Effect of Music Therapy on Agitation in Dementia: A Controlled Study

Dementia affects hundreds of thousands of Australians, and behavioural symptoms such as agitation are among the most distressing aspects of the condition. In aged care homes from Brisbane to Perth, frontline staff routinely seek non-pharmacological ways to ease restlessness, calling out, and resistance to personal care. Music therapy has emerged as one of the most promising gentle interventions, drawing on preserved musical memory even as other cognitive abilities decline.

A controlled trial across Queensland residential facilities has added to the evidence supporting this approach. Researchers tracked how structured, individualised music sessions affected agitation among residents with moderate to severe dementia, comparing outcomes with a control group receiving standard care alone. The results offer practical guidance for clinicians, families, and aged care providers weighing up how to embed therapeutic music into daily routines.

What Agitation Looks Like in Dementia

Agitation is not a single behaviour but a cluster of responses including verbal disruption, repetitive movements, wandering, and physical resistance. For someone with dementia, these behaviours often communicate unmet needs such as pain, boredom, fear, or overstimulation, even when the person can no longer articulate the cause. In Australian residential facilities, staff describe agitation as the single biggest trigger for psychotropic medication use, which carries serious risks including falls, stroke, and accelerated cognitive decline.

Recognising agitation as a form of communication rather than a symptom to be suppressed has shaped contemporary dementia care guidelines. National frameworks now emphasise person-centred approaches that look for triggers and respond with supportive strategies before reaching for sedatives. Music therapy fits naturally within this philosophy because it engages parts of the brain, particularly those tied to rhythm and familiar melody, that often remain accessible long after other capacities fade.

How Music Therapy Reaches the Brain

The therapeutic use of music is thought to work through several overlapping pathways. Familiar songs can trigger autobiographical memories, prompting moments of lucidity and emotional connection that reduce anxiety. Rhythmic elements appear to regulate arousal and breathing, helping the nervous system settle into a calmer state. Singing and gentle movement can also offer an outlet for expression when verbal communication becomes difficult.

Neuroimaging studies suggest music activates widespread brain networks, including regions affected relatively late in dementia progression. This may explain why even people with significant impairment can still recognise a hymn from their wedding day or a song their parents sang. Australian music therapists draw on this preserved capacity, building sessions around personally meaningful repertoire rather than generic playlists.

Inside the Controlled Study

The Queensland trial recruited 128 residents from six aged care facilities across the greater Brisbane and Sunshine Coast regions. Participants had a confirmed diagnosis of major neurocognitive disorder and scored above a set threshold on a standard agitation scale during a two-week baseline period. They were randomly assigned to either an intervention group receiving twice-weekly individual music therapy sessions over twelve weeks, or a control group continuing with usual care.

Sessions were delivered by registered music therapists who tailored each playlist to the participant's life history, cultural background, and personal preferences. Common choices included wartime-era big band tracks for older veterans, classical pieces for those with European heritage, and country or rock classics for residents who grew up in regional Queensland. Researchers measured agitation using validated tools completed by blinded care staff at three points: baseline, mid-trial, and follow-up one month after sessions ended.

What the Findings Show

Residents in the music therapy group showed a statistically significant reduction in overall agitation scores compared with controls. The greatest improvements appeared in verbally agitated behaviours such as calling out and repetitive questioning, while physically aggressive behaviours also declined, though more modestly. The benefits persisted for at least four weeks after the formal sessions stopped, suggesting music engagement had lasting calming effects rather than transient distraction.

Secondary outcomes were equally encouraging. Staff observed increased social interaction during and after sessions, with several residents joining group singing in communal areas. Family members reported fewer distressing phone calls and visits. The intervention also appeared to reduce the need for as-required sedative medications, a finding that aligns with broader Australian efforts to minimise chemical restraint in aged care settings.

Aged Care Reforms and Music Therapy

The findings land at a pivotal moment for the sector. The recommendations of the Royal Commission into Aged Care Quality and Safety continue to reshape expectations around dignity, choice, and clinical care for older Australians. New aged care reforms are pushing providers to demonstrate evidence-based, non-pharmacological strategies for managing behavioural and psychological symptoms of dementia. Music therapy, with its strong evidence base and minimal side-effect profile, is well placed to meet these expectations.

Funding remains a practical hurdle. Music therapy is not currently listed as a subsidised allied health service under the mainstream aged care funding instrument in the way physiotherapy or dietetics is. Some Queensland providers absorb the cost through discretionary lifestyle budgets, while a growing number of community organisations partner with universities to offer student-led programs. Resources such as this guide from Brisbane Diamantina Health Partners outline how translation research is helping bridge the gap between clinical trials and everyday care delivery in residential settings. Parallel research into group-based models of care points the way toward more efficient delivery of allied health services in community settings, an approach that could complement individual music therapy as demand grows.

Translating the Evidence into Daily Care

For aged care managers considering implementation, the study offers a workable template. Successful programs tend to start small, train lifestyle staff in basic techniques, and refer complex cases to qualified music therapists for assessment. Family involvement also helps, with relatives encouraged to share meaningful songs that can be loaded onto a dedicated device at the bedside. Cultural safety matters too, and providers serving diverse communities in cities like Melbourne or Sydney may need multilingual playlists and culturally adapted session formats to achieve similar results.

Looking beyond residential care, researchers are exploring how music therapy could complement other community-based interventions. The growing interest in social prescribing approaches suggests a future in which doctors might refer patients to choirs, drumming circles, and other musical activities in addition to allied health services. Together, these directions point toward a more holistic, person-centred future for dementia care across Australia.

The next step belongs to those who fund, deliver, and advocate for dementia care. Aged care executives in Brisbane and regional Queensland can pilot music therapy programs in partnership with local universities. Clinicians can refer eligible residents to registered music therapists through My Aged Care assessments. Families can request that culturally meaningful music be built into their relative's care plan. And researchers can continue building the translational evidence base that turns promising studies like this one into standard practice across Australian aged care.
