Central Auditory Processing Modulation Underlying Anxiety Reduction Using Clinically Designed Improvisatory Music
This study examines whether Clinically Designed Improvisatory Music (CDIM) can reduce anxiety in people living with Alzheimer's disease and anxiety (AD-A), and whether it can also lessen caregiver burden. CDIM is a live, receptive music-based intervention that uses slow tempi, simple diatonic melodic lines, soft dynamics, and periodic pauses to promote relaxation. As described in the proposal, CDIM has previously been shown to reduce stress and improve physiological markers such as heart rate, blood pressure, and EEG alpha/beta ratios (CDIM significantly decreased physical stress symptoms and patients also reported positive emotional outcomes and EEG readings showed increased alpha/beta brainwave ratios ).
The study will enroll 30 dyads (individuals with AD-A and their caregivers). Dyads will be randomly assigned to either CDIM or a control intervention (CI) consisting of calming short stories read aloud. Both interventions include eight 30-minute sessions over four weeks, delivered in alternating in-person and virtual formats.
The primary goal is to determine whether CDIM is feasible and effective in reducing anxiety in individuals with AD-A, measured by the Rating Anxiety in Dementia (RAID) scale, and in reducing caregiver burden, measured by the Zarit Burden Interview (ZBI). The study also evaluates changes in heart rate and blood pressure as indicators of autonomic regulation.
A second goal is to explore whether CDIM improves central auditory processing, assessed using the frequency-following response (FFR). The proposal notes that central auditory processing declines with age and dementia and may contribute to anxiety. FFR will be measured before and after the intervention to determine whether CDIM enhances neural timing and response magnitude.
Overall, this pilot study aims to determine whether CDIM is a feasible, safe, and potentially effective non-pharmacological intervention for reducing anxiety in individuals with AD-A and decreasing caregiver burden, while also investigating its underlying neurophysiological mechanisms.

実験的：Clinically Designed Improvisatory Music
|
Clinically Designed Improvisatory Music (CDIM) is live, slow-tempo, diatonic improvisation played with soft dynamics and periodic pauses.
It uses meterless melodic lines, vocal-range pitches, and gentle harmonic intervals to promote neural entrainment, parasympathetic activation, and anxiety reduction in listeners.
