Comparative Efficacy of Active Group Music Intervention versus Group Music Listening in Alzheimer's Disease

Feasibility, Experiences and Short-Term Outcomes on Challenging Behaviour and Well-Being of a Partially Online Music Intervention Pilot Study for Adults With Intellectual Disabilities

BACKGROUND

During the COVID-19 pandemic we implemented a partially online music intervention to examine the feasibility, experiences and short-term outcomes on the challenging behaviour and well-being of adults with intellectual disabilities.

METHOD

This mixed-methods study included 10 participants with mild or moderate intellectual disabilities who received 16 one-hour individual music sessions in 10 weeks, either face-to-face or online. Data on feasibility and experiences from participants and music workers were collected and analysed using inductive thematic analysis. Challenging behaviour and well-being were measured before and after intervention.

RESULTS

Overall experiences were positive and concerned appreciation, positive feelings, musical abilities, attention span, relatedness and personalisation. Online experiences varied, but most participants preferred face-to-face over online sessions. After the intervention, challenging behaviour scores were better than before.

CONCLUSIONS

Engaging in a partially online music intervention is feasible for people with intellectual disabilities and seems to improve challenging behaviour. Experiences are discussed and recommendations for future online sessions are provided.

'It helps you forget your worries': A pilot study exploring music therapy in the acute hospital aged care setting

OBJECTIVES

Few studies have explored music therapy (MT) in an acute aged care inpatient setting. We aimed to assess feasibility and patient/staff perceptions of an 8-week MT program on an acute geriatric ward.

METHODS

An 8-week in-person MT program, comprising brief receptive musical interventions up to twice-weekly. All patients admitted to the aged care ward were eligible for inclusion. A hard copy survey was used to assess patient and staff perceptions of MT. Themes raised in free-text responses were manually coded within a thematic analysis approach. A mixed methods approach was used to obtain and analyse data relating to feasibility and patient and staff perceptions of the MT intervention.

RESULTS

The 8-week program ran to completion and was delivered to a median of 11 patients (IQR 9-12) each session (median 8 new/day). In total, 10 patients completed surveys, mean age 81.1 (SD 7.7); 60% were women and all had cognitive impairment. Following an MT session, eight of eight responding patients reported feeling happy and eight of eight reported they would recommend MT. Staff respondents (n = 19) reported patients appeared happy (19/19), relaxed (13/19) and all would recommend MT to other patients. Common themes were that MT was followed by improved patient behaviour and mood, and stimulated patients.

CONCLUSIONS

An acute aged care inpatient MT program proves feasible and well-received by staff and patients. Future research may focus on more robust data collection in larger sample sizes, specific types of MT and more in-depth exploration of the patient and carer experiences.

Cognitive Stimulation with Music in Older Adults with Cognitive Impairment: A Scoping Review

BACKGROUND

The use of music in cognitive interventions represents a possibility with potential worthy of further investigation in the field of aging, both in terms of prevention from dementia, in the phase of mild cognitive impairment, and in the treatment of overt dementia.

OBJECTIVES

Currently, the types of music-based interventions proposed in the literature are characterized by wide heterogeneity, which is why it is necessary to clarify which interventions present more evidence of effectiveness in stimulating different cognitive domains.

METHOD

The study was conducted in accordance with PRISMA guidelines for scoping reviews. By searching two different databases, PubMed and the Web of Science, all studies evaluating the cognitive effects of music-based interventions on people at early stages of cognitive decline (MCI or mild-to-moderate dementia) were selected.

RESULTS

The study selection included a total of 28 studies involving n = 1612 participants (mean age ranged from 69.45 to 85.3 years old). Most of the studies analyzed agree with the observation of an improvement, or at least maintenance, of global cognitive conditions (mainly represented by the results of the MMSE test) following music-based interventions, together with a series of other positive effects on verbal fluency, memory, and executive processes.

CONCLUSIONS

The results of this review suggest the introduction of music-based interventions as complementary approaches to usual cognitive treatments. Also, the use of standardized and well-defined protocols, in addition to strong methodological research approaches, is suggested. Music-based interventions are recommended in the early stages of dementia, in MCI, and in a preventive sense in healthy older adults.

