Neurophysiological Benefits of Live Music for Early Alzheimer's Patients and Their Caregivers

Analysis of recordings captured during live concerts will be conducted using music information retrieval, pulse clarity, psychological ethnography, and similar methods. Investigators hypothesize that live music will reduce anxiety, increase social motivation, elevate parasympathetic activity, and enhance neural synchrony yielding increased interpersonal coordination, harmony, and emotional connection within dyads, indicating a positive impact on their autonomic nervous system and emotional well-being. The primary objective of this study is to investigate the neurophysiological effects of live music concert experiences on people living with early AD and their caregivers using EEG and HR monitoring. The secondary objectives of this study are to: * Understand whether the live concert experience reduces state anxiety and enhances connection between individuals with early AD and their caregivers. * Determine what role the physical characteristics of the concert music have on the wellbeing, behavior, connectedness, and autonomic function of people with early AD and their caregivers. In-person sessions of the study will be conducted at a music / event venue in either the Greater New Haven, CT area, with possible expansion to venue(s) in the Washington, DC area, and/or the Nashville, TN area. The Yale IRB-approved study team may conduct the study at additional locations (including in the Washington, DC area and the Nashville, TN area) with permission from the venue(s). Each participant will take part in two sessions. Both sessions will last up to 3 hours. Participants will attend a series of live music performances and pre-recorded control session performances. Physiological and survey data will be collected to assess the impact of live versus pre-recorded music on anxiety, social motivation, parasympathetic activity, and neural synchrony.
