Abstract
Introduction Patients with neurocognitive disorders (NCD) commonly experience a range of psychiatric symptoms such as depression, anxiety, psychosis, and agitation. 1 These comorbidities complicate the course of treatment for these patients as well as exacerbate caregiver burden. Since pharmacologic interventions are known to pose significant risks to these patients, there is great urgency to find additional non-pharmacologic options to improve quality of care. 1 Music therapy is becoming a more frequently used tool in different treatment settings and has been shown to improve anxiety and depression, however intensive and structured music therapy can also be a cost burden for residential facilities. 2 , 3 This study's aim was to assess the short-term benefits of a live music performance for residential patients with mild and moderate major NCD. Methods This is a prospective, non-blinded, longitudinal comparison study. Inclusion criteria were age 65-100, English speaking, and had either a diagnosis of major NCD, cognitive disorder, or dementia of the mild to moderate stage that required institutionalization at a residential facility. Exclusion criteria were severe presbycusis, and diagnosis of dementia or NCD of the severe stage. Participating residential facilities with connections to the Symphony of Soul Foundation and St. David's Foundation were asked to publicize this study to residents and their legally authorized representatives (LAR). The participants would then provide informed assent and consent, respectively, to enroll. The study intervention was a 30 minute live-performance of a set list of popular music from the 1930s-1950s (English language), given by a standard performer. The main statistical analysis will be a multivariate repeated measures comparison of scores that assess cognition, depression, and quality of life using the Montreal Cognitive Assessment (MoCA), Geriatric Depression Scale (GDS), and the Cornell-Brown Scale for Quality of Life (CBSQoL). The scales were administered 1 week before the study intervention to participating subjects for baseline scores, and then re-administered 1 week after the intervention. Different versions of the MoCA (v.1 and v.2) were used for the pre- and post-intervention assessments. Results A total of 8 subjects (n=8) and their respective LARs provided assent and consent to participate in the study. There was 1 complete dropout before the study began. The mean MoCA score pre-intervention, MoCApre = 7.3, with a 95% CI = [2.36, 12.25]; the mean MoCA score post-intervention, MoCApost = 9.4, with a 95% CI = [3.41, 15.39]; the difference between the two mean MoCA scores was not statistically significant, since the 95% CI for this difference was [-5.65, 9.85]. Subjects did not have scores that indicated clinical depression throughout the study, with a mean GDSpre = 1.5, and a mean GDSpost = 2.2. The mean CBSQoLpre = -3.67, with a 95% CI = [-10.91, 3.57]; the mean CBSQoLpost = 17, with a 95% CI = [10.86, 23.14]; the CBSQoL scores between the two groups had statistically significant difference as evident in non-overlapping CIs; the 95% CI for the difference between the two mean CBSQoL scores was [11.19, 30.15]. Conclusions This study's initial results suggested that there was a statistically significant improvement in the subjects’ quality of life after a brief, live-musical performance. However there were no significant differences in the subjects’ cognition and mood. The labor intensity that was required for the subjects to complete the pre- and post- intervention assessments was a notable barrier for them to participate effectively as evident by the dropout rate, and was also a deterrent for additional eligible subjects to enroll in the study. Decreasing the difficulty for subjects to participate in the future (e.g., through optimizing the testing environment, shortening the music performance) might therefore increase the sample size and improve the study's power and validity This research was funded by: Symphony of Soul Foundation, St. David's Foundation