Navigating Prevention: A Systematic Review of Strategies for Alzheimer's Disease in High-Risk and Affected Individuals

Alzheimer's disease (AD) remains a widespread cause of dementia globally, and its prevalence is increasing due to the aging population. Two key pathologies typically identify this neurodegenerative disease process: the accumulation of amyloid plaques and the formation of neurofibrillary tangles containing hyperphosphorylated tau. Diagnosis relies on the patient's clinical presentation meeting specific criteria, along with the use of fluid and imaging biomarkers. The current treatment focuses on addressing symptoms, with ongoing trials aiming to decrease the production and overall impact of brain pathology. Here, we explore various methods to minimize the risks of AD in patients and individuals at high risk of developing it. To address this, we carefully selected 10 articles that discuss various prevention methods used today to promote brain health, including diets that are believed to have neuroprotective properties. The study findings emphasize the importance of further strengthening the evidence and conducting larger randomized controlled trials to gain a better understanding of the potential benefits for individuals at high risk of developing AD, as well as those already diagnosed with it.

A bayesian network meta-analysis to explore modifying factors in randomized controlled trials: what works for whom to reduce depression in nursing home residents?

BACKGROUND

Reviews of depression interventions in nursing home residents resulted in positive findings. However, because of the heterogeneity of the studies, it remains unclear what works for whom. Considering moderator effects may contribute to a comprehensive understanding of depression treatment in residents. Therefore, this study aims to review depression interventions, examining moderator effects of (1) residents' factors, and (2) components specific of interventions.

METHODS

A Bayesian network meta-analysis of randomized controlled trials primarily aimed at reducing depressive symptoms among residents was conducted. First, intervention types, e.g., exercise interventions, were compared to care as usual. Second, meta-regression analyses were conducted for moderator effects of residents' factors (i.e., severity of depressive symptoms, physical dependency, and cognitive impairment) and components identified as specific to an intervention (e.g., music, creativity, positivity).

RESULTS

Our search across six databases resulted in 118 eligible studies: 16 on neurobiological interventions, 102 on non-pharmacological interventions. Compared to care as usual, cognitive interventions, such as cognitive behavioral therapy and goal-oriented therapy, showed the strongest effects (MD = -1.00, 95% CrI [-1.40 to -0.66]). Furthermore, the severity of depressive symptoms moderated the effect of interventions (ƅ = -0.63, CrI 95% [-1.04 to -0.22]), while none of fifteen identified intervention-specific components did. In residents with a depression diagnosis, there were larger effect sizes for interventions including daily structure, psychoeducation, healthy food, creativity, positivity, and an activating/encouraging environment, whereas interventions focusing on distraction and relaxation had larger effect sizes in those residents without.

CONCLUSIONS

By examining the moderator effects, we provided an integrative perspective on the observed variations in effects across different target groups, and components of depression interventions. This approach underscores the complex nature of interventions, emphasizing the need for continued transdisciplinary research, and the exploration of potential moderators. Future investigations should carefully assess residents' factors and choose interventions and their components accordingly.

Benefits of Music Therapy in the Cognitive Impairments of Alzheimer's-Type Dementia: A Systematic Review

Background/Objective: Alzheimer's disease is a condition that can cause memory, thinking, and behaviour impairments. This type of dementia affects approximately 50 million people globally. Currently, there is no remedy for this disease, but there are different treatment approaches, both pharmacological and non-pharmacological, that try to alleviate the symptoms. The remarkable fact about Alzheimer's response to music is that musical abilities can be preserved even though language could be lost. The objective of this systematic review is to assess the benefits of music therapy on cognitive impairments in older adults with Alzheimer's disease. Methods: This is a systematic review carried out following the PRISMA guidelines. The literature searches were conducted in the following databases: PubMed, SCOPUS, Cochrane Library, and Dialnet. The inclusion criteria established were as follows: randomised controlled studies and clinical trials published in English and Spanish from 2010 to 2024, patients diagnosed with dementia of the Alzheimer's type, aged 65 years or older, who had participated in music interventions and had cognitive changes. Results: Eleven studies were included in this review. They showed that music therapy interventions mainly improved memory, language, and orientation. The results of a methodological quality analysis showed that six of the articles had good methodological quality and four had excellent methodological quality. Conclusions: The results of this review suggest that treatment with music therapy improves cognitive impairments in patients with Alzheimer's disease. In addition, we can be sure that music creates a link between the patient and the specialist.

