Why do music-based interventions benefit persons with neurodegenerative disease?
Résumé
Alzheimer disease (AD) is a neurodegenerative disease impacting cognitive, emotional, and social functioning. Given the limited effectiveness of the pharmacological approach in overcoming these difficulties, the development of non-drug treatment and particularly music-based interventions appear to be an efficient tool to overcome those difficulties. However, the factors that explain their efficacy are not clarified yet. Music is a fundamental human activity that can have a strong emotional and cognitive impact. Moreover, musical interventions promote social interactions during which participants coordinate their movements to a common rhythm. In this chapter, we will discuss the idea that interpersonal coordination supported by music can improve social functioning and non-verbal communication in patients with AD. We will also propose methods to study the benefits of music interventions on aged persons in clinical context and in particular in patients with AD.
