Dementia profoundly affects how individuals experience and react emotionally to music, but it also reveals a unique and often preserved connection to music that can transcend many cognitive declines. While dementia impairs memory, language, and reasoning, music engages multiple brain regions simultaneously, including those linked to emotion, memory, and identity, which are often less affected in the early and middle stages of the disease. This explains why music can evoke strong emotional reactions and memories even when other cognitive functions are severely compromised.
Neurologically, music activates areas such as the hippocampus, which is crucial for memory storage and recognition, and the amygdala, which processes emotional responses. In people with dementia, these brain regions can remain responsive to music, especially familiar tunes from their youth or early adulthood, typically between ages 10 and 30. This period is significant because the medial prefrontal cortex, responsible for linking emotions to personal identity, is highly active during these years, making music from this time deeply meaningful and emotionally resonant [5][2].
Research shows that listening to familiar music can strengthen neural connections in brain areas supporting memory and attention, which may help improve mood and communication in dementia patients. For example, brain imaging studies reveal that music stimulates multiple brain regions simultaneously, promoting calmness and reducing anxiety and agitation, common symptoms in dementia [2][4]. Music therapy tailored to an individual’s preferences can provide immediate, short-term relief from distress and improve attention and mood, even in advanced stages of dementia [2].
Emotionally, music can evoke joyful memories and feelings of connection. Songs linked to positive emotional memories are particularly effective at transporting individuals back to happier times, which can momentarily restore a sense of self and clarity. This emotional engagement is not just anecdotal; it reflects real neurological activity where music taps into deep-rooted circuits that remain intact despite cognitive decline [4][3]. For caregivers and families, these moments of musical connection offer valuable opportunities for interaction and emotional bonding, often easing the distress caused by the disease’s progression [1][4].
Music therapy also has behavioral benefits. It can reduce agitation, anxiety, and sundowning—a phenomenon where confusion and restlessness worsen in the late afternoon or evening. Calming rhythms and familiar melodies help regulate emotional and autonomic systems, lowering stress hormones and triggering positive feelings. This can lead to fewer behavioral disturbances and greater cooperation during daily care routines [3][5].
Moreover, music can stimulate motor memory, which is responsible for physical movements. In advanced dementia, where voluntary movement may be impaired, rhythmic music can trigger spontaneous movement and help maintain limb flexibility and activity. This motor engagement through music therapy supports both emotional well-being and physical health [5].
The emotional impact of music in dementia care is also enhanced by personalized approaches. Generic playlists may be pleasant, but music specifically chosen or created to reflect an individual’s favorite styles, memories, and life experiences triggers deeper emotional responses. Such personalized music can reignite identity, joy, and recognition, even in later stages of dementia, helping to maintain a sense of personal identity and emotional connection [4].
In addition to improving the emotional state of those with dementia, music-based interventions also benefit caregivers by reducing their distress and social isolation. Group singing and dyadic music activities (involving both the person with dementia and their caregiver) have been shown to improve mood, cognition, and quality of life for patients while alleviating caregiver burden [1].
Overall, while dementia impairs many cognitive functions, emotional reactions to music often remain robust because music engages brain areas that are relatively preserved. This unique relationship allows music to serve as a powerful therapeutic tool, evoking emotions, memories, and moments of clarity that can improve the quality of life for people living with dementia and their caregivers.