The underlying roles and neurobiological mechanisms of music-based intervention in Alzheimer's disease: A comprehensive review

Non-pharmacological therapy has gained popularity in the intervention of Alzheimer's disease (AD) due to its apparent therapeutic effectiveness and the limitation of biological drug. A wealth of research indicates that music interventions can enhance cognition, mood and behavior in individuals with AD. Nonetheless, the underlying mechanisms behind these improvements have yet to be fully and systematically delineated. This review aims to holistically review how music-based intervention (MBI) ameliorates abnormal emotion, cognition decline, and behavioral changes in AD patients. We cover several key dimensions: the regulation of MBIs on cerebral blood flow (CBF), their impact on neurotransmission (including GABAergic and monoaminergic transmissions), modulation of synaptic plasticity, and hormonal release. Additionally, we summarize the clinical applications and limitations of active music-based intervention (AMBI), passive music-based intervention (PMBI), and hybrid music-based intervention (HMBI). This thorough analysis enhances our understanding of the role of MBI in AD and supports the development of non-pharmacological therapeutic strategies.

The benefits of caregiver singing and receptive music in dementia care: a qualitative study of professional caregivers' experiences

BACKGROUND

For persons with dementia, receptive music may reduce negative expressions and increase positive ones. Caregiver singing (CS) is an intervention aimed at facilitating care situations and involves caregivers singing for or together with persons with dementia during care activities. In the literature, CS is commonly addressed as a music activity rather than a care intervention. The aim was to describe caregivers' experiences of the reactions of persons with dementia when using CS and receptive music in dementia care.

METHOD

The data comprised three focus group interviews with 12 professional caregivers in dementia care, analysed using qualitative content analysis.

RESULTS

the analysis resulted in two themes: "CS increases interaction and builds companionship" and "Receptive music soothes, awakens memories and reflects the person's self".

CONCLUSION

Both CS and receptive music was shown to have positive influences, and while the results were sometimes intertwined, CS was shown to better facilitate problematic care situations.

Effects of a music therapy and music listening intervention for nursing home residents with dementia: a randomized controlled trial

Introduction

The aim of the present study was to evaluate the effects of an individual music therapy intervention and an individual music listening intervention on neuropsychiatric symptoms and quality of life in people with dementia living in a nursing home and on professional caregiver's burden to be able to make statements about their specific value of application in clinical practice.

Methods

A multicenter single blind randomized controlled trial with three groups was performed: an individual music therapy intervention (IMTI) group (n = 49), an individual music listening intervention (IMLI) group (n = 56) and a control group (n = 53) receiving usual care. The interventions were given during three weeks, three times a week on non-consecutive days during 30-45 minutes for in total nine sessions. The endpoint of the study is the difference from baseline to interim (1,5 week), post-intervention (3 weeks) and follow-up (6 weeks) in reported scores of problem behaviour (NPI-NH) and quality of life (Qualidem) in people with dementia and occupational disruptiveness (NPI-NH) in care professionals.

Results

In total 158 people with dementia were randomized to one of the two intervention groups or the control group. Multilevel analyses demonstrated that hyperactive behaviour assessed by the NPI-NH was significantly more reduced for the IMLI group at follow up and that restless behaviour assessed by the Qualidem was significantly more reduced for the IMTI group at post and follow-up measurement compared to the control group. No significant effects between groups were found in other NPI-NH clusters or Qualidem subscales.

Conclusion

In conclusion, because we found no convincing evidence that the IMTI or IMLI is more effective than the other both interventions should be considered in clinical practice. For the future, we advise further research into the sustainability of the effects with alternative designs, like a single case experimental design.

