Efficacy of music therapy in treatment for the patients with Alzheimer's disease

Neurologic Music Therapy's Impact on Neurological Disorders

Neurologic music therapy (NMT) represents a groundbreaking, interdisciplinary approach that combines the therapeutic properties of music with neuroscientific principles to treat a range of neurological and psychiatric conditions. This interdisciplinary approach, increasingly recognized in clinical and research settings, leverages advances in neuroimaging to explore how music affects the structure and activity of the brain. This review provides an in-depth exploration of the multifaceted effects of NMT on brain function, highlighting its role in promoting neuroplastic changes and enhancing cognitive, emotional and motor functions in diverse patient groups. This review consolidates current knowledge on NMT and provides insights into how music affects brain structure and function and the mechanisms of action. The article then discusses the application and research results of NMT in various diseases such as stroke, Alzheimer's disease and Parkinson's disease. Its potential in personalizing therapeutic interventions and its ability to improve treatment access and effectiveness in various settings are highlighted.

Remediation of cognitive and motor functions in Tunisian elderly patients with mild Alzheimer's disease: implications of music therapy and/or physical rehabilitation

The purpose of this study was to compare the effects of music therapy (MT) and/or physical rehabilitation (PR) on cognitive and motor function in elderly Tunisian male and female patients with mild Alzheimer's disease (AD). Male patients (N: 16; age: 74.19 ± 4.27 years; weight: 76.71 ± 5.22 kg) and female patients (N: 12; age: 71.46 ± 3.36 years; weight: 67.47 ± 4.31 kg) with mild AD were randomly assigned into 4 groups including control group (Co), PR group participated in physical rehabilitation, MT group received music therapy and MT + PR received both music therapy and physical rehabilitation. Participants were required to engage in the study for four months with three 60-min sessions per week. We found all scores of cognitive (MMSE, ADAS-Cog Total and the ADAS-Cog Memory subscale) and motor functions (step length, walking speed, 6MVT and BBS score) evaluated were the greatest in MT + PR compared to the other groups. Our study also demonstrated that MT has a greater effect on cognitive function, while PR has a more pronounced effect on motor function. Changes in MMSE scores were significantly positively correlated in the PR, MT and MT + PR groups with improvements in all motor functions including step length (r = 0.77), walking speed (r = 0.73), 6MVT (r = 0.75) and BBS scores (r = 0.78) in AD patients. In conclusion, the combination of MT and PR seems to be an appropriate intervention approach that needs consideration as a treatment strategy for elderly male and female patients with mild AD.

Testosterone, oxytocin and co-operation: A hypothesis for the origin and function of music

Since the time of Darwin, theories have been proposed on the origin and functions of music; however, the subject remains enigmatic. The literature shows that music is closely related to important human behaviours and abilities, namely, cognition, emotion, reward and sociality (co-operation, entrainment, empathy and altruism). Notably, studies have deduced that these behaviours are closely related to testosterone (T) and oxytocin (OXT). The association of music with important human behaviours and neurochemicals is closely related to the understanding of reproductive and social behaviours being unclear. In this paper, we describe the endocrinological functions of human social and musical behaviour and demonstrate its relationship to T and OXT. We then hypothesised that the emergence of music is associated with behavioural adaptations and emerged as humans socialised to ensure survival. Moreover, the proximal factor in the emergence of music is behavioural control (social tolerance) through the regulation of T and OXT, and the ultimate factor is group survival through co-operation. The "survival value" of music has rarely been approached from the perspective of musical behavioural endocrinology. This paper provides a new perspective on the origin and functions of music.

Salivary Testosterone and Cortisol Levels in Tunisian Elderly Male Patients With Mild Alzheimer’s Disease. Implications of Musical Therapy And/Or Physical Rehabilitation

