It’s one of the most moving moments families describe in dementia care: Their loved one who struggles to recognize faces suddenly lights up when a familiar song begins. They may sing every lyric, tap along to the rhythm or make eye contact in ways they haven’t in months.
These moments feel miraculous, but they also have a neurological explanation. Researchers have spent years working to understand why music reaches people when other forms of communication can’t.
“Music memory works differently than other memories in the brain,” says Dr. Sanam Hafeez, a New York City neuropsychologist and director of Comprehend the Mind, a neuropsychology practice in New York City. “Neural networks linked to familiar music are more dispersed throughout the brain — the basal ganglia, the cerebellum and areas of the frontal cortex that deal with procedural and emotional memory. These are regions that are less susceptible to the disease. That’s why the lights can come back on, if only for a while.”
If you’re researching memory care options for a loved one with dementia or Alzheimer’s, you’ve probably heard that music therapy can help. But what does the research actually say? Here’s what experts say music therapy can and can’t do, and how it fits into dementia care today.
Key takeaways
- Music therapy can reduce agitation, anxiety and depression in people with dementia, helping create moments of connection even in later stages of the disease. Research supports short-term emotional and behavioral benefits, though it is not a cure or disease treatment.
- Musical memory is processed differently in the brain than other memories, which is why people who struggle to recognize loved ones may still sing songs learned decades earlier.
- Both structured music therapy and simply playing familiar music can help. The biggest difference is clinical intention and guidance from a trained therapist.
- Personalization is crucial. Music that holds specific emotional meaning for your loved one (such as songs from their teens and twenties and songs tied to big life moments) will consistently outperform generic “relaxing music” playlists.
Why does music memory often survive dementia?
Most of what dementia takes from us first — names, faces, recent events — depends on a healthy hippocampus. The hippocampus is one of the first regions of the brain that Alzheimer’s destroys.
Music, however, relies on broader brain systems. Hafeez explains that familiar songs activate multiple areas at once, including regions tied to movement, emotion and procedural memory.
“The basal ganglia plays a critical role in our perception of rhythm and timing and remains relatively intact for longer,” she says. “The cerebellum helps create music’s predictive quality, and the amygdala encodes the emotion we associate with experiences.”
Because music draws on so many systems simultaneously, Alzheimer’s would need to affect far more brain regions before musical memory disappears.
What is the “reminiscence bump”?
Hafeez says songs learned during adolescence and young adulthood are especially powerful, since they’re encoded during what researchers call the “reminiscence bump,” a life stage when emotions are experienced more intensely and memories form more strongly.
The result: music can access emotional and procedural memory even when cognitive recall fails.
“When that man hears his song from 1962, he’s not recalling it like he would recall a fact,” says Hafeez. “It’s more akin to muscle memory. The melody taps into something older and more primitive than our cognitive brain.”
Why music can calm anxiety and agitation
Dementia-related agitation often stems from confusion, overstimulation or difficulty communicating needs. Music is able to reach emotional systems when language can’t.
“Music with a regular, moderate rhythm can lower heart rate and decrease cortisol levels, taking the body out of fight-or-flight mode,” says Hafeez.
Familiar songs also carry decades of emotional associations tied to safety and identity — much like reminiscence therapy, which uses memories to support connection and well-being.
“This is why someone who may not be able to track a conversation can start rocking back and forth contentedly when their favorite song starts playing,” says Hafeez.
What research says music therapy can realistically improve
Experts emphasize that music therapy does not treat or slow dementia itself. However, evidence strongly supports its impact on quality of life.
“The evidence base for music therapy in dementia is robust in some areas and fairly slim in others,” says Hafeez. “Researchers are relatively sure of its value for short-term emotional and behavioral outcomes.”
Hafeez says studies consistently show that music therapy can:
- Reduce agitation and distress.
- Decrease anxiety and depressive symptoms.
- Improve mood and social engagement.
- Help caregivers manage challenging moments more easily.
Hafeez adds that some findings do suggest possible cognitive benefits, but research remains inconclusive.
“We would love music therapy to slow cognitive decline, and that research is ongoing,” she says. “Currently, there simply isn’t enough evidence to make that claim with confidence.”
Chris Shelley, memory care director at 10 Wilmington Place, a senior living community in Dayton, Ohio, sees similar outcomes in day-to-day practice.
“When a resident with dementia is no longer able to remember many things from their life story, music can often trigger something,” he says. “Some residents may barely speak anymore but then hear a familiar song and sing or even just hum along with it.”
Shelley says staff and families at 10 Wilmington Place report improvements in mood and anxiety, and that music programming sometimes even reduces the need for certain behavioral medications.
Music therapy vs. playing familiar music: What’s the difference?
You may be wondering if you actually need a board-certified music therapist, or if it’s enough to simply put your loved one’s favorite playlist on and listen together.
Both approaches have value, and each is suited to different goals.
Eric Lebowitz, a board-certified music therapist at Invibecat, a creative arts therapy practice in Westchester County, New York, explains the key distinction: “The biggest differentiator between music therapy and simply playing familiar music is often the therapeutic relationship and clinical intention.”
Playing familiar music can help:
- Create a calming or uplifting atmosphere.
- Support a routine (wake-up, mealtimes, wind-down).
