Effect of Music Therapy on Quality of Life in Geriatric Population: A Systematic Review and Meta-Analysis

The older population is susceptible to dementia, Alzheimer's and depression. A growing elderly population poses a burden on caregivers and society. If their cognitive and psychological health is maintained, they may not need to depend on others for their needs, thereby reducing the burden on caregivers. This, in turn, may lead to a decrease in the necessity for consulting healthcare providers for psychological health, subsequently reducing the overall cost of healthcare. There are numerous options for improving cognitive and mental health in the elderly, one of which is music therapy (MT). In this systematic review, we aim to demonstrate the efficacy of MT in enhancing psychological health among the geriatric population afflicted with dementia and depression. A systematic search was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across PubMed, Scopus, ScienceDirect, and Cochrane databases. The inclusion criteria were randomized controlled trials (RCTs) that explored the use of MT in elderly patients with or without depression, dementia, or Alzheimer's. Non-RCTs, retrospective and prospective observational studies, case reports, and case series were excluded. Out of 76 records identified, eight articles were selected for qualitative synthesis and three for meta-analysis. These studies, conducted between 2010 and 2020, involved a total of 605 subjects, with 330 receiving MT and the remainder serving as controls. The interventions varied in terms of music type, duration, and setting, with outcome measures including depression scales, quality of life assessments, and cognitive examinations. The meta-analysis of depression scores indicated a positive effect of MT, though a wide confidence interval warrants caution. The quality assessment revealed varying risks of bias, highlighting the need for further research to confirm the positive role of MT. In conclusion, MT emerges as a promising intervention, but it is accompanied by considerable limitations and heterogeneity among studies. This emphasizes the need for further RCTs that specifically address the identified limitations, including issues related to sample size, control group selection, and potential confounding factors. Conducting more robust research in these areas is crucial to establishing a clearer understanding of the therapeutic benefits of music in the elderly population.
