ASSESSING DYNAMIC AFFECT RECOGNITION FOR DISTINGUISHING FRONTOTEMPORAL DEMENTIA SUBTYPES

Our findings indicate that emotion reading tests using dynamic stimuli are best for differentiating among FTD syndromes. Also, unique profiles of emotion reading deficits emerging from different syndromes correspond to distinct patterns of damage to emotion, semantics, attention, and reward-related brain networks. Emotion identification deficits are a core feature of FTD, therefore careful selection of tests that reflect the key underlying neural circuits will result in more accurate phenotyping.
