The objective of this cross-sectional study was to determine the extent and nature of self-reported musical abilities in persons with mild cognitive impairment (MCI). We recruited 60 older adults with a diagnosis of MCI from the Alzheimer's disease Core Center. We evaluated self-reported musical abilities using the Goldsmiths General Musical Sophistication Index. We examined correlations between musical abilities and neuropsychological measures of verbal learning and memory, processing speed, executive function, verbal fluency, naming and visuoconstructive abilities, while controlling for key demographic and participant characteristics. Older adults with MCI reported varying degrees of musical abilities. Nearly half of participants reported that they did not engage in regular, daily practice of a musical instrument. When adjusting for key demographic and participant characteristics, we found modest associations between four musical ability subfactors (active engagement, perceptual abilities, musical training and emotional engagement with music) with three cognitive abilities: verbal fluency, executive function and verbal naming. Except for the emotional engagement with music subfactor, none of the remaining musical ability subfactors correlated with any demographic or participant characteristics. While our study findings provided further support for the relationship between musical and cognitive abilities in older adults with MCI, this relationship warrants further investigation.
这项横断面研究的目的是确定轻度认知障碍（MCI）患者自我报告的音乐能力的程度和性质。我们从阿尔茨海默病核心中心招募了60名被诊断为MCI的老年人。我们使用戈德史密斯一般音乐素养指数评估自我报告的音乐能力。在控制关键人口统计学和参与者特征的同时，我们研究了音乐能力与言语学习和记忆、处理速度、执行功能、言语流畅性、命名和视觉构建能力的神经心理学测量之间的相关性。患有MCI的老年人报告了不同程度的音乐能力。近一半的参与者报告说他们没有定期进行日常乐器练习。在调整关键人口统计学和参与者特征后，我们发现四个音乐能力子因素（积极参与、感知能力、音乐训练和对音乐的情感参与）与三种认知能力之间存在适度关联：言语流畅性、执行功能和言语命名。除了对音乐的情感参与子因素外，其余音乐能力子因素均与任何人口统计学或参与者特征无关。虽然我们的研究结果为患有MCI的老年人的音乐能力和认知能力之间的关系提供了进一步支持，但这种关系仍需进一步研究。
