A new review suggests that music therapy may offer meaningful benefits for people living with neurological, psychiatric, and chronic health conditions, but its wider adoption in clinical practice continues to be limited by workforce shortages, inconsistent standards, and gaps in research.
Published in Frontiers in Human Neuroscience, the review describes music therapy as a safe, person-centered intervention that bridges neuroscience, medicine, and the humanities, with the strongest evidence seen in dementia care. Researchers report that music-based interventions can help manage symptoms across a wide range of conditions, including Parkinson's disease, stroke, traumatic brain injury, schizophrenia, autism spectrum disorder, depression, insomnia, and in palliative care.
The authors note that music therapy is gaining attention as health systems search for non-drug approaches to support aging populations and reduce the risks of polypharmacy. They highlight that musical memory circuits often remain preserved even in advanced Alzheimer's disease, allowing music to evoke emotions, autobiographical recall, and communication when other cognitive abilities have declined.
In dementia care, studies show that music therapy can improve attention, speech, and autobiographical memory, while also reducing agitation, anxiety, and behavioral disturbances such as aggression and wandering. Group singing and structured music programs have been associated with fewer behavioral symptoms, reduced fall incidence, and lower use of antipsychotic medications in long-term care settings.
Beyond dementia, the review highlights evidence supporting music therapy in stroke rehabilitation, where rhythmic and melodic cues may stimulate neural plasticity and support recovery of motor and language functions. In Parkinson's disease, Rhythmic Auditory Stimulation has been shown to improve gait, balance, and stride length, and reduce freezing episodes. For people with schizophrenia, adjunct music therapy has been linked to improvements in mood, social functioning, and negative symptoms.
The review also notes benefits for depression, insomnia, autism spectrum disorder, and in palliative care, where music can help reduce pain, distress, and caregiver burden.
Despite its therapeutic potential, the authors caution that music therapy is not universally soothing and may evoke distressing or traumatic memories in some individuals. They emphasize the importance of informed consent, cultural sensitivity, and careful monitoring, particularly for patients with cognitive impairment who may not be able to verbally express discomfort.
Implementation challenges remain significant. The field faces methodological variability, limited reimbursement, inconsistent therapist training, and a shortage of qualified practitioners, especially in dementia and palliative care settings. The authors call for standardized reporting frameworks, stronger referral pathways, and expanded access through in-person, virtual, and hybrid models of care.
The authors recommend implementing policies, to integrate music therapy into disease-specific care pathways, establish reimbursement mechanisms, and prioritize patient-and caregiver-centered outcomes in future research.
The review concludes that while music therapy holds promise as a non-pharmacological tool to support emotional, cognitive, and social well-being, more rigorous long-term studies and stronger health system integration are needed to ensure equitable and sustainable access to these interventions.
