Abstract

Deficits in facial emotion recognition in Huntington's disease (HD) have been extensively researched, however, a theory-based integration of these deficits into the broader picture of emotion processing is lacking. To describe the full extent of emotion processing deficits we reviewed the clinical research literature in HD, including a consideration of research in Parkinson's disease, guided by a theoretical model on emotion processing, the Component Process Model. Further, to contribute to understanding the mechanisms underlying deficient emotion recognition, we discussed the literature in light of specific emotion recognition theories. Current evidence from HD studies indicates deficits in the production of emotional facial expressions and alterations in subjective emotional experiences, in addition to emotion recognition deficits. Conceptual understanding of emotions remains relatively intact. Impaired recognition and expression of emotion in HD might be linked, whereas altered emotional experiences appear to be unrelated to emotion recognition. A key implication of this review is the need to take all the components of emotion processing into account to understand specific deficits in neurodegenerative diseases.
