| Summary: | <i>Objective</i>: This study aimed to assess whether a music therapy (MT) intervention could improve memory decline in older adults with and without cognitive impairment. A dual-retrieval model of episodic memory was employed to estimate memory processes. <i>Methods</i>: Forty-three older adults with a mean age of 76.49 years (<i>n</i> = 25 with Alzheimer’s disease (AD) and mixed dementia, and <i>n</i> = 18 healthy older adults) were randomly selected for the experimental and control groups. The study design was a double-blind randomized controlled clinical trial and a certified music therapist delivered the MT. The primary outcomes were measures of working memory, episodic memory, and autobiographical memory. <i>Results</i>: In the primary outcome measures, MT effects were restricted to episodic memory measures like the Figure Memory Test of the BCSB and the Speech and Sing Memory Test. In both tests, the experimental group improved from pre-test to post-test in delayed recall, but in the Speech and Sing Memory Test, the improvement was restricted to the AD and mixed dementia group. MT had no effects on the secondary outcome measures. <i>Conclusions</i>: These findings suggest that a structured MT intervention can be promising for rehabilitating episodic memory in older adults with dementia.