Music Therapy as a Complementary Treatment in Patients with Dementia Associated to Alzheimer's Disease: A Systematic Review

Background

Alzheimer's disease (AD) is a complex condition that affects various aspects of a patient's life. Music therapy may be considered a beneficial supplementary tool to traditional therapies, that not fully address the range of AD manifestations.

Objective

The purpose of this systematic review is to investigate whether music therapy can have a positive impact on AD patients and on which symptoms.

Methods

The main research databases employed have been PubMed and Cochrane, using the keywords "dementia", "music therapy", "Alzheimer", "fMRI", "music", and "EEG".

Results

After removing duplicates and irrelevant studies, 23 were screened using set criteria, resulting in the final inclusion of 15 studies. The total number of participants included in these studies has been of 1,196 patients. For the fMRI analysis the search resulted in 28 studies on PubMed, two of which were included in the research; the total number of participants was of 124 individuals. The studies conducted with EEG were found using PubMed. The initial search resulted in 15 studies, but after a more accurate evaluation only 2 have been included in the analysis.

Conclusions

Even though the data currently available is not sufficient to draw conclusions supported by robust statistical power, the impact of music therapy on AD neuropsychiatric symptoms deserves great interest. Further research should be ushered, possibly multicentric studies, led with neuroimaging and other recent techniques, which can eventually open views on the music role in improving the cognitive status in AD.

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.

The impact of music listening intervention on Asia elderly with dementia: a systematic review

From an initial pool of 2303 studies, ten eligible and potential studies were selected through rigor inclusion and exclusion criteria for this systematic review to examine music therapy's effect on dementia. The review included 967 participants, with the majority being female. A significant number of studies were conducted in Taiwan. Although several cognitive ability assessment methods were employed in the selected studies, the Mini-Mental State Examination (MMSE) was the most commonly used tool for evaluating the effects of music therapy on dementia. Overall, the current review demonstrates that music therapy can be a valuable strategy for treating patients with dementia, with its outcomes including improved cognitive function and potentially slowing the progression of the disease's severity. Therefore, this study can significantly contribute to future studies and practices aimed at using music therapy to treat dementia.

Feasibility and acceptability of a group music creativity intervention for adults with varying cognitive function

Maintaining healthy cognitive functioning and delaying cognitive decline in cognitively intact and cognitive impaired adults are major research initiatives for addressing dementia disease burden. Music interventions are promising, non-pharmaceutical treatment options for preserving cognitive function and psychological health in older adults with varying levels of cognitive function. While passive, music interventions have attracted considerable attention in the abnormal cognitive aging literature, active, music interventions such as music creativity are less well-studied. Among 58 older adults with different levels of cognitive function (cognitively healthy to mild cognitive impairment), we examined the feasibility and acceptability of Project CHROMA, a Stage 1 clinical trial developed to assess the effects of a novel, music creativity curriculum on various health outcomes. Music intervention participation (93%), overall study retention (78%), and intervention satisfaction (100%) rates were comparable to other similarly designed clinical trials. Exploratory analyses using mixed-level modeling tested the efficacy of the intervention on cognitive and psychological outcomes. Compared to those in the control condition, participants in the music condition showed some improvements in cognitive functioning and socioemotional well-being. Findings suggest that a 6-week music creativity clinical trial with several multi-modal health assessments can be feasibly implemented within a sample of varying cognitive ability.

Home-based family caregiver-delivered music and reading interventions for people living with dementia (HOMESIDE trial): an international randomised controlled trial

Background

Music interventions provided by qualified therapists within residential aged care are effective at attenuating behavioural and psychological symptoms (BPSD) of people with dementia (PwD). The impact of music interventions on dementia symptom management when provided by family caregivers is unclear.

