The effectiveness of group music reminiscence therapy for people thriving with dementia: A systematic review of randomized controlled trials

Abstract

Dementia is characterized by a progressive decline in cognition, behavioral and psychological symptoms (BPSD), and quality of life (QoL). The lack of curative therapies has led to a psychosocial discourse prioritizing QoL of people thriving with dementia (PTD). Group reminiscence therapy (RT) is a relatively inexpensive intervention, with music prompts being a preferred choice, owing to robust musical memory in the early disease stage. However, a synthesis of current evidence is needed to inform research and clinical use of group music RT in dementia care. Therefore, we conducted a systematic review on PubMed, Scopus, CINAHL, APA PsycInfo, and APA PsycArticles to critically appraise published randomized controlled trials examining group music RT to improve cognition, BPSD, and QoL in PTD. Of 14,725 articles, two RCTs involving 102 PTD were included. All studies used prerecorded music for group music RT. All studies were deemed of good quality, adhering to intention-to-treat analysis and assessor blinding. Based on the American Academy of Neurology guidelines, we assigned a Level C recommendation for group music RT for cognition and Level B recommendations for BPSD and QoL (ineffective). In conclusion, group music RT may be useful for symptomatic management in PTD. However, heterogeneous study designs, disease severity, dementia subtype, and outcome measures are likely barriers to meaningful clinical translation. Therefore, the rating of recommendations only serves as a point of reference. Future avenues include live performances as prompts for group music RT.
