“…Music therapists have investigated the impact of music engagement on various emotional, behavioral, and physiological aspects of functioning among residents with ADRD. Qualitative and quantitative outcomes indicate that individual and group engagement in music-based experiences can modify mood (Hanser & Thompson, 1994;Suzuki, 1998), improve reality orientation (Riegler, 1980;Smith--Marchese, 1994) and cognition (Bruer, Spitznagel, & Cloninger, 2007;Prickett & Moore, 1991), decrease agitation and irritability (Brotons & Marti, 2003;Brotons & Pickett--Cooper, 1996;Choi, Lee, Cheong, & Lee, 2009;Lipe, 1991;Suzuki, Kanamori, Nagasawa, Tokiko, & Takayuki, 2007;Svansdottir & Snaedel, 2006), decrease wandering (Groene, 1993), increase speech content and fluency (Brotons & Koger, 2000), reduce apathy (Holmes, Knights, Dean, Hodkinson, & Hopkins, 2006;Moore, 2010), increase positive social interaction (Brotons & Marti, 2003;Pollack & Namazi, 1992), improve physiological/immunological functioning (Kumar et al, 1999;Takahashi & Matsushita, 2006), and enhance overall quality of life (Ahonen--Eerikainen, Rippin, Sibille, Koch, & Dalby, 2007). (Additional relevant literature from 1986 to 1998 appears in Broton's chapter, "An Overview of the Music Therapy Literature Relating to Elderly People" in Music Therapy in Dementia Care [Aldridge, 2000]).…”