Methods

We implemented a community-based, large, pragmatic, international, superiority, single-masked randomised controlled trial to evaluate if caregiver-delivered music was superior to usual care alone (UC) on reducing BPSD of PwD measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q). The study included an active control (reading). People with dementia (NPI-Q score ≥6) and their caregiver (dyads) from one of five countries were randomly allocated to caregiver-delivered music, reading, or UC with a 1:1:1 allocation stratified by site. Caregivers received three online protocolised music or reading training sessions delivered by therapists and were recommended to provide five 30-min reading or music activities per week (minimum twice weekly) over 90-days. The NPI-Q severity assessment of PwD was completed online by masked assessors at baseline, 90- (primary) and 180-days post-randomisation and analysed on an intention-to-treat basis using a likelihood-based longitudinal data analysis model. ACTRN12618001799246; ClinicalTrials.govNCT03907748.

Findings

Between 27th November 2019 and 7th July 2022, we randomised 432 eligible of 805 screened dyads (music n = 143, reading n = 144, UC n = 145). There was no statistical or clinically important difference in the change from baseline BPSD between caregiver-delivered music (-0.15, 95% CI -1.41 to 1.10, p = 0.81) or reading (-1.12, 95% CI -2.38 to 0.14, p = 0.082) and UC alone at 90-days. No related adverse events occurred.

Interpretation

Our findings suggested that music interventions and reading interventions delivered by trained caregivers in community contexts do not decrease enduring BPSD symptoms.

Effects of music therapy on cognition, quality of life, and neuropsychiatric symptoms of patients with dementia: A systematic review and meta-analysis of randomized controlled trials

Dementia is a major cause of disability and dependency. Pharmacological interventions are commonly provided to patients with dementia to delay the deterioration of cognitive functions but cannot alter the course of disease. Nonpharmacological interventions are now attracting increasing scholarly interest. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we aim to assess the effectiveness of music-based therapies on the cognition, quality of life (QoL), and neuropsychiatric symptoms of patients with dementia through a systematic review and meta-analysis of randomized controlled trials (RCTs). The PubMed, Embase, and Cochrane databases were searched for reports of RCTs examining the effectiveness of music-based therapies for dementia published as of April 2023. A total of 674 articles were screened, and 22 trials from 21 studies (1780 patients) met the eligibility criteria. In 15 trials, music-based therapies significantly improved the cognition of patients with dementia compared with non-music therapies. In 11 trials, music-based therapies also significantly improved the QoL of patients with dementia compared with non-music therapies. In six trials, music-based therapies significantly improved patients' neuropsychiatric symptoms compared with non-music therapies. In conclusion, music-based therapy is recognized as a safe and effective alternative approach for patients with dementia.

Effect of music therapy on older adults with depression: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Depression is becoming more prevalent in older adults. Music therapy appears to have a positive effect on older adults with depression, but the effects of specific interventions (such as active music therapy and passive music therapy) are not fully known. This review aims to evaluate the therapeutic effects of music therapy and the effects of specific interventions on older adults with depression.

METHODS

A systematic search was conducted from inception to June 2022, and an updated search was conducted in July 2023 on PubMed, Web of Science, Cochrane Library, Embase, VIP, Wanfang Data, CNKI, and CBM. This review solely targeted randomized controlled trials. Two reviewers independently reviewed the retrieved studies. The risk of bias was evaluated using the Cochrane risk of bias assessment tool 2.0, and statistical analysis was made using the RevMan 5.4 software.

RESULTS

Twenty-one studies with a total of 1777 participants were included. Music therapy was beneficial in reducing depression, anxiety, and blood pressure and increasing cognitive ability (p < 0.05). Subgroup analysis showed that passive music therapy, single intervention for 60 min, individual intervention format, and total duration of 20 h had a more significant effect on depressive symptoms in older adults.

CONCLUSION

Music therapy reduces symptoms of depression and anxiety, improves blood pressure, and enhances cognitive ability in older adults with depression. Further rigorously designed studies are warranted to confirm the effects of music therapy on older adults with depression.

