Preserved musical semantic memory in semantic dementia.


ABSTRACT:

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.