Changes in salivary testosterone (T) and cortisol (C) levels were assessed in elderly Tunisian male patients with mild Alzheimer’s disease (AD) subjected to music therapy and/or physical rehabilitation. Male patients with mild AD (N = 26; age = 76.23 ± 4.27 years; weight: 74.76 ± 5.36 kg) were randomly assigned into four groups for three 60-min sessions per week for 4 months; including Group1 or control group (Co) (n = 6); Group2 (n = 6), participated in physical rehabilitation (PR); Group3 (n = 7), subjected to music therapy (MT) and Group4 (n = 7), participated simultaneously in music therapy and physical rehabilitation (MT + PR). Salivary T levels increased (ηp² = 0.7) and C levels decreased (ηp² = 0.69), significantly (p < 0.001) in the PR, MT and MT + PR groups compared to the Co group respectively. Also, increases in salivary T levels and decreases in C levels in MT + PR group were greater compared to the other groups. MT increased T levels (p < 0.001) and decreased C levels (p < 0.05) to a greater extent than the PR group respectively. Changes in salivary T levels were positively (r = 0.83; p < 0.001) and C levels were negatively (r = -0.86; p < 0.001) correlated in the PR, MT and MT + PR groups with changes in MMSE in AD patients. This study highlights that combination of MT and PR holds potential to treat AD.

The State of Music Therapy Studies in the Past 20 Years: A Bibliometric Analysis

Purpose: Music therapy is increasingly being used to address physical, emotional, cognitive, and social needs of individuals. However, publications on the global trends of music therapy using bibliometric analysis are rare. The study aimed to use the CiteSpace software to provide global scientific research about music therapy from 2000 to 2019.

Methods: Publications between 2000 and 2019 related to music therapy were searched from the Web of Science (WoS) database. The CiteSpace V software was used to perform co-citation analysis about authors, and visualize the collaborations between countries or regions into a network map. Linear regression was applied to analyze the overall publication trend.

Results: In this study, a total of 1,004 studies met the inclusion criteria. These works were written by 2,531 authors from 1,219 institutions. The results revealed that music therapy publications had significant growth over time because the linear regression results revealed that the percentages had a notable increase from 2000 to 2019 (t = 14.621, P < 0.001). The United States had the largest number of published studies (362 publications), along with the following outputs: citations on WoS (5,752), citations per study (15.89), and a high H-index value (37). The three keywords “efficacy,” “health,” and “older adults,” emphasized the research trends in terms of the strongest citation bursts.

Conclusions: The overall trend in music therapy is positive. The findings provide useful information for music therapy researchers to identify new directions related to collaborators, popular issues, and research frontiers. The development prospects of music therapy could be expected, and future scholars could pay attention to the clinical significance of music therapy to improve the quality of life of people.

A Review of the Clinical Evidence for Complementary and Alternative Medicine in Huntington's Disease

Background

There is a lack of published guidelines related to the use of complementary and alternative medicine (CAM) for Huntington’s disease (HD). We conducted a review of the literature to summarize the available evidence for various mind–body practices and nutraceuticals.

Methods

PubMed and Cochrane Library electronic databases were searched independently from inception to February 2019 by two independent raters. Studies were classified for the level of evidence (Class I, II, III, or IV) according to the American Academy of Neurology (AAN) classification scale.

Results

Randomized controlled trials in HD were reviewed for mind–body interventions (dance therapy, music therapy, and exercise), alternative systems (traditional Chinese medicine [TCM]), and nutraceuticals/diet (aminooxyacetic acid [AOAA], coenzyme q10, creatine, cannabinoids, alpha-tocopherol, eicosapentaenoic acid, idebenone, levocarnitine, and triheptanoin). Few studies met AAN Class I or II level of evidence for benefits, and these are highlighted.

Discussion

There is a relative paucity of clinical trials examining CAM modalities in HD when compared to other neurodegenerative disorders. Currently, there is no evidence supporting disease modification or symptom improvement with any specific dietary or nutraceutical supplement for HD. Supervised exercise and contemporary dance are safe for people with HD, but more robust studies are warranted to guide specific recommendations for these and other mind–body interventions.

Lincoln center moments: integrating accessibility and enhancement through expanding performing arts experiences

BACKGROUND

Exposure to the arts is vital to our quality of life, providing opportunities for social connection, engagement with past hobbies and perhaps most essentially in providing the potential for enhanced means of expression. For individuals with dementia and their care-givers, access to the arts can be challenging.

METHOD

This article describes a pilot program designed to enhance access by people with dementia and to provide deeper engagement with artists, therapist s and caregivers. Participants attended music and theater performances with caregivers, then attended workshops designed to deepen the experience. Workshops grouped participants by severity of dementia and measurements of engagement during and after the program were developed to assess the efficacy of the pilot program.

RESULTS

Enhanced quality of life was noted for people with dementia and the caregivers who attended the programs with them.

