIGN

A standard meta-analysis approach was applied.

METHODS

We include all original studies found for the key words music and dementia. Mean effect sizes and confidence intervals are computed from study effect sizes according to standard methods, and these are considered for various common types of music interventions separately.

RESULTS

Nineteen studies with a total of 478 dementia patients exhibit effect sizes ranging from 0·04-4·56 (M = 1·04). Many of these indicate large positive effects on behavioural, cognitive and physiological outcome measures, and medium effects on affective measures.

CONCLUSIONS

Music interventions seem to be effective and have the potential of increasing the quality of life for patients with dementia. Many studies in this area suffer from poor methodological quality, which limits the reach of meta-analysis and the strength and generalisability of these conclusions.

RELEVANCE TO CLINICAL PRACTICE

Being inexpensive and largely without adverse side effects, current knowledge seems to indicate that music interventions can be recommended for patients in all stages of dementia.

Familiar music as an enhancer of self-consciousness in patients with Alzheimer's disease

The main objective of this paper is to examine the impact of familiar music on self-consciousness (SC) in patients with Alzheimer's disease (AD). For this purpose, two AD groups of 20 patients matched by age, educational level, gender, illness duration, and cognitive state were assessed using an SC questionnaire before and after music intervention. The SC questionnaire measured several aspects: personal identity, anosognosia, affective state, body representation, prospective memory, introspection and moral judgments. One AD group received familiar music stimulation and another AD group unfamiliar music stimulation over three months. The AD patients who received a familiar music intervention showed a stabilization or improvement in aspects of SC. By contrast, control AD group showed a deterioration of most of the SC aspects after unfamiliar music stimulation, except the SC aspects of body representation and affective state. Familiar music stimulation could be considered as an enhancer of SC in patients with Alzheimer's disease.

Comparative analysis of two musical genres within a multisensory environmental intervention

PURPOSE

The purpose of this study was to determine if there were any differences in the behavioral responses of persons with dementia while listening to nonreligious and religious music within a multisensory environment.

RESEARCH DESIGN

A within-subjects, repeated measures design was used.

METHOD

Participants were exposed to both musical genres during multiple sessions over a 4-week period. Neuropsychiatric symptoms were recorded before and after the musical intervention. Behavioral responses to the music were recorded while listening to the music.

FINDINGS

No significant difference was found between the numbers of neuropsychiatric behaviors observed before and after the participants listened to the nonreligious and religious music. A significant difference was found between the musical interventions as a whole and the number of agitated behaviors before and after intervention. No significant difference was found in the observed behavioral responses with the nonreligious and religious music.

CONCLUSIONS

Music can be a useful intervention to reduce neuropsychiatric symptoms in persons with dementia.

The effectiveness of adult day services for older adults: a review of the literature from 2000 to 2011

Adult Day Service (ADS) centers offer a variety of services to meet the needs of older adults and their caregivers. During the last decade, ADS has received increased attention due to shifts in policy toward home and community-based services for an aging population. This article reviews the effectiveness of ADS from 2000 to the present, with particular attention given to caregiver and participant outcomes, health care utilization, and future directions in ADS research. Multiple databases were searched to identify relevant research and 61 articles were selected for review based on inclusion criteria. The results of this review emphasize the need to implement and test more specific interventions targeting the needs of the ADS population.

Using Photovoice with people with early-stage Alzheimer’s disease: A discussion of methodology

Many scholars and activists have challenged researchers to do research ‘with’ not ‘for’ or ‘on’ people with Alzheimer’s disease and related dementias. Photovoice is a relatively new qualitative methodology that involves giving cameras to participants to record and document their experiences in ways that can create change. In this study, the Photovoice method was used with a group of participants in early stages Alzheimer’s disease to explore the use of Photovoice as a methodology with this population. Specifically, I was hoping to understand how Photovoice could be used as a methodology with this group, and to examine the benefits and challenges of using Photovoice with people with Alzheimer’s disease. This paper discusses some of the practical challenges arising out of using this methodology with people with early stage Alzheimer’s disease as well as some of the issues surrounding research ethics, consent, and capacity.

Practical implications of Procedural and Emotional Religion Activity Therapy for nursing

Procedural and Emotional Religious Activity Therapy encapsulates an approach to engaging older adults with Alzheimer's disease in meaningful activities that can be performed within the parameters of their cognitive functioning. Alzheimer's disease disrupts some brain structures more than others, resulting in a disproportionate loss of certain cognitive abilities. Explicit (conscious) memory skills are disrupted first, followed by implicit (unconscious) memory skills, and lastly emotional memory. Activities relying more on implicit and emotional memory, such as specially selected religious activities, are more likely to be used by patients. Steps and caveats of using this approach are provided.

An investigation of long-term effects of group music therapy on agitation levels of people with Alzheimer's Disease

This study aimed to investigate the long-term effects of group music therapy on agitation manifested by nursing home residents with Alzheimer's disease. A non-randomised experimental design was employed with one group receiving weekly music therapy (n = 26) and another group receiving standard nursing home care (n = 19). Agitation levels were measured five times over one year using the Cohen-Mansfield Agitation Inventory (Cohen-Mansfield, J. (1989). Agitation in the elderly. In N. Billig & P. V. Rabins (Eds.), Issues in geriatric psychiatry (pp. 101-113). Basel, Switzerland: Karger). Although music therapy participants showed short-term reductions in agitation, there were no significant differences between the groups in the range, frequency, and severity of agitated behaviours manifested over time. Multiple measures of treatment efficacy are necessary to better understand the long-term effects music therapy programs have on this population.

The Therapeutic Use of Music on Agitated Behavior in Those With Dementia

Clinically, nursing has long recognized dementia behaviors--agitation, aggression, wandering, and general confusion--to be a significant patient problem as well as a major stress to nursing staff and caregivers. Although there is no cure, much can be done to improve these patients' daily care and, ultimately, their quality of life.

Overview of Alzheimer's disease

In conclusion, many researchers from multiple disciplines are addressing AD at many levels, ranging from prevention, to cellular alterations, to treatment modalities, and coping and care giving with the consequences of the ravages left by the disease. Although much has been learned in the last several decades of active research, much remains to be learned. In its current status, AD is a chronic disease without a cure, which provides ample opportunities for nursing management throughout the course progression.
