The Effects of Individualized Music Listening on Affective, Behavioral, Cognitive, and Sundowning Symptoms of Dementia in Long-Term Care Residents.

Objectives: This study aimed to replicate music's positive effects on dementia-related symptoms, determine whether a 6-month intervention would lead to greater positive outcomes than typical 3- to 4-month interventions, and examine changes in sundowning symptoms after music listening.

Methods: 282 nursing home residents with dementia listened to personalized music playlists 1-3 times weekly for 30 minutes across 6 months. Standardized assessments of affect, behavior, and cognition and direct observations of sundowning symptoms comprised the outcomes.

Results: Results documented significant improvements in residents' general neuropsychiatric symptoms, agitation, and depression across the first 3 months, but no additional improvements across the subsequent 3 months. Seven sundowning symptoms significantly improved following music listening, with some (e.g., disengagement) being more amenable to music than others (e.g., aggression).

Discussion: Results support short-term individualized music listening as an effective non-pharmacological approach for improving dementia-related symptoms in nursing home residents and suggest new applications of music-related interventions.