CONCLUSION

This project, the first of its kind, is a starting point. There has not been another to integrate professional musicians of varying genres, with people in the community with Alzheimer' s, and most particularly, by providing after-performance groups that assisted members' processing. Designing programs incorporating the arts as applicable to community-based institutions may expand their impact.

Music Intervention Approaches for Alzheimer's Disease: A Review of the Literature

Music interventions have been widely adopted as a potential non-pharmacological therapy for patients with Alzheimer's disease (AD) to treat cognitive and/or behavioral symptoms of the disease. In spite of the prevalence of such therapies, evidence for their effectiveness report mixed results in the literature. The purpose of this narrative review is to investigate the effectiveness of various intervention strategies (music therapy vs. music listening techniques) and music type used in the intervention (individualized vs. non-individualized music) on cognitive and behavioral outcomes for persons with AD. Databases were searched for studies using either active music therapy or music listening techniques over the last 10 years. These studies were in English, included persons with AD dementia, and whose protocol gathered pre- and post-intervention outcome measures. We initially identified 206 papers which were then reduced to 167 after removing duplicates. Further review yielded 13 papers which were extensively reviewed, resulting in a final sample of six papers. Our analysis of these papers suggested that, regardless of the music intervention approach, individualized music regimens provided the best outcomes for the patient. Furthermore, music listening may act as a relaxation technique and therefore provide a long-term impact for the patient, while active music therapy may acts to engage participants through social interaction and provide acute benefits. Our findings suggest that music techniques can be utilized in various ways to improve behavior and cognition.

Music-Based Therapeutic Interventions for People with Dementia: A Mini-Review

The growing population of people with dementia worldwide calls attention to the burdens associated with age-related decline that affects physiology, psychological and cognitive status, and social/emotional wellbeing. The current standards in geriatric care recommend non-pharmacological approaches to these challenges, including safe approaches to managing pain and stress, enhancing symptom relief, and fostering independent lifestyles with the highest quality of life possible. The purpose of this article is to provide definitions of music-based interventions, music therapy applications and clinician qualifications, as well as an umbrella mini-review of meta-analyses regarding music-based interventions for individuals with dementia. Our findings indicate that most descriptions of music therapy protocols in the research lack sufficient detail to enable researchers to compare and replicate studies, and clinicians to apply techniques. Definitions of music therapy and music-based interventions are inconsistent, and practitioners vary in their professional training and preparation for implementing music-based clinical strategies. We recommend that future researchers provide thorough descriptions of music therapy and music-based interventions in their protocols.

Measuring physiological responses to the arts in people with a dementia

The dementias are a group of progressive symptoms that have multiple causes, usually caused by disease or injury of the brain, affecting higher brain functions such as language, perception, memory, reasoning and mood; they can also be associated with changes in personality. Arts interventions and interaction with the arts can create meaningful, positive experiences for people with a dementia, as well as improve quality of life. Qualitative research in particular, has been able to describe the emotional responses the arts can produce, but quantifiable changes have not been well documented. Physiological measurements such as stress hormone levels and galvanic skin response show promise in being able to quantify such responses. When taken together, these can give a picture of the kinds of physiological outcomes that are associated with positive affect and improvements in mental wellbeing in the context of arts interventions. This review provides a critical overview of the studies which measure some form of physiological outcome in response to the arts or an arts intervention in people with dementia, and indicates how future research in this area can help to broaden our understanding of the effects of the arts in dementia research and care.

Music therapy is a potential intervention for cognition of Alzheimer's Disease: a mini-review

Alzheimer's Disease (AD) is a global health issue given the increasing prevalence rate and the limitations of drug effects. As a consequent, non-pharmacological interventions are of importance. Music therapy (MT) is a non-pharmacological way with a long history of use and a fine usability for dementia patients. In this review, we will summarize different techniques, diverse clinical trials, and the mechanisms of MT as it is helpful to the cognition in AD, providing reference for future research. Many articles have demonstrated that MT can reduce cognitive decline especially in autobiographical and episodic memories, psychomotor speed, executive function domains, and global cognition. MT is a promising intervention for strategy of dementia especially of AD and it must be started as early as possible. However, more evidences with prospective, randomized, blinded, uniform and rigorous methodological investigations are needed. And we should consider to combine MT with other cognitive stimulations such as dance, physical exercise, video game, art and so on.

