Music-based training programmes, such as learning how to play an instrument or sing in a choir, have been suggested as potential interventions for promoting healthy brain ageing in older adults at risk of cognitive decline because of their ability to enhance cognitive functions and potentially promote neuroplasticity. However, there is limited empirical evidence in older adults at risk of dementia, especially that evaluates both piano and singing interventions and their effects on cognition and neuroplasticity. In this protocol, we outline a study to assess the efficacy of keyboard and singing music training programmes on reducing cognitive decline and other outcomes in older adults with Mild Cognitive Impairment (MCI).
This randomised, single-blind, controlled, parallel-group trial aims to enrol 432 individuals with MCI from the community in Sydney, Australia. Participants are randomly allocated to participate in either keyboard lessons, singing lessons or a film discussion control group once a week for 3 months. The primary objective is to assess the effectiveness of two music training programmes (keyboard and choral singing) for enhancing verbal memory after 3 months compared with control. Additionally, we will examine how these music-based interventions affect other aspects of cognition, mood, sleep, overall well-being, markers of brain plasticity and blood biomarkers of Alzheimer’s disease and neurodegeneration. Tertiary objectives are to identify factors that impact the success of the interventions, such as participation rates, engagement levels and key demographic and clinical features. Outcomes are collected at baseline and at 3 and 9 months. The primary endpoint analysis will include all randomised participants to estimate the treatment effect using intention-to-treat principles. Primary and secondary outcomes will be analysed using linear mixed models and effect size measures will be calculated.
This study will be the first robust, randomised controlled trial to assess the potential and relative value of music engagement for cognitive decline in high-risk MCI individuals, as well as broader effects on other markers of mental health, well-being and neurodegeneration. Co-designed with implementation in mind, the music interventions can potentially be delivered within memory clinic or community settings.

To examine the association between caregiving context and the health and well-being of community-dwelling people with dementia (functional ability, physical function, depression, quality of life and health-related quality of life) and their informal carers (health-related quality of life) at the pre-rehabilitation stage and the potential mediating role of caregiving context variables.
Cross-sectional study.
Secondary analysis of baseline data from a randomised controlled trial of 130 dementia care dyads—the Interdisciplinary Home-based Reablement Programme (2018–2022). Bivariate analyses were applied to identify key caregiving context variables—co-residence, sole carer status, additional caring responsibilities, client-carer relationship and subjective carer burden (carer burden hereafter)—associated with health outcomes. Subsequently, multivariable linear regression models were developed. To examine carer burden, two models were run for each outcome: one with caregiving context variables and covariates, and the other adding carer burden. The mediating effects of the identified caregiving context variable were examined using post hoc mediation analysis.
Spouse/partner carer relationship was significantly associated with better client well-being, including lower depressive symptoms and higher quality of life scores compared to adult child and other relationships. Higher carer burden was strongly associated with lower functional ability, more depressive symptoms, lower quality of life for clients and lower health-related quality of life for both clients and carers. Including carer burden in regression models explained the greatest variance across most models. Carer burden fully mediated the association between additional caring responsibilities and client functional ability, and partially mediated the association between other carers and client depression.
Carer burden needs to be carefully considered in supporting the health and well-being of dementia carer dyads.
Addressing carer burden and tailoring support to carers are essential for optimising health impacts for dementia carer dyads.
