Abstract

Music-based interventions are a common feature in long-term care with clinical reports highlighting music’s ability to engage individuals with complex diagnoses. While these findings are promising, normative findings from healthy controls are needed to disambiguate treatment effects unique to pathology and those seen in healthy aging. The present study examines brain network dynamics during music listening in a sample of healthy older adults before and after a music-based intervention. We found intervention effects from hidden Markov model-estimated fMRI network data. Following the intervention, participants demonstrated greater occupancy (the amount of time a network was occupied) in a temporal-mesolimbic network. We conclude that network dynamics in healthy older adults are sensitive to music-based interventions. We discuss these findings’ implications for future studies with individuals with neurodegeneration.
音乐干预后老年人听音乐时的网络连接差异
以音乐为基础的干预措施是长期护理中的一个常见特点,临床报告强调音乐能够吸引患有复杂诊断的患者。虽然这些研究结果很有希望,但还需要健康对照组的标准研究结果,以区分病理学和健康老龄化所特有的治疗效果。本研究以健康老年人为样本,研究了在音乐干预前后听音乐时大脑网络的动态变化。我们从隐藏马尔可夫模型估计的 fMRI 网络数据中发现了干预效果。干预后,参与者在颞叶-边缘网络中表现出更高的占用率(网络被占用的时间量)。我们的结论是,健康老年人的网络动态对基于音乐的干预很敏感。我们将讨论这些发现对未来神经变性患者研究的影响。