Does Music Intervention Improve Anxiety in Dementia Patients? A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Music interventions (MIs) have been widely used to relieve anxiety in dementia in clinical settings. However, limited meta-analysis with randomized controlled trials (RCTs) on this topic has been conducted so far. A systematic search was conducted in four major databases (PubMed, EMBASE, Web of Science, and Cochrane Library) for data provided by RCTs from the inception to February 2023. The search strategy employed the terms "anxiety AND music AND dementia OR Alzheimer's disease". Thirteen RCTs (827 participants) were included. The results showed MI reduced anxiety significantly (SMD = -0.67, p < 0.001), especially for Alzheimer's disease (p = 0.007) and Mixed (p < 0.001)-type dementia. Moreover, significant improvements in agitation (p = 0.021) and depression (p < 0.001) in dementia were observed. Additionally, several psychological mechanisms which may be associated with MI were reviewed comprehensively. In conclusion, our findings support the efficacy of MI in alleviating anxiety symptoms in dementia patients. PROSPERO Registration (ID: CRD42021276646).

The effect of music therapy on cognitive functions in patients with Alzheimer's disease: a systematic review of randomized controlled trials

BACKGROUND

The use of music interventions as a non-pharmacological therapy to improve cognitive and behavioral symptoms in Alzheimer's disease (AD) patients has gained popularity in recent years, but the evidence for their effectiveness remains inconsistent.

OBJECTIVES

To summarize the evidence of the effect of music therapy (alone or in combination with pharmacological therapies) on cognitive functions in AD patients compared to those without the intervention.

METHODS

A systematic literature search was performed in PubMed, Cochrane library, and HINARI for papers published from 1 January 2012 to 25 June 2022. All randomized controlled trials that compared music therapy with standard care or other non-musical intervention and evaluation of cognitive functions are included. Cognitive outcomes included: global cognition, memory, language, speed of information processing, verbal fluency, and attention. Quality assessment and narrative synthesis of the studies were performed.

RESULTS

A total of 8 studies out of 144 met the inclusion criteria (689 participants, mean age range 60.47-87.1). Of the total studies, 4 were conducted in Europe (2 in France, 2 in Spain), 3 in Asia (2 in China, 1 in Japan), and 1 in the USA. Quality assessment of the retrieved studies revealed that 6 out of 8 studies were of high quality. The results showed that compared to different control groups, there is an improvement in cognitive functions after music therapy application. A greater effect was shown when patients are involved in the music making when using active music intervention (AMI).

CONCLUSION

The results of this review highlight the potential benefits of music therapy as a complementary treatment option for individuals with AD and the importance of continued investigation in this field. More research is needed to fully understand the effects of music therapy, to determine the optimal intervention strategy, and to assess the long-term effects of music therapy on cognitive functions.

[Music and exercise as therapeutic resources in dementia]

Music and exercise have played a major role in the care of people with dementia for decades. The scientific evidence for such interventions is still relatively scarce but growing. The fact which has been known for nearly 10 years that brain regions associated with musical long-term memory remain intact up to advanced stages of dementia made music a major therapeutic resource in cognitive decline. Therefore, sung texts are learned and recalled better than spoken texts. Furthermore, the specific music-related stimulation of frontal brain regions has frequently shown positive effects on conspicuous behavioral disorders associated with dementia. Exercise in combination with music, in the form of dance or eurhythmics, not only seems to positively affect cognition but also balance and gait safety among patients with dementia.

The promise of music therapy for Alzheimer's disease: A review

Alzheimer's disease (AD) is a progressive neurodegenerative disease associated with cognitive decline. Memory problems are typically among the first signs of cognitive impairment in AD, and they worsen considerably as the disease progresses. However, musical memory is partially spared in patients with AD, despite severe deficits in episodic (and partly semantic) memory. AD patients can learn new songs, encode novel verbal information, and react emotionally to music. These effects of music have encouraged the use and development of music therapy (MT) for AD management. MT is easy to implement and well-tolerated by most patients and their caregivers. Effects of MT in patients with AD include improved mood, reduced depressive scores and trait anxiety, enhanced autobiographical recall, verbal fluency, and cognition. Here, we review musical memory in AD, therapeutic effects of studies using MT on AD, and potential mechanisms underlying those therapeutic effects. We argue that, because AD begins decades before the presentation of clinical symptoms, music interventions might be a promising means to delay and decelerate the neurodegeneration in individuals at risk for AD, such as individuals with genetic risk or subjective cognitive decline.