- Encourage motivation.
- Provide engagement and entertainment.
Formal music therapy led by a trained therapist goes further, adding:
- Individualized clinical goals.
- Therapeutic assessment and adaptation.
- Structured interaction guided by a trained therapist.
“In memory care settings, a trained music therapist can meet people where they are in a way that respectfully acknowledges any limitations while still celebrating the individual and cultivating self-esteem,” says Lebowitz.
“Neural networks linked to familiar music are more dispersed throughout the brain. These are regions that are less susceptible to the disease. That’s why the lights can come back on, if only for a while.”

What does a music therapy session in memory care actually look like?
If you’re unfamiliar with music therapy in a memory care setting, it may be difficult to imagine how a group session might look. Lebowitz, who facilitates both individual and group music therapy for people with dementia, says sessions typically follow an intentional yet flexible structure designed to encourage participation and connection.
Lebowitz says he begins sessions with soft background music and clear group guidelines focused on joy and self-kindness. Each participant is greeted individually and invited to choose an instrument, offering both autonomy and gentle physical engagement.
A typical session may include:
- A simple “hello” song to establish comfort.
- Singing familiar songs together.
- Playing instruments or improvising.
- Movement or dancing.
- Discussion and emotional expression.
- Group song choices through voting.
- A closing “goodbye” song ritual.
These rituals help orient participants and foster a sense of reassuring predictability.
“I often see smiles, eye contact, singing, laughter and connection,” says Lebowitz. “Each one of these displays is meaningful, especially for someone living with dementia.”
He adds that when families are present and get to witness these moments, they often experience relief as well.
“It helps them in their grief and mourning so when they reflect on this difficult time there are still positive memories.”
Why personalization matters so much
Research consistently shows that recognizable, personally meaningful music produces stronger responses than generic, unfamiliar background music.
“Personalizing music is akin to speaking the same language,” says Lebowitz. “Imagine being in a foreign place where no one speaks your language, and then you hear your native tongue. The familiarity in an unfamiliar place can be a monumental relief. A familiar song can have the same effect.”
Shelley starts the personalization process at intake. “We can’t just ask if the resident enjoys music,” he says. “We need to find out what kinds of music, favorite artists and down to their favorite songs. The more we know about the music they like, the more therapeutic it will be for that resident.”
Hafeez echoes this sentiment and notes that it’s often the families sharing this information. “Families are often better equipped than clinicians to know what that music will be. Consider them partners in that way.”
What to ask a memory care facility about their music programming
If you’re evaluating memory care communities for a loved one, ask specifically about music programming. Shelley recommends looking for facilities where music is woven into daily life and not just offered as an occasional activity or service.
Questions worth asking:
- Is music part of the daily programming, not just special events?
- Does the facility work with a board-certified music therapist? If so, how often?
- How do you personalize music for individual residents?
- What do you ask families about their loved one’s musical history at intake?
- Are family members welcome to attend or observe music therapy sessions?
To find a credentialed music therapist, look for the MT-BC designation (Music Therapist-Board Certified). The American Music Therapy Association maintains a national directory.
How families can use music intentionally at home
You don’t need a therapist in the room to use music to bring comfort and joy to your loved one. Lebowitz offers several easy-to-implement approaches for family caregivers, rooted in the same principles that guide clinical music therapy:
Anchor music to routines
Pair specific songs with consistent times of day to provide orientation and predictability. “Songs can be played to reinforce wake-up times, meal times, bed times and activities of daily living,” says Lebowitz.
Use music to set the mood
Lebowitz explains that soft, slow instrumental music can help ease the transition to bed, while upbeat music can make exercise or other activities feel less arduous. “Through exploration and experimentation, you can learn what kind of music stimulates different moods.”
Let music provide motivation
Lebowitz suggests using upbeat songs to make physical activity more engaging. “It’s amazing how one’s range of motion can improve just by changing from asking one to raise their hands versus giving them a mallet and drum to reach and aim for.”
Make it an activity, not just background noise
Listening together, following along in a lyric book, gentle dancing or learning the history of a beloved song can all deepen the experience, much like other activities for seniors with dementia that focus on engagement and connection.
Find the right songs
Songs from your loved one’s adolescence to early adulthood tend to be most powerful. Lebowitz suggests searching for playlists by era and region or starting with songs you know hold meaning for them.
What music therapy can’t do
Experts stress the importance of setting realistic expectations. Shelley states it plainly: “Everyone has to remember that nothing is ever 100%.”
Music can’t stop the progression of dementia. Hafeez explains that effects on agitation and mood, while real, may not last long after a session ends. Not every person will respond the same way, and even a loved one’s favorite song may not reach them on a difficult day.
“It can be genuinely beneficial for quality of life and is worth utilizing,” she says. “Scientists are still understanding what it does change, for whom, and how long those effects may last.”
The most useful frame, Hafeez suggests, is to think of music less as a treatment and more as a tool: “Inexpensive, low-risk and often more potent than we realize when used appropriately.”
When music is built into the daily routine, matched to your loved one’s personal history and incorporated alongside medical management, social connection and environmental support, that’s when it tends to have the most impact. Even when it can’t fix anything, it can still create beautiful moments of connection.
For families navigating dementia, those moments are often the ones that matter most.
