Introduction: Music therapy is a practice for helping and supporting people with intellectual and relational difficulties. This study illustrated the benefits of music therapy for young people living with intellectual disabilities (YLID) in an African context. Methodology: This study investigated six young individuals with intellectual disabilities who had undergone three years of music therapy. They were participants in the inclusive non-academic training program at the National School of Arts in Dakar from 2017 to 2019. Data collection utilized individual interviews with the youths, evaluation grids from teachers and psychiatrists. Guardians provided informed consent along with the assent of the young participants. Results: The six young were aged between 18 and 30 years old, with an average age of 24.6 years. Four of the YLID were male. Three young people with intellectual disabilities had delayed psychomotor development. Observations revealed the beneficial influence of music therapy on the health and well-being of young individuals. Music played a role in alleviating stress and anxiety among youth with intellectual disabilities (YLID), enhancing their mood and mental health. It assisted in navigating challenging situations and heightened alertness among YLID. Additionally, music therapy contributed to improvements in dyslexia, fine and gross motor skills, and memory development among intellectually disabled youth, ultimately facilitating their integration into society. Conclusion: In light of our results, music therapy makes a major contribution to the empowerment of YLID. Engaging in musical activities helps young people connect with others through instrumental expression and a sense of accomplishment. By facilitating music therapy, it becomes possible to combat discrimination and stigmatization, thus promoting the social inclusion of intellectually disabled youth. Therefore, it is important to promote music therapy in Senegal to meet the needs of YLID. 展开更多

Background: Dementia is a condition with progressive cognitive dysfunction and manifestation of both behavioral and psychosocial symptoms. Non-pharmacological measures such as music therapy are gaining importance since efficacy and safety of people with dementia have been questionable for pharmacological measures. Patient’s response to music is persistent even in the later stage of dementia. Aim: This rapid review aims to identify, analyze, evaluate, and summarize the best available evidence on the effectiveness of music-based therapeutic interventions among people with dementia. Method: CINAHL Cochrane Library, internet websites of rapid review producers, and reference lists were searched to identify articles for inclusion. Two reviewers independently screened the literature search results. Effectiveness, music-based therapeutic intervention, dementia, Alzheimer’s disease, systematic review and systematic review with meta-analysis terms were used to abstract data from included studies. Main Findings: 11 SRs and SRs with meta-analysis were reviewed which revealed positive effect of music therapy on five major outcomes with 9 studies effect on behavioral outcome, 6 studies with positive effect on psychosocial outcome reducing anxiety, 6 with improved cognition, 1 study revealed with improved quality of life and 1 study revealed effect on physiological outcomes. Conclusion: Music therapy has positive effect on treatment of dementia but further studies with larger sample size and specified to single intervention should be conducted to provide generalisable and precise results on this topic. 展开更多

BACKGROUND Musical hallucinations(MH)involve the false perception of music in the absence of external stimuli which links with different etiologies.The pathomechanisms of MH encompass various conditions.The etiological classification of MH is of particular importance and offers valuable insights to understand MH,and further to develop the effective treatment of MH.Over the recent decades,more MH cases have been reported,revealing newly identified medical and psychiatric causes of MH.Functional imaging studies reveal that MH activates a wide array of brain regions.An up-to-date analysis on MH,especially on MH comorbid psychiatric conditions is warranted.AIM To propose a new classification of MH;to study the age and gender differences of MH in mental disorders;and neuropathology of MH.METHODS Literatures searches were conducted using keywords such as“music hallucination,”“music hallucination and mental illness,”“music hallucination and gender difference,”and“music hallucination and psychiatric disease”in the databases of PubMed,Google Scholar,and Web of Science.MH cases were collected and categorized based on their etiologies.The t-test and ANOVA were employed(P<0.05)to compare the age differences of MH different etiological groups.Function neuroimaging studies of neural networks regulating MH and their possible molecular mechanisms were discussed.RESULTS Among the 357 yielded publications,294 MH cases were collected.The average age of MH cases was 67.9 years,with a predominance of females(66.8%females vs 33.2%males).MH was classified into eight groups based on their etiological mechanisms.Statistical analysis of MH cases indicates varying associations with psychiatric diagnoses.CONCLUSION We carried out a more comprehensive review of MH studies.For the first time according to our knowledge,we demonstrated the psychiatric conditions linked and/or associated with MH from statistical,biological and molecular point of view. 展开更多

Non-pharmacological interventions for improved home care of persons with dementia and their family caregiver are and will be increasingly important for society. A music intervention study was performed on persons with persons with dementia and family caregiver. The persons with dementia and family caregiver were instructed to choose a daily routine for joint listening to recorded music. They selected the music they were interested in from a menu. The intervention period lasted for two months. Both persons with dementia and family caregiver provided daily saliva samples for the assessment of stress-related steroid hormones. In previous reports we have reported that the morning cortisol levels decreased significantly among the family caregiver when the intervention group was compared to a control group. In the present study we report narratives from four dyads, two of whom with beneficial effects of the music intervention, one dyad with no clear beneficial effects and one dyad with mixed results. The narratives illustrate the strong cohesive effect that the joint music listening could have, leading to improved social functioning paralleled by decreased morning cortisol levels particularly in the family caregiver. The narratives also illustrate reasons for failed effects. 展开更多

Music education under the frame name of arts education has been integrated into the primary and secondary education curriculums in Hong Kong for more than 20 years,starting from 2001,the year of launching the Learning to Learn curriculum for the reconstruction of the education system for the younger generation.Music education,embedded into the arts education,was therefore regarded as one of the key subjects to cultivate and uplift student holistic development,focusing on aesthetic skill training and moral growth development.This research was an exploration study of music teaching practices from two private international and two general public school music teachers at the primary school level.The value of this study rested on borrowing the idea of Shulman’s pedagogical content knowledge(PCK)principle to create a social constructivist music teaching framework from five commonly-used instructional methods,namely,Orff,Kodaly,Dalcrozes,Suzuki,and Gordon’s approaches.Based on the evaluations of these four case studies,hypotheses on the differences in the PCK were tested with the types of schools and found to be no difference.The preliminary results suggested that music teachers in private international schools had similar pedagogical approaches to music instruction to teachers in aided-public schools.Additionally,the modeling,guiding,and training approach was identified as a grounded teaching method for music education at the primary school level regardless of different types of schools.Other implications like the further development of the framework were discussed. 展开更多

The purpose of the article is to present several topics in Russian music of the Soviet era(roughly 1920-1990).The time that has passed since the fall of the Iron Curtain allows us to rethink and revise the cultural treasures of seven decades and reassess new research of the last decade,carried out both by people who previously gained a reputation as an authority in Soviet culture,and by scientists who came from this environment and began sharing their vision of the subject after acquiring the skills of a Western scholar.The article is based mainly on the latter research and tries to see its subject as a complete picture,albeit with missing details,so to speak,a postmodern picture that requires the reader to participate in its refinement.The methodological basis of this study is working with published sources through the critical lens of cultural anthropology as it has developed and presently looks. 展开更多