Musical Electroacupuncture May Be a Better Choice than Electroacupuncture in a Mouse Model of Alzheimer's Disease

Objectives. To compare musical electroacupuncture and electroacupuncture in a mouse model of Alzheimer's disease. Methods. In this study, 7.5-month-old male senescence-accelerated mouse prone 8 (SAMP8) mice were used as an Alzheimer's disease animal model. In the normal control paradigm, 7.5-month-old male SAMR1 mice were used as the blank control group (N group). After 15 days of treatment, using Morris water maze test, micro-PET, and immunohistochemistry, the differences among the musical electroacupuncture (MEA), electroacupuncture (EA), Alzheimer's disease (AD), and normal (N) groups were assessed. Results. The Morris water maze test, micro-PET, and immunohistochemistry revealed that MEA and EA therapies could improve spatial learning and memory ability, glucose metabolism level in the brain, and Aβ amyloid content in the frontal lobe, compared with the AD group (P < 0.05). Moreover, MEA therapy performed better than EA treatment in decreasing amyloid-beta levels in the frontal lobe of mice with AD. Conclusion. MEA therapy may be superior to EA in treating Alzheimer's disease as demonstrated in SAMP8 mice.

Treatment of Alzheimer's disease in Iranian traditional medicine

BACKGROUND

Alzheimer's disease (AD) is a progressive neurodegenerative disease with a high prevalence in recent years. Dramatic growth in AD prevalence has increased the importance of more researches on AD treatment. History has shown that traditional medicine can be a source of inspiration to find new therapies.

OBJECTIVES

This study tried to codify the recommendations of Iranian traditional medicine (ITM) by studying the main medical manuscripts. The second purpose was to compare these findings with new medical information.

MATERIALS AND METHODS

Cardinal traditional medical and pharmacological texts from 10th to 18th century were searched for traditional terms of dementia (Nesyan, Fisad-uz-Zekr, Faramooshkari) focused on treatment methods. The findings were classified into three groups: lifestyle recommendations, dietary approaches, and drug therapies. These findings were compared with new medical findings.

RESULTS

ITM has dietary recommendations for dementia such as increasing consumption of nuts, poultry and eggs, milk, and grape products (like raisin and currant). These compounds are full of unsaturated fatty acids, cholesterol, and polyphenolic compounds. New findings suggest that these substances can help in prevention and treatment of AD. ITM has some lifestyle considerations like increasing physical and mental activities, listening to music, attending musical feasts, and smelling specific perfumes. New medical findings confirm nearly all of these recommendations. Along with the aforementioned items, treatment with natural medicines is in the first line of traditional treatment of dementia. New investigations show that many of these herbs have antioxidant, anti-inflammatory factors and acetylcholine esterase inhibitory effects. A few of them also have N-methyl-D-aspartate (NMDA) blocking activity. When these herbs are put together in traditional formulations, they can comprehensively fight against the disease.

CONCLUSIONS

More ethnopharmacological and ethnomedical studies on ITM antidementia therapy can be followed by fruitful results.

Influence of music on steroid hormones and the relationship between receptor polymorphisms and musical ability: a pilot study

Studies have shown that music confers plasticity to the brain. In a preliminary pilot study, we examined the effect of music listening on steroid hormones and the relationship between steroid hormone receptor polymorphisms and musical ability. Twenty-one subjects (10 males and 11 females) were recruited and divided into musically talented and control groups. The subjects selected (1) music they preferred (chill-inducing music) and (2) music they did not like. Before and after the experiments, saliva was collected to measure the levels of steroid hormones such as testosterone, estradiol, and cortisol. DNA was also isolated from the saliva samples to determine the androgen receptor (AR) and arginine vasopressin receptor 1A genotypes. Advanced Measures of Music Audiation (AMMA) was used to determine the musical ability of the subjects. With both types of music, the cortisol levels decreased significantly in both sexes. The testosterone (T) levels declined in males when they listened to both types of music. In females, the T levels increased in those listening to chill-inducing music but declined when they listened to music they disliked. However, these differences were not significant. The 17-beta estradiol levels increased in males with both types of music, whereas the levels increased with chill-inducing music but declined with disliked music in females. The AMMA scores were higher for the short repeat length-type AR than for the long repeat length-type. Comparisons of AR polymorphisms and T levels before the experiments showed that the T levels were within the low range in the short repeat length-type group and there was a positive relationship with the repeat length, although it was not significant. This is the first study conducted in humans to analyze the relationships between the AR gene, T levels, and musical ability.
