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

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. 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 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). 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.
