Abstract

A 62-year-old musician-MM-developed amusia after a right middle-cerebral-artery infarction. Initially, MM showed melodic deficits while discriminating pitch-related differences in melodies, musical memory problems, and impaired sensitivity to tonal structures, but normal pitch discrimination and spectral resolution thresholds, and normal cognitive and language abilities. His rhythmic processing was intact when pitch variations were removed. After 3 months, MM showed a large improvement in his sensitivity to tonality, but persistent melodic deficits and a decline in perceiving the metric structure of rhythmic sequences. We also found visual cues aided melodic processing, which is novel and beneficial for future rehabilitation practice.

右侧大脑中动脉梗塞后获得性失神--病例研究。

一名 62 岁的音乐家（MM）在右侧中脑动脉梗塞后出现了失音。最初，MM 在辨别旋律中与音高有关的差异时表现出旋律障碍、音乐记忆问题以及对音调结构的敏感性受损，但音高辨别力和频谱分辨率阈值正常，认知和语言能力正常。除去音高变化后，他的节奏处理能力完好无损。3 个月后，MM 对音调的敏感度有了很大提高，但旋律障碍依然存在，对节奏序列的度量结构的感知能力也有所下降。我们还发现视觉线索对旋律处理有帮助，这对未来的康复实践是新颖有益的。

期刊介绍： Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
