Music therapy works because it is a form of sensory stimulation that uses familiarity and feelings of safety by awakening certain parts of the human brain, the auditory cortex and the cerebrum. Think of a favorite song you had when you were younger. Even if you haven't listened to it for several years, you'll probably remember the melody, some of the lyrics, and some memories associated with it. This is essentially how music therapy works for Alzheimer's patients too. A part of the brain holds a song in memory and brings out images associated with the sounds, and this is how memory is easily affected by music therapy. “…Music stimulates the deep areas of the amygdala and hippocampus, where emotions and long-term memory are processed. Both are less susceptible to the degenerative effects of Alzheimer's than the outer cortex, the hub of complex thought. Music played at a wedding, a religious function, favorite songs from childhood, or concerts from adolescence or early adulthood can serve as cues for recalling memories. Because singing is often a part of music and speech is closely related to singing, through the musical elements in music that activate the brain, speech functions can be improved” (Shulman).
