Music Therapy as Non-Pharmacological Treatment in Alzheimer’s Disease—Effects on Memory—Systematic Review

Abstract

Alzheimer’s disease (AD) is a neurocognitive disorder characterized by gradual onset and gradual progression, presenting a wide range of symptoms, with one of its main features being episodic memory impairment, present from the early stages of the disease. Currently, there is no cure for AD, so a multidimensional approach combining pharmacology with other non-pharmacological treatments is recommended to halt or delay cognitive and functional decline in patients. In this regard, music therapy emerges as a promising non-pharmacological treatment for memory in patients with AD, as musical memory appears to be preserved, retaining the ability to recall familiar songs and the memories associated with them. Therefore, the aim of this study is to conduct a systematic review of the current state of scientific research on the effects of music therapy on the memory of patients with AD in mild and moderate stages. A search was conducted in the Google Scholar, ProQuest, Summon, Web of Science, and Scopus databases, finding 15 articles that met the inclusion and exclusion criteria. The results seem to support the use of music-based interventions for memory in patients with AD, especially regarding autobiographical memory. However, given the limitations encountered, we consider that the results pave the way for future research rather than providing solid conclusions about their effectiveness.
