Perception of Emotion on Faces in Frontotemporal Dementia and Alzheimer’s Disease: A Longitudinal Study

Abstract

Recognition of emotion on faces in AD decreases with the progression of dementia and could be related to the progression of the degeneration of the structures implicated in emotional processing systems. Inconsistency of the results in FTD may be related to impulsiveness, lack of consistency of the patients and to heterogeneity of the progression of the lesions.
