摘要
Objective: To understand the scope of semantic impairment in semantic dementia. Design: Case study. Setting: Academic medical center. Patient: A man with semantic dementia, as demonstrated by clinical, neuropsychological, and imaging studies. Main Outcome Measures: Music performance and magnetic resonance imaging results. Results: Despite profoundly impaired semantic memory for words and objects due to left temporal lobe atrophy, this semiprofessional musician was creative and expressive in demonstrating preserved musical knowledge. Conclusion: Long-term representations of words and objects in semantic memory may be dissociated from meaningful knowledge in other domains, such as music. Arch Neurol. 2011; 68(2):248-250
