Research Evidence

Comprehensive scientific evidence supporting music therapy for dementia, ADHD, Down Syndrome, and personality-aligned playlist design.

Dementia & Cognitive Health

Music therapy improves orientation, episodic recall, agitation, and quality of life metrics across mild-to-moderate dementia cohorts. Meta-analyses highlight strongest gains when culturally familiar repertoires are used.

  • Systematic reviews (Moreno-Morales et al., 2020) report clinically meaningful improvements on cognitive scales and anxiety inventories.
  • Longitudinal trials demonstrate reduced caregiver burden when playlists are aligned with autobiographical memory triggers.
  • EEG and imaging studies show enhanced frontal alpha synchronisation and memory-network activation following structured music listening blocks.

ADHD & Executive Function

Structured rhythm, amplitude modulation, and binaural beat scaffolding strengthen sustained attention, working memory, and inhibitory control for paediatric and adult ADHD cohorts.

  • Beta-band (16 Hz) modulation in background music improves sustained attention, with greatest benefit for high ADHD-trait listeners.
  • Gamma (40 Hz) binaural beats synchronise EEG microstates and enhance working-memory performance.
  • Clinical RCTs show 15 Hz binaural beats improve subjective study performance for adults with ADHD.

Down Syndrome & Sensory Integration

Active music engagement and 40 Hz sensory stimulation promote neurogenesis, memory formation, and socio-emotional development for individuals with Down Syndrome.

  • MIT Picower Institute studies show 40 Hz light + sound stimulation improves cognition and hippocampal connectivity in Down Syndrome models.
  • Orff-based music and movement programmes increase attention span and memory retention in children with Down Syndrome.
  • 528 Hz music interventions reduce cortisol, elevate oxytocin, and improve mood scores, indicating powerful autonomic regulation.

Big Five Personality & Musical Preference

Large-scale personality studies confirm durable correlations between trait profiles and musical preferences, validating personality-aligned playlist generation.

  • Openness strongly predicts preference for diverse, sophisticated, and experimental genres.
  • Extraversion correlates with contemporary, upbeat, and rhythmically engaging music across global populations.
  • Neuroticism aligns with intense musical styles, highlighting the need to balance catharsis and relaxation strategies.

Caregiver & Home Delivery Models

Family-delivered interventions, home-based playlists, and choir participation provide scalable music therapy pathways outside clinical settings.

  • HOMESIDE and similar trials demonstrate clinically meaningful reductions in behavioural symptoms when caregivers deliver personalised playlists.
  • Recreational choir singing sustains depression improvements for 12 months and augments quality-of-life measures.
  • Hybrid models combining active and passive music work best when tailored to stage of cognitive impairment.

Integrated Therapeutic Framework

TheraMuse RX combines personality insights, nostalgia windows, and reinforcement learning to deliver evidence-aligned therapy playlists.

  • Patient context drives personalised YouTube retrieval with strict filters against non-music content.
  • Feedback loops update Linear Thompson Sampling bandits, automatically improving recommendation quality.
