Observing no effect or even negative impact of music on people living with dementia could be due to a random selection of music, fewer individuals, and the lack of a standard protocol. High heterogeneity in outcomes did not allow for clear conclusions on the benefits of music in dementia. This demands a comprehensive non-pharmacological music treatment approach to be designed for each stage of dementia to be employed alongside pharmacological treatments. This study proposes 13 gaps in the research on the health impact of music on dementia that could be studied by future researchers.