The Effect of Music-Based Intervention on General Cognitive and Executive Functions, and Episodic Memory in People with Mild Cognitive Impairment and Dementia: A Systematic Review and Meta-Analysis of Recent Randomized Controlled Trials

Background: Music-based intervention has been used as first-line non-pharmacological treatment to improve cognitive function for people with mild cognitive impairment (MCI) or dementia in clinical practice. However, evidence regarding the effect of music-based intervention on general cognitive function as well as subdomains of cognitive functions in these individuals is scarce. Objective: To evaluate the efficacy of music-based interventions on a wide range of cognitive functions in people with MCI or dementia. Method: We searched the effect of various music therapies using randomized controlled trials on cognitive function using several databases. Studies based on any type of dementia or MCI were combined. The effects of music-based intervention on each cognitive function were pooled by meta-analysis. Results: A total of 19 studies involving n = 1024 participants (mean age ranged from 60 to 87 years old) were included. We found statistically significant improvements in MMSE (general cognitive function), the Frontal Assessment Battery (executive function), and the Auditory Verbal Learning Test (episodic memory). Conclusions: This study provides positive evidence to support music-based interventions for improving a wide range of cognitive functions in older adults with MCI and dementia. Therefore, we recommend increased use of music in people’s homes, day care centers and nursing homes. This study was registered with PROSPERO, number 250383.

Music affects functional brain connectivity and is effective in the treatment of neurological disorders

In a million years, under the pressure of natural selection, hominins have acquired the abilities for vocal learning, music, and language. Music is a relevant human activity, highly effective in enhancing sociality, is a universal experience common to all known human cultures, although it varies in rhythmic and melodic complexity. It has been part of human life since the beginning of our history, or almost, and it strengthens the mother-baby relation even within the mother's womb. Music engages multiple cognitive functions, and promotes attention, concentration, imagination, creativity, elicits memories and emotions, and stimulates imagination, and harmony of movement. It changes the chemistry of the brain, by inducing the release of neurotransmitters and hormones (dopamine, serotonin, and oxytocin) and activates the reward and prosocial systems. In addition, music is also used to develop new therapies necessary to alleviate severe illness, especially neurological disorders, and brain injuries.

Music, Mind, Mood, and Mingling in Alzheimer's Disease and Related Dementias: A Scoping Review

BACKGROUND

Music-based interventions may help to alleviate neuropsychiatric symptoms of dementia and promote prosocial interactions between individuals living with dementia and their caregivers. However, current literature does not combine these evidence bases toward explanation of how music-based interventions may alleviate symptoms and promote prosocial interactions.

OBJECTIVE

We conducted a scoping review to address the following question: what do the evidence bases suggest toward how music therapy or music-based therapeutic interventions might promote prosocial interactions between individuals living with dementia and their caregivers?

METHODS

In this review we focused on: 1) quantitative and qualitative evidence of music-based therapies promoting prosocial behaviors in individuals living with dementia, and 2) potential neurobehavioral mechanisms associated with the processes involved with how music may promote prosocial interactions. Databases included PubMed, EBSCOhost's CINAHL and PsycINFO, Cochrane Library (sub-search conducted using ALOIS, the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group), Web of Science, clinicaltrials.gov, ProQuest's Biological Science Collection, the Journal of Music Therapy, Nordic Journal of Music Therapy, and Google Scholar.

RESULTS

Sixteen original research studies were included for evidence synthesis. This scoping review reveals the need to define and clarify mechanisms of prosocial interactions between individuals living with dementia and their caregivers considering biological and social factors. These mechanisms may include dynamic interactions between preserved brain regions associated with music-evoked autobiographical memory recall and shifts from negative to positive mood states.

CONCLUSION

Defining and clarifying how and to what extent music may promote prosocial behaviors using well-designed and well-controlled mixed-methods studies may positively influence the design of interventions to promote prosocial interactions with caregivers.
