Music Cognition in Frontotemporal Dementia and Non-Alzheimer’s Dementias

This chapter examines how music knowledge is affected in non-Alzheimer’s dementias, with a focus on frontotemporal dementia syndromes. It discusses the clinical and neurobiological rationale for studying music knowledge in non-Alzheimer’s dementia. It describes some of the ways in which music knowledge has been investigated in these patients, what musical abilities are lost or preserved in non-Alzheimer’s dementia, and how this information helps us improve our knowledge of how the brain processes music. The social role of music in evolution is briefly discussed. The chapter examines how emotions generated by and recognized in music are processed differently in frontotemporal dementia compared to healthy individuals and Alzheimer’s disease patients, including the phenomenon of musicophilia, the abnormally enhanced craving for music. Finally it explains how the differences in emotion processing between dementia diseases highlight the need for some selectivity in designing music-based therapies.
